re:please analyze (round 3; 4 hour game) - 2006/11/30 22:36
Be aware of transpositional possibilities. Black wants to play e6 in this position, but doesn't want to saddle himself with a bad bishop. Be2 first forces him to develop in a slightly more awkward way.
I'm no expert on this line, but this bishop maneuver seems wrong on general principles to me. You move a piece twice only to trade it for one that's moved once, developing his queen in the process. Furthermore, you have more space, which means you want to avoid trades unless you get something ni exchange for them.
I would have considered b3 and Bb2, instead-- although, as I said, I'm not really an expert in this line.
An obviously, things would be different if you haven't made that exchange, but it's easy to see how having the bishop on b2 might be nice in a position like this.
I think 12.Re1 makes more sense here, setting up some latent pressure against the queen in the event you push the pawn to e5.
This move strikes me as unneccesarily passive. You're decentralizing your knight--at with the relative paucity of black pieces on the kingside, I think you should be exploring aggressive options over there.
14.Ne4 attacks the queen the same way but does it while improving the position of your N.
My computer prefers Nb3, of course, but I just don't see what plan it's a part of-- the night doesn't seem to be doing anything over there after the one-move threat is disposed of-- and you knew your opponent wasn't going to hang his queen!
I don't understand this move, either. Nb4 wasn't much of a threat, and black's already indicated he's not that interested in Qb4. Plus, now, your knight is a little looser. I know a lot of players who would start looking for combinations based on that knight at this point.
This seems like a very passive choice of queen retreats. Granted, Qc2 loses a pawn, but it's situations like this where you really have to look, hard, for alternatives. And it turns out you have one, based on the position of the black queen and the lose Bh4.
16.Nfd4! stays in the game. After this move black is better.
And now you go from slightly worse to losing. The move you choose here has nothing to do with black's threat (to win the b2 pawn). You don't have a lot of great options here, mind you, as a result of your passive earlier play, but I think Nc5 was best, counterattacking.
Worse than losing the pawn is, I think, the fact that you're making your knight's position worse. I mean, you could deal with losing a pawn if you were getting some activity for it, but this piece is the worst minor piece on the board. (Even the b6 knight--and that's usually a bad square for a knight--is tying down one of your rooks to the defense of a pawn.)
later, you forget that the bishop is attacked.
This isn't an uncommon mistake to make. Until you get to a point in your thought process where you don't make it (where you can get by being very methodical-- also make a conscious effort to look at which of your pieces are attacked) I always feel that moves like this--that lead to the error even if they aren't technically incorrect, get a ?!. Why put yourself in a position to make a big mistake like that?
That being said, I think you need to think through this before. In your last game, I pointed out how your opponent made a big mistake by doing what looked like a "don't know what to do so I'll attack something" move. I think you might be doing the same thing. Although you set a nice trap, here, you will quickly learn that traps don't work! 9 times out of ten, your opponent will see them coming.
So the question is-- and you need to be asking yourself at this point, if you aren't already-- "what great thing does this move do for my position, assuming my opponent doesn't grab the poison bishop?"
And here, I think, a little bit more patience was required. You're still in trouble, but the Nh6+ threat isn't giong anyhere. So why not play Re1 first, improving the position of your rook. You're going to need all of your pieces to win, and the ability to add firepower down the e- and f- files (Rc3-f3) could create a lot of opportunities for you.
Now, of course, given that it looks like you missed a winning tactic on your next move, you might throw all this out the window, but the general idea is very important: if you don't see a winning tactic, try to find ways to improve the position of your piece which contributes the least to the attack.
I agree what Bxf7 wins. Some of the tactics get pretty complex, so I wouldn't beat yourself up for not seeing them (the main line goes
25.Bxf7 gxh6 26.Bxe6 Nd7 (providing an escape square for the king on c7)
27.Qg8+ Ke7 28.Qf7+ Kd6 29.Rd3+ Kc7 (...Nd4 Rfd1) 30.Rxd7+ regaining the piece with winning attack is the line if black takes the sacrifice.
It's worth asking yourself why you didn't see this. With your queenside in shambles, winning a pawn here is not enough-- what did you think you were going to get after Nxf7?
Up until this point I think you've done an admirable job down a rook, but I don't like Qh3. You're putting your queen on a really passive square.
At this poing I'd be seriously considering the endgame. I don't think it's a gimme for black in view of your extra pawn and well-placed knight. Certainly it's got good swindling chances.
Do I think it's lost with best play? Yes. I do. But I suspect that with moves like Qh3 you're only going to find yourself going into the endgame under less favorable circimstances.
And I think that h5 probably counts as one of those "hmm, don't know what to do so I'll attack something" moves.
Black bails you out, here, although his exchange should still prove sufficient to win. Obviously, he should have played Qxe6 here after which my prediction about entering the endgame on less favorable terms would have come through.
I think keeping the rooks on is more valuable than winning the pawn.
Think of it this way: when he's got two rooks on the board, that's twice as many rooks you can snare with a knight fork.
As always, I make oodles of mistakes in my own games, probably missed somethign obvious here, yada yada yada. I make no claims about discovering "truth" here-- just my quick thoughtson the game..
