I Love/Hate Speed Chess…

by admin on May 22, 2013

… and the reason I love it is that speed chess is ridiculously entertaining.

… and the reason I hate it is that speed chess magnifies all of my worst tendencies.

Both of these reason were on full display in a mind-boggling speed game that I played with Linnea yesterday after the Aptos Library chess club was over. Here is the position where the mind-bogglingness started. I’m playing Black, Linnea is White, and it’s my move.

Position after 1. g3. Black to move.

FEN: r2q4/2p3k1/pb4r1/1p1pP1pp/3P1pnp/2PQ1NP1/PP3P1N/5RRK b – - 0 1

Up to this point I’ve been having a merry old time pushing all of my kingside pawns, but after Linnea’s move 1. g3 I started to get a whiff of trouble in paradise. On any pawn capture, the lines start opening up in an uncomfortable way around my king. And the knight on g4 is just in the way, making it hard for me to avoid the pawn captures. Is there anything I can do about this?

Here I found what Rybka says is Black’s one and only correct move: 1. … Nxf2+! According to the computer, Black is now +1.9 pawns, and on any other move I would have been 0.0 or worse. So, huge props to me, right?

Well, not so much. The problem is that after finding the only way out of trouble (temporarily), I didn’t think very hard about what got me into trouble in the first place. I played the next couple of moves on auto-pilot. Linnea played 2. Rxf2 g3 3. R2g2! and now we got to the most crucial position.

Position after 3. R2g2. Black to p lay and lose.

FEN:r2q4/2p3k1/pb4r1/1p1pP1pp/3P1p2/2PQ1Np1/PP4RN/6RK b – - 0 3

John Emms’ The Ultimate Chess Puzzle Book has a great chapter called “Find the Wrong Move!” This chapter is full of positions where somebody plays a move that seems completely natural and plausible, and yet is practically the worst move on the board. The above position would be a perfect one for that chapter. Find the wrong move!

We were playing speed chess, remember. So I gave this position about 5 seconds thought, if that much, and played 3. … gh?? The “automatic recapture.” The only reason I even thought that long is that I had to check and make sure I wasn’t getting mated after 4. Rxg5. (I’m not getting mated because I play 4. … hgQ+, queening with check and removing the guard all at the same time.)

What I missed is that Linnea can simply recapture on h2: 4. Rxh2! At this point my reaction went through the five stages of grief.

Denial: Okay, she’s threatening to take on h5 and she’s threatening to take on g5 and she’s threatening Nh4 (the real killer), but surely I can do something about those things, right?

Anger: This is ridiculous, how could I be losing this game? I’ve been winning for like 20 moves, and now all of a sudden there’s nothing I can do?

Bargaining: Okay, how about if I give back a little bit of material. Say, … Qd7 or … Qh8?

Depression: I have got to be the worst speed chess player in history. How can I pretend to be a “teacher” when I do things like this?

Acceptance: Oh well, it’s only speed chess. I played 4. … Kh6 5. Nh4 Rg8 6. Nf5+ and resigned.

The computer, of course, doesn’t go through the five stages of grief. Rybka simply says that after 4. Rxh2 White stands at +1.8 pawns. That’s right, one “automatic recapture” transformed the position from 1.9 pawns in Black’s favor to 1.8 pawns in White’s favor. Rarely have I ever seen a position where the seemingly obvious move was so radically, outrageously wrong.

As I drove home in my car, it hit me that of course, there was no need for me to take the knight. It’s not going anywhere. I could have played 4. … g4, which puts another knight under attack and, more importantly, clears a path to h4 for the queen. It’s critically important for Black to keep the four pawns on the board until he can bring up reinforcements. In particular, the g3 pawn is a monster that paralyzes White’s whole army. This pawn is worth more than a knight.

The tactical details after 4. … g4 are quite complicated and I could give my analysis here, but I think that would kind of miss the point.

In order to learn from this game, we need to ask not, “What can Black do better after this point?” but “What did Black do badly before this point?” Look at those queenside pieces. The queen has never moved. The queen rook has never moved. The dark-squared bishop might as well be a pawn, for all the effect it’s having on the game. Black is trying to attack with three of his pieces as bystanders. This is not a good idea.

Lesson 1: Invite all of your pieces to the party. Don’t launch an all-out attack until you have completed your development. The price of this failure became apparent after 4. Rxh2. I’d like to move my rook to h8 or my bishop to d8, but those all take two or three moves and I don’t have that much time. The time to improve those pieces was earlier.

In fact, the same thing is true for the position after the supposedly good move 3. … g4. It’s actually quite debatable whether this is Black’s “best move,” as Rybka says, because it doesn’t actually solve the problem of the bystanders on the queenside. The position remains quite perilous, where one misstep for Black can easily turn his won position into a lost cause. For this reason, I think that the best move is actually Rybka’s second choice, 3. … Qe7 (which it rates at +1.7 for Black). Black’s plan is simply to prevent any breakthroughs with e5-e6, develop his queenside pieces, and only then start to march the kingside pawns again. If White wants to move her knight away from h2, let her do it. Once Black’s pawns have pieces behind them, White will not be able to stop them without sacrificing some material.

This is the practical, sound way to play the position. It carries very little risk of disaster. It’s Mike Splane chess. Even though he’s very good at tactics (see my last post!) he is always in favor of having the tactics flow from a sound strategy. I can almost hear him saying, “To win a won position, first eliminate all of your opponent’s chances of counterplay.”

As I said at the outset, speed chess magnifies all of my bad tendencies. Here’s what I did wrong in the game: I launched a pawn storm prematurely. I didn’t develop all of my pieces. I had “tunnel vision,” focusing only on the kingside and forgetting the rest of the board. I played an “automatic recapture,” without even thinking about my opponent’s response or other options for me. (In fact this is important enough for me to make it another lesson:

Lesson 2: There are no automatic recaptures.)

Immediately after the game I was stunned by the fact that my position had gone from won to lost in the blink of an eye. But once you look at the position from the perspective of the whole game, you realize that I had sown the seeds of my defeat much earlier. They were all there, waiting to bloom like a huge carrion flower.

So speed chess is frustrating. But it’s also ridiculously entertaining, I’ve got to admit.

By the way, I’ve scarcely written one word about Linnea, and that’s unfair. She made mistakes, obviously, but on the whole she played more practically than I did and deserved to win. Notice how in the initial position she has invited all of her pieces to the party, even if the knights are looking somewhat forlorn. (That was her biggest problem in this game, figuring out what to do with the knights.)

Linnea will be playing in the “Best of the West” open this weekend in Santa Clara, a big tournament with a whopping $1500 prize for first in the 1300-1499 section. I am super-optimistic about her chances. I mean, she’s beating masters in speed chess. (Not just me, a poor speed chess player. She also beat Gjon, an excellent speed chess player, in one game this weekend.) The challenge for her is the opposite of mine; she hasn’t yet learned how to use the extra time in a tournament game effectively. But she will!

Simultaneous queen sacs!

by admin on May 21, 2013

Last weekend Mike Splane showed me a sensational game that he recently played at the Kolty Chess Club. It features a position where his opponent could have played a queen sacrifice, to which the best defense would have been a counter-queen sacrifice! The only slight blemish on the game is that Mike did not see his opponent’s threat. He was just lucky (sort of) that his own threat was faster. “Sometimes being a doofus is good!” he joked.

Let me back up to a move before the critical position. Black has just played 1. … Rc4, and it is now Mike’s move. (Unfortunately I don’t remember what his opponent’s name was.)

Position after 1. ... Rc4. White to move.

FEN: 5rk1/R3Rp2/4p1p1/1q1pP2p/2rB1Pn1/1pP3P1/1P5P/3Q2K1 w – - 0 2

It looks to me as if White can win a pawn in complete safety with 2. Reb7 Qc6 3. Rxb3. However, Mike thought he saw something better. And in fact he was right–it was better, only there was a little extra wrinkle that he hadn’t counted on.

The move he played was 2. Qd3!, which makes a drastic threat: 3. Qxg6+! forcing checkmate or winning a ton of material. What he hadn’t realized was that Black very nearly has a spectacular answer of his own.

Position after 2. Qd3. Black to move.

FEN: 5rk1/R3Rp2/4p1p1/1q1pP2p/2rB1Pn1/1pPQ2P1/1P5P/6K1 b – - 0 2

I’m not quite sure how to caption this position. Black to play and almost draw? Black to play and scare the bejeezus out of his opponent? Anyway, can you see what Black’s idea was?

The answer is that Black can almost play 2. … Rxd4!?, simultaneously offering a queen sacrifice and an exchange sac. White is ill-advised to accept either. If 3. Qxd4 then 3. … Qe2 is winning for Black — not only because of the danger of … Qxh2+ but also because the b2 pawn is hanging. And if 3. Qxb6 Black has a remarkable drawing variation: 3. … Rd1+ 4. Kg2 Rd2+ 5. Kf1 (if the king goes to either f3 or h3 he gets mated!) 5. … Nxh2+ with a perpetual check. This is a great position to know, and in fact I mentioned it in my recent post Questioning Assumptions: rook and knight against a king on the edge of the board can often draw all by themselves.

As it turns out, White actually does have a way to thwart this combination. After taking the queen with 3. Qxb5 Rd1+ he can give it right back with 4. Qf1! Then Black’s best move is 4. … Ne3!, leading more or less by force to the following line: 5. Qxd1 Nxd1 6. Rab7 Nxb2 7. Rxb3 Nc4. (Diagram)

Position after 7. ... Nc4. White to move.

FEN:5rk1/4Rp2/4p1p1/3pP2p/2n2P2/1RP3P1/7P/6K1 w – - 0 8

This is actually a pretty interesting endgame position in its own right. Mike thought that Black might actually have a “fortress,” but I don’t think so. To create a fortress, Black really needs his knight to be on e4, but if he goes there the knight will be subject to undermining with c3-c4. Still, it will be a long and agonizing struggle for White to win this game.

But anyway, this is all moot, because in diagram 2, after 2. … Rxd4!? White would play 3. Qxg6+!! and win. That’s what I started this post with–defending against a queen sacrifice by a counter-queen sacrifice. Note also that if Black declines with 3. … Kh8 White continues 4. Qxh5+ Kg7 5. Qxg4+, getting rid of the knight, after which he can take on d4 without any fear of getting checkmated.

Black saw this, and instead of the failed brilliancy of 2. … Rxd4, he played 2. … Kg7 to defend his g-pawn. But now his kingside collapses around him. 3. Rxe6! takes advantage of the pin on f7 and threatens Qxg6+, so Black still doesn’t have a chance to play his queen sac. Black defended with 3. … Kh6 and now Mike offered a rook sacrifice with 4. Rxf7! Once again this forestalls Black’s dreams of sacrificing his queen, because mate is threatened on g6. Black continued playing forced defensive moves: 4. … Rg8 5. Ree7 Rh8 6. e6! (diagram)

Position after 6. e6. Black to move.

FEN:7r/4RR2/4P1pk/1q1p3p/2rB1Pn1/1pPQ2P1/1P5P/6K1 b – - 0 6

With threats like Bg7+ and Bxh8 in the air, it’s all over. I’m not sure whether Mike’s opponent played on a couple more moves or resigned here, but in any event the result was 1-0.

A pretty cool finish! I have one remaining challenge for the reader: Can any of you find an actual tournament game where one side plays a queen sacrifice, and the only way for the other player to avoid defeat is to play an immediate counter-queen sacrifice that wins? I’m sure that it must have been done, but I can’t think of one off the top of my head. This position is not quite an example because Mike’s queen sac idea 3. Qxg6+ avoids a draw, not a defeat; and maybe he could have won anyway with the 5. Qf1 idea that led to diagram 3.

Questioning Assumptions

May 8, 2013

In my last post I wrote about one of the most ubiquitous kinds of mistakes, in life as well as chess: the kind of mistake where you assume you know what is going on, and the assumption seems so obvious to you that you aren’t even aware of making it. Here’s a nice chessboard example [...]
