Not Dead Yet

Just a brief update. Still unpacking and getting settled in to the new digs. Don't even have a place to set up my chessboard yet. I'll also be out of town next weekend.

If I get my books unpacked I'll try to post something substantive before the trip.

An Aside on Opening Preparation

Just thought I would clarify my stance on opening preparation, prior to the next installment of my series.


I think it's important to analyze your games--even online blitz. Part of that analysis should include how the opening was treated. Of course, you'll also be looking for errors in tactics, endgames, and strategy as well, but I don't think the opening should just be ignored, regardless of your chess strength.


If you do not want to maintain an openings repertoire, and just fly by the seat of your pants, then you could keep your opening study down to spotting gross errors. However, if you've ever bought an opening book with the intent of playing certain lines routinely, I strongly feel you need to understand the suggested moves, and have followed the main line through the opening so that you understand what each side is aiming for. If you're plopping money down on opening books, but just "looking up the answer" to what you should have played, or just trying to memorize lines, you're wasting time and money. You owe it to yourself to try and understand the lines you want to play, and I believe that studying openings in this limited but focused way can improve your chess as a whole.


For example, perhaps you learn that Black plays ...d5 at some point to prevent e4. If you understand that, and your opponent omits the "book move" of ...d5, that serves as an alert: Perhaps it would be good for you to push e4 in response. Or perhaps Black normally avoids exchanging a bishop for a knight, and your opponent doesn't. That suggests that winning the bishop pair may be a good idea.


The main lines of your opening are models of good opening play. Understanding them helps you to find good opening moves for yourself, and directs you towards reasonable middlegame strategies.


When you're not analyzing your own games, go ahead. Study tactics. Study endgames. Play through master games. Practice martial arts so you can strike the button on the clock with the reflexes of a cobra. Whatever you think helps your game more, or whatever tickles your fancy. Knock yourself out.


However, when it comes to analyzing your own games, I think you need to consider the game in its entirety, including the opening. Don't just focus on the knight you dropped in the midgame, but also the tactic you missed that would have regained it; the endgame you could have drawn a piece down; and the opening error that led to the difficult position you blundered in.

Learning New Routes

Still busy unpacking into the new home. My computer is being cantankerous (stupid nvidia graphics driver causing crashes) but thought I'd pass on a quick analogy.

I'm currently learning how to get around in a new city. Right now it seems like the civil engineers are purposely trying to thwart people...no U turn here, no left turn allowed there, have to drive 3/4 of a mile just to turn around and get into the strip mall across the street. I knew my old routes so well I could drive on autopilot, even with all the finesses gained by experience (e.g. get in the left lane here, because the right lane will slow a half mile ahead). I've gone from rarely checking a map to needing a mapquest printout to get to the grocery store. I'm learning where the major destinations are and where the major highways lead and intersect, and not worrying as much about street names until I need to find a certain address.

Learning the ins and outs of a new opening is similar. Worry about the main roads first that lead to the most important destinations. As you do this, think about how you're getting there (why do I have to get in the right lane here? Why do I play ...h3 here?) until it's second nature. Learn new roads as required by need...don't try to memorize the entire map at once. Years later there'll still be places you're unfamiliar with, but you can find your way from one end of town to the other by feel if necessary.

Next Post Delayed

I am in the process of moving. The last post in the opening preparation series will be delayed until we're moved, unpacked and reconnected to the internet, which will take a week or more.

In contrast to the first two posts in the series, this one is requiring me to put in a lot of independent study because it's an example of what to do when opening repertoire books alone can't guide you. So I'll need a little time to unpack my library, get settled in, and finish the analysis.

Hopefully your patience will be rewarded.

How to Prepare an Opening, Part Two

Here we're going to hack our way through the jungle and eventually arrive at the main line of the Closed Spanish. I've tried to come up with phrases that describes what we're about to do:

  • spelunking
  • going on an Opening Safari
  • dumpster diving
  • mining for gold
  • antiquing (when using old games and analysis to guide your thoughts)

The bottom line is we're going to be trying to understand the reason behind the main move order, question it, and see if we can find other sequences we like better.

Even if you're using a repertoire book for guidance, follow this thought process so that, at the very least, you've justified their move choice. If you think about the move for a bit, you're helping to transfer this move from short-term to long-term memory. I strongly recommend using an actual chess board, because I think it assists with this transfer.

We'll first go over the main line and see what each side is thinking. If these reasons for the moves aren't clear already, you can refer back to this sequence as we discuss alternatives. The ideas are superficial but they'll do. This is my own interpretation of the opening sequence. I may revise this if Marin's upcoming book on the Spanish turns more light bulbs on. Before I undertook this exercise, it wasn't clear to me why certain key moves for both sides (0-0, c3, and h3 for white; ...Be7, ...b5, ...0-0 and a possible ...Bg4 by Black) were played in a certain sequence. By going through this exercise, the picture is now a lot clearer. I recommend this technique of using an "internal Socratic dialogue (monologue?)" for any opening you work on....ask questions and try to answer them.

After 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6:

5.0-0 ("I know my e4 pawn is attacked, but I've figured out how to deal with it")
5...Be7 ("I could take the e4 pawn, but I've figured out it can't really be kept, so I choose to develop.")
6.Re1 ("Ok, now I should protect e4. This also will clear f1 for a N manoeuvre I have planned.")
6...b5 ("I want to kick-start my queenside play before White can make an escape square at b2 for his bishop")
7.Bb3 d6 ("I want to play ...Na5 to chop the B off, but e5 is weak. This shores up my center and opens a diagonal for the queen's bishop.")
8.c3 ("I want to keep my bishop in case of ...Na5")
8...0-0 ("castling is good")
9.h3 ("I want to play d4, but if he pins me with Bg4 that's annoying.")
9...Bb7 ("develops the bishop on the long diagonal and hits e4"). Black has several options at this point. I've chosen this move because it completes Black's development (except for queen deployment), which is a good enough stopping point for this tutorial. If I were white, I would look at the main lines enough to get an idea for how my development will be completed (e.g. the standard Spanish N manoeuvre of Nb1-d2-f1-g3 or e3); as Black, I would choose my system starting at move 9 and extend the main line from there a short distance, in order to get a feel for the types of middlegames that ensue.

At lower levels of play, it's not that likely that your opponent makes it all the way through even the "mainest" of main lines without diverging at some point. In that case, studying the opening out further than the end of development won't pay direct dividends in your own games (although indirectly this may increase your understanding of typical play). You're better off, in my opinion, studying master games than worrying about exact move sequences here. When your opposition starts playing these lines through, then you can worry about extending your horizon.

I'm now going to cross-examine the main Spanish move sequence, see if I agree with it, and see if I can find alternatives for either side.

The first, obvious, question about 5.0-0 is: why doesn't White have to protect the e4 pawn? If you're castling here because it's the book move, but don't have an answer for this question, you're asking for trouble. 5...Nxe4 (the Open Spanish) is a reputable opening choice:


The standard move here is 6.d4. 6.Re1 is playable but should cost White the bishop pair. Now, the books say "it's too risky to play 6...exd4 in this position". This should trigger your intellectual curiosity. It turns out that this is called the Riga variation, and the main reason for that assessment is the endgame after 7.Re1 d5 8.Nxd4 Bd6! 9.Nxc6 Bxh2+!

















Here, 10.Kh2 allows perpetual check by 10...Qh4+ 22.Kg1 Qxf2+. So, if a draw is an acceptable result for you, this is fine. The main continuation for White is 10.Kh1! Qh4 11.Rxe4+! dxe4 12.Qd8+! Qxd8 13.Nxd8+ Kxd8 14.Kxh2+/= (see next position):


















Emms, for example, says that this endgame "has been known for many years to favour White" and leaves it at that. In my database, White scores 68%, which certainly backs this up. However:

1. This is a fairly forcing variation (although some homework on your part will be required). White has to find some good moves. If you're ok with a draw, this can be a good practical chance at club level.

2. If this were just a trappy, tactical line I probably wouldn't be attracted to it. However, ask yourself if the endgame (more like a queenless middlegame, in my opinion) is that bad for black.











Here's what I see:
  • material is unbalanced but roughly equal. Two minor pieces + bishop pair = 3.25x2 + 0.5 = 7 pawns, balancing a rook plus two pawns. I'm using the Kaufman values for the pieces...see this Heisman article for an elaboration.
  • black nominally has a lead in development, but at a glance I don't think Black will be able to keep it because he has to untangle a bit.
  • Black has action for his rooks on the center files, and a 4:2 pawn majority on the king side. White's N has no outpost, but the open position is good for the two bishops.

This is some shallow analysis, and perhaps the best thing is to play the position from both sides against the computer to see how you really feel about Black's position. My suspicion is that Grandmaster technique makes this easier for white, but at club level familiarity with the position will triumph. I think that this would be an interesting line to try out in actual play.

Even if you don't go for the Riga Variation, the Open Spanish with 5...Nxe4 is a real option for Black's repertoire.

So, it turns out that White can get away with 5.0-0. It also turns out that White can play 5.d4 here. Remember a rule of thumb for White in these openings is "if you can get away with d2-d4, it's probably a good move." It turns out that 5.d4 (or 6.d4 after 5.0-0 Be7) is fully playable. Johnsen and Johannessen call this the "Central Attack Ruy Lopez (CARL)". The authors say that it's drawish but that Black has to walk a narrow path. If this is the GM assessment, that means that this would be perfectly acceptable for club players. Your opponents aren't likely to have figured out an antidote to this variation; I have never faced it myself. J&J give a fair bit of analysis in this line; Davies' repertoire book for Black only considers the 6.d4 move order. I played through much of J&J's analysis, and my gut feeling was that White was making a lot of pawn moves and falling behind in development, but had nicer pawns at the end.

{NEW: 9/22/07} When I initially prepared this I glossed over 5.d3. In Marin's A Spanish Repertoire for White, he devotes an entire chapter to this move (which can be played "anywhere between the 5th and 10th moves). I'll just point out that it logically protects the e4 pawn, and that it's respectable. It's a bit timid for my taste, but it would be a good compromise for those wanting to play a "grownup" opening yet also deviate early to throw off your opponent.

Black has a few other 5th-move options after 5.0-0. Both 5...Bc5 and 5...b5 with 6...Bc5 (the Moller variation) opt to place the king's bishop on its other viable posting (Bd6 blocks the d-pawn, Bb4 allows c2-c3 with tempo). 5...b5 with 6.Bb7, the Arkhangelsk, develops the queen's bishop to the long diagonal. I will leave it up to someone with more experience from the White side as to how common it is to see these in club play; I'll just say that the moves make sense and are respectable.

For the most part I'm glossing over variations where White captures on c6. I'll just point out that some black players are annoyed enough by the Delayed Exchange Ruy Lopez Deferred (what a name!) with 6.Bxc6 that they play 5...b5 as above and only then 6....Be7.

Referring back to the main line now: after 5.0-0 Be7 6.Re1 the moves 6...b5 7.Bb3 are almost always seen. If Black delays, White plays c2-c3, and his bishop will reach c2 in one move instead of two.

Now, 7...0-0 is possible instead of 7...d6. The main difference here is that, if you castle on move 7 instead of move 8, your opponent may think you're going to play the Marshall Gambit (8.c3 d5!?). If you're perfectly happy with your opponent freaking out and avoiding a main-line Spanish by playing an "anti-Marshall" move like 8.a4, 8.h3, 8.d4 or 8.d3, go for it. If you were hoping to reach a main-line Spanish, then you're more likely to get it by playing 7...d6 here.

At this point, White normally plays 8.c3 here so that 8...Na5 doesn't lose the bishop. This move also helps prepare d2-d4, so it seems like the most natural choice. If you ask yourself, "Can I play d4 here?" the answer is "not really". The main point is that after 8...Nxd4 9.Nxd4 exd4, White can't play 10.Qxe4? because of the "Noah's Ark Trap": 10...c5 11.Qe3 c4 -+. I won't go into moves such as 8.a4 and 8.d3 except to say they're playable and may transpose to other lines.

White will probably play 9.h3 to avoid the ...Bg4 pin next move, so 8...Bg4 seems like a sensible alternative for Black here. I have not fully determined why it's not normally played. The "antidote" seems to be d2-d3, h2-h3, and Nb1-d2-f1-g3 for White, but that's not clearly bad for Black, and 8...Bg4 was actually played by Karpov against Short. This may be another opportunity for Black to do some homework and play an offbeat line.

If white omits h2-h3 and plays 9.d4 instead, 9...Bg4 is now supposed to be uncomfortable for White to play against. However, this is still a respectable option for White. Black is threatening to win the d4 pawn, so White has to be prepared to deal with this (e.g. 10.Be3 or 10.d5). 9.d3 here, or at many points in the Spanish, is playable but feels timid to me.

So, we can see that, compared to many openings, the Spanish has a very clear and logical main line. However, as I also showed here, even this classic opening sequence has lots of opportunity for both sides to deviate before Black's move 9. There's plenty of opportunity for a player to diverge and fight your opponent on your own turf. However, I would only diverge from the main line because you genuinely prefer your moves, rather than just diverging for the sake of "getting your opponent out of book".

To summarize the last two posts:

1. Become familiar with basic opening rules of thumb. Then, choose the opening moves that you want to play based on basic principles and guided by theory. When you don't have an overwhelming preference for one move, steer towards "respectable" openings that offer a variety of pawn structures and piece deployments.

2. Map out a "main line" where you decide what you would play against your opponent's "best" response. Chessbase's opening statistics makes it easy to determine what these "best" lines are, but use whatever resources you have (Nunn's Chess Openings, Modern Chess Openings, Fritz's opening book). If you're not sure which is "best", just choose one. Map this main line out until the approximate end of the opening phase (ideally, where all your pieces are developed and you've castled). This is generally about 9-12 moves.

I think the more clearly you understand the main line of your openings, the better equipped you are at dealing with your opponents' deviations. For example, White omitting c2-c3 when its called for may be a sign to seize the bishop pair with ...Na5.

The hardest, most time-consuming part is determining what your main lines will be. After that, your focus will be on analyzing your own games and determining how you'll deal with other lines as you encounter them. I think this is one area where internet blitz can be helpful...you can get a large number of examples of how players of your level treat the opening. You may find that "inferior" lines such as the Steinitz or Cozio variations of the Spanish are actually the "main lines" at your level.

So, what if your opponent plays something odd? The next post will will show an example of opening preparation triggered by my opponent's novelty. It will also show the limitations of opening repertoire books compared to general familiarity with the opening.

How to Prepare an Opening, Part One

I am going to demonstrate a thought process that would result in choosing the main line (closed) Spanish (a.k.a. Ruy Lopez) for both white and black. The Spanish is a good choice for this demonstration, because the main line for both sides up to move 9 or so is fairly clear. It also happens to coincide (mostly) with what I play myself, so I can pretend to speak with some authority. Finally, I suspect most amateurs have at least some familiarity with the opening. This is good, because I want people to focus on the thought process behind constructing the repertoire, rather than the opening itself.

Part One is just an introduction to the process. I imagine many people reading this won't find the first 5 moves of the Spanish too mysterious. The next post in the series will be more advanced, and show how you can, with a little research, come up with your own pet lines to surprise your opponents. After that, I hope to show a real-world example of opening preparation, where an opponent's odd treatment of the Nimzo-Indian demonstrates how opening books can lead you into a dead end. Even people that have played the Nimzo for years may learn something there. So, if this post strikes you as "baby talk", bear with me. I'm hoping by the end of the series that most readers have learned a thing or two.

Let's consider the first move for White. From general opening principles, you want to control the center and open lines for your pieces to come out. To me, the most natural moves are 1.d4 and 1.e4. Other moves such as 1.c4 and 1.Nf3 are perfectly acceptable, but they don't have the clear idea behind them that 1.d4 and 1.e4 do. From my own experience, and from the opinions of many chess trainers, I would say 1.e4 is the best choice for developing players. Just consider this advice (and other opinions that follow) as a "tie-breaker". If you did choose 1.d4, the only warning I'd have is not to play some system like the Colle or Stonewall that lead to stereotyped play. In the short term they may save you time by avoiding theory, but in the long term I feel they'll hold back your chess progression.

Similar logic applies to choosing 1...e5 as black. You may find that you like other moves better. Just be sure you understand the reason behind your favorite move. For example, the Scandinavian (1...d5) may be an acceptable opening but it's not intuitively a good opening move. It violates basic opening principles, because after 2.exd5 Qxd5 your queen will be chased around, and with 2...Nf6 you are down a pawn. I now know that the Caro-Kann (1...c6) and French (1...e6) tend to result in a limited number of pawn structures that trap your pieces behind light-squared pawns, so I would steer away from those (my cautionary tale can be found in this post). However, if you understand those moves and like them, go for it.

To me, 1...e5 feels the best. It's good for the same reasons 1.e4 was: it contests the center, and opens lines for the development of the king's bishop (which will get you closer to castling) and the queen. Finally, it discourages an immediate 2.d4 by White. In any opening, if White gets two pawns at d4 and e4 without some serious concession it suggests Black was too passive.

I suspect a lot of readers are already familiar with this principle. After 1.e4, White wants to achieve 1.d4 to dominate the center, and Black wants to prevent it; after 1.d4, White wants to get 1.e4 in. Black would also like to achieve this, but it's less likely. Yet if you go over your games, I'm sure you'll find examples where after weak opening play these basic ideas are forgotten. I'm going to assume an understanding of the importance of the center in this post.

(Aside: At the time I write this, I am about two thirds the way through Marin's Beating the Open Games, which is a repertoire for Black after 1.e4 e5 and handles White's systems that avoid the Spanish before 4...a6 Ba4. This is hands-down the most instructive repertoire book I've ever encountered. It's so well written, and so objective, you could go a long way towards choosing your white repertoire by looking at what Marin considers the more difficult lines. My attitude towards some of these White options has changed from "boring", or "inferior but annoying", to "I wouldn't mind giving that a shot!" I'm looking forward to his sequel, which will handle the main-line Spanish portion of the repertoire. )

After 1.e4 e5, 2.d4 would produce the classic d4/e4 center, but it would be immediately destroyed, e.g. 2...exd4 3.Qxd4 Nc6, and so would be suspicious based on basic opening principles. So, what moves feel good here? At this point, you could see what the most popular moves at this point are to help guide you. For this demonstration I'll use Chessbase to see what the most popular moves are. References such as this, or your chess program's opening book, a one-volume book such as Nunn's Chess Openings (NCO), or whatever, are only being used as a guideline...they'll either confirm that your choice is playable, or serve as a warning that it might not be such a good idea. I made an opening book from the games of players rated 2400 or higher, to see what the "big boys" like to play. Here's the number of occurrences of the top 5 choices for White's second move:

Nf3 34110
Bc4 1054
Nc3 780
f4 565
d4 156

Again, realizing 2.Nf3 is the most popular continuation here is not earth-shattering in itself. Determining what's "popular" will be used for a couple reasons in my tutorial. Here, it's a tip-off as to what the "best" moves are and helping us to feel good about our choice. We're also going to use popularity to determine what the main lines are for our opponent so that we know which lines to learn first.

One notable exception from the above list is 2.c3. It's logical to think, "OK, I'm going to prepare d2-d4 by playing c2-c3 first". It makes sense. It can lead to a Ponziani-type opening, and was played by Morphy, but no GMs seem to play it. Let's say this was your favorite move at this point. You can either decide to make it your repertoire move, or you can try to understand why it's not popular. First, it moves another pawn instead of developing a piece, so on general principles that may not feel as good. Second, it now makes 2...d5 a decent move for Black, because after 3.exd5 Qxd5 the queen can't be harassed by 4.Nc3. In other words, c3 took away a natural developing square for the b1 N. So, you're letting Black get feisty in the center. If, after that explanation, you still like c3, then go for it...it was good enough for Morphy. If you progress to the point where your opponents are punishing you in the opening, you may decide that c3 isn't your favorite move after all.

Going through the other main moves: 2.f4 loses a pawn to 2...exd4. The King's Gambit is a real opening, but it's tactically complex and not a "common sense" opening. Odds are, if you were looking at the chessboard and knew nothing about openings, you'd consider 2.f4 a blunder (drops a pawn, exposes your king, and doesn't develop a piece). 2.Nc3 doesn't help you play d4, and doesn't get you any closer to kingside castling. Bc4 violates the guideline of developing knights before bishops. Of course, this isn't a guideline to be adhered to slavishly, but it's one that makes sense. Usually, it's clearer where you want to put your knights than your bishops, so it makes sense to delay it for a bit. Do I want to play the bishop to c4? b5? Let's see what Black does first. So, that brings us to 2.Nf3, the clear favorite. It develops a N, gets you closer to kingside castling, and supports d4.

Even if you're using a repertoire book for guidance, follow this thought process so that, at the very least, you've justified their move choice. If you think about the move for a bit, you're helping to transfer this move from short-term to long-term memory. I strongly recommend using an actual chess board, because I find it assists with this transfer.

This same technique of finding the move you like and checking it against the "book" moves is repeated until you've determined what your personal main line will be. For example, for Black we will see that by asking "if my opponent makes the most popular move, what do I want to respond with?" you can arrive at the Spanish main line of 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Bb7. I haven't actually settled on move 9 yet for my own repertoire, but Bb7 completes development (apart from moving the queen off the back rank) and is a good stopping point for these tutorials. This variation, if chosen, would be your foundation, your bedrock, your home turf, the trunk of the tree of variations. This is where you waggle your sword and proclaim, "NONE SHALL PASS!"


Just remember that it's sometimes appropriate to accept a draw as Black:



Back to our exercise in opening preparation:

2...Nc6 protects the pawn and develops a piece at the same time.

Now, if I were creating my own repertoire from scratch again, 3.d4 makes sense here. On basic principles, if pushing d4 is allowed it should be good. If Black exchanges the pawn on d4, a common pawn structure that results is called the "little center" by King and Ponzetto in their book on the Spanish, and is an example of what Kmoch calls a "jump formation":



This good for White because of the space advantage...White is less cramped and has a bit of an easier time than Black. This e4 vs. d5 center is a common feature of 1.e4 e5 openings in general, and explains White's advantage in many of the variations.

It is almost amazing how much of the theory of the Open Games can be figured out by just thinking about the center and the moves e4, d4, ...e5 and ...d5. In this case, following the basic idea of "if I can get away with d2-d4, play it!" results in the perfectly respectable Scotch opening. If you like the logic of 3.d4, and you like the pawn structures that typically arise in the Scotch, then go for it!

Back to White to play for their third move. 3.c3 would be the Ponziani opening. Theory would warn you that it's not the best choice, but it's playable. Here's a case where the guiding hand of theory might lead you to something "stronger", but if you absolutely loved it you could play it.

3.Bc4 develops the bishop to a nice diagonal and prepares castling, but it's less obvious how it addresses the center. It's not helping d2-d4, but it does help thwart d7-d5 and it also targets the sensitive f7 square. I choose 3.Bb5 because it develops the bishop and also weakens Black's control of e5. The latent threat is Bxc6 and Nxe5. This isn't possible right now (for example, 3...a6 4.Bxc6 dxc6 5.Nxe5 Qd4!), but the motif is there.

Black has many, many choices right now. Probably the most intuitive is 3...Nf6, which develops a piece, gets Black closer to castling, and attacks the e4 pawn. 3...d6 protects the e5 pawn and lets the queen bishop out. 3...Bc5 develops the bishop to a good diagonal before it can be imprisoned with d7-d6, and so on. My choice of 3...a6 is not the most intuitive, but it's the most popular. Here, rather than automatically play the "main" move, I've thought about it and have chosen it for my repertoire...I haven't had it chosen for me.

Here, challenging the bishop with ...a6 doesn't cause Black to fall behind in development (you can work this out for yourself). If White captures on c6, Black has gained the two bishops, and if White backs up (e.g. 4.Ba4) Black has turbocharged his queenside advance (...b5 will come soon). In this regard it has some resemblance to the Sicilian Najdorf. Often, wasting time in an opening by pushing a rook's pawn for no good reason is a waste of time (i.e. costs a "tempo"). Here, there are good reasons for pushing the rook's pawn. I am consciously violating a rule of thumb because there are concrete reasons to do so.

As White, I used to play the Exchange with 4.Bxc6 here. You give up the bishop pair but cripple Black's queenside majority. As someone who enjoys endgames,this sounded like a great idea, in theory... limit Black's choices, avoid theory, play positionally. Over time I found that I didn't like how my pieces coordinated, I didn't get endgames as much as I hoped, and most importantly I was missing out on the experience of playing against a variety of pawn structures. I prefer 4.Ba4 now. In both cases, I've said "this is the move that I like to play in this position", not "I don't like that book anymore, so I'm going to play something from this other book because I liked the blurb the publisher put on the back".

At this point, the main move is 4...Nf6, developing a piece, hitting the e4 pawn, and preparing to castle. I like that, so I play it. By the way, if you asked here or on the last move "is ...d5 possible?" the answer would be "not really", but you'll have to figure that out for yourself. Piket actually won a game with 4...d5 here against an IM, so it's not completely wacky, but you've been warned.

After 4...Nf6, White's e-pawn seems like it's in danger of being captured. As white, I currently play 5.Qe2 here to protect it. This is not the main move in this position, but the move makes sense (protects e4, develops the queen, vacates d1 for the king's rook) , and it's the move used in my current repertoire book. Remember: if you splurge on a repertoire book, treat them as menus of suggestions, not orders to follow. I may choose a move that the author recommends, or I may play something I like better. For example, I've gotten a lot of use out of Kaufman's repertoire book (there are very few books that provide white and black repertoires all in one volume) but I've rejected a lot of it for my own repertoire.

The standard move here is 5.0-0, and we'll see that 5.d4 is also possible. At this point there are a lot of move-order issues and unusual sidelines. In Part 2 I'll talk about how to navigate the maze that follows, and possibly help you come up with your own pet weapons to surprise an opponent.

Chess Tactics for Beginners Arrived

I finally picked up CTB, so I have something to smack around after CT-ART's done abusing me. Did the first 110 problems over lunch. I had an embarrassing think over one of the mate-in-one problems, an example of chess blindness if there ever was one:


The funny thing is, I knew the theme was queen mates in one, but I instinctively kept trying to find a longer sequence, or returning to a failed one, rather than focus on every possible queen move. I kept looking at the criss-cross "mate" with Qd5, thinking, "man I wish that were possible...wonder if the programmers made a mistake with this one." After about a minute of this I forced myself to actually think concretely and found the answer (which I'll leave to the reader to find.)

Really, really embarrassing. If this had been given to me as a "white to play and win" I may never have gotten it.
