My first attempt at a chess post:
For a little context on my skill level, I'm not rated. I only started working on chess 'seriously' a few years ago. I mostly screw around playing 3 minute blitz games on Yahoo! chess. My 'rating' there varies from 1500-1700 depending how tired I am when I play. Based entirely on blitz this nothing like a real rating. I've out-blitzed my share of players with real 1800+ rating on a good day, but it's not the same as real chess. I need to slow down if I want to improve... but I'm only playing for fun and I get a lot of joy out of the fast games.
Earlier today I ran into a player with the handle "schach_radfahren_wandern," a German I'm guessing. His/her Yahoo! rating was just below 2000, a higher class of player than I usually run into. I lost a few games to this player but won what I feel is one of my better 3 minute blitz games against him/her. I think you'll find it surprisingly clean for such a fast game. I made a few errors which I'll point out. My opponent made a few bad moves which I'll also mention.
I've attempted to use ChessPublisher's java applet (we'll see how that goes,) and I can't be too wordy in it or it crashes (probably a good thing.) So here's a bit about the game the annotations won't explain.
About the opening, the Benoni is named from the Hebrew 'Son of Sorrow.' According to wikipedia this name is a jab at the black pawn structure:
http://en.wikipedia.org/wiki/Benoni_Defense "The often weak black pawn on d6 gave the name." but Wikipedia is
wrong. Benoni was the name of Aaron Reinganum's 1825 manuscript on the line. He analyzed these positions when he was depressed, sublimating the bad feelings into something productive (the chess book,) so it made perfect sense to call the finished work 'Ben-Oni' the 'son of (his) sorrow.'
About the move order, I like 1. d4 c5 (the 'old' Benoni) best because it gives white more opportunities to go wrong. If white takes the c pawn of course he can't keep it, and that gives black a central majority. The main problem with the 'old' move order is the Taimanov variation which only occurs if black goes for the 'modern' setup. (modern in this context doesn't mean 'contemporary' so much as 'anti-classical,' contemporary players play more classical systems than modern ones except for Indian defenses.) I like the super-closed Czech Benoni with e5 so the bishop check is not a problem. I got a lot of good theory on the Czech Benoni from Andrew Martin's excellent Fritz Trainer DVD, btw. I recommend it. By no means am I parroting any of his analysis here, but the way I play these kinds of positions the way I played this game has been heavily influenced by his discussion of them. When you can take the *ideas* from a work and apply them to similar positions you know the work has taught you something good.
About the game, I'd love to see 4. dxe6 when I could recapture with the f-pawn and get my central majority that way (it's hard to believe, but people play this line against me all the time.) White wisely avoided that continuation and played the main line instead. When I play 7 ... Nf8 Fritz 9 (chess software) wants to say "black has a cramped position." I don't think Fritz understands this position very well. Closed positions like this are difficult for computers to asses because the plans for both sides are deeper than most computers' horizons. That knight is going to g6 to serve the important function of clamping down on f4. This is the way Nisipeanu plays the Benoni and gives black excellent kingside chances. (See the first sideline in the game.)
For move 10 we have to talk about closed positions and pawn breaks. With the closed center each side wants to make favorable pawn breaks. Black wants to play b5 or f5 if he can. White, likewise wants to prepare and play b4 or f4. However white needs more preparation to play f4 than he takes here. Playing f4 this early frees up e5 for my knight. In a perfect world, once I have a knight on e5 I'll never let go. Black's powerful central knight will rule the game. (In this game I put the wrong knight on e5 first, and lost contact with that square for a while... it was a 3 minute game after all.)
For 27. we must discuss good and bad bishops in closed positions. White's pawns are locked on light squares and his white square bishop is stuck behind them... it's movement is incredibly restricted... it's little better than a pawn. We call this a 'bad bishop,' white should be trying to exchange this piece off. White's dark square bishop, on the other hand, has free run of the board. We call this a 'good bishop,' it's not only mobile, but it control the important dark square 'holes' between white's pawns. White wants to hold on to this piece at all costs. Of course I should have taken it back on move 11, but when white gives it up on 27 it's an important turning point. Sure, he gets rid of my monster central knight, but I still control e5 with a bishop. After that exchange my dark square bishop is developed *outside* my pawn chain. It's not a 'bad' piece anymore, but very powerful now that white's dark square bishop is gone and it controls the 'holes' between white's pawns. White had to do something to get rid of my powerful central knight, but he'd have done better to trade his knight for it or not to have played f4 so recklessly in the first place.
It isn't until 28 when Fritz (finally goes over the horizon and?) says black is clearly winning. Here black connects the rooks and makes mate threats with the queen. I don't know if white could have done better with his queenside counterplay (the one concrete move Fritz suggested which I included in the sidelines doesn't look like much to me,) could have done better to keep my knight off e4 when I lost contact for that minute back there, or if Fritz is just misunderstanding the closed position that badly and doesn't 'see this continuation coming' until just now. White has a space advantage, but black's pieces are more mobile than white's. Black isn't cramped.
33... the sacrifice. Fritz wants to give this move an '!' meaning it's a good move that isn't obvious. It is obvious, though, to any attacking player. As I annotated, I spent only about half a second on that move. When you play too much blitz as I do you get an eye for these patterns. This sacrifice gives me control of all the 'flight squares' around the white king. It puts the king under 'house arrest,' (he can't go anywhere,) and sets up mating threats all over the place. What's more, all of white's pieces are pinned and tangled up. Even if there isn't a forced mate (which there is, but I didn't stop to calculate it out) it's easy to see black can regain the material by force. (I ended up missing the mate and going for the material ... greedy me ... it was a win either way, but the check mate would have been more stylish... of course white let me checkmate a couple moves later, but that was a blunder. ... the very end is pretty much the messiest part of this game... we were both in time trouble by that point. I don't think the rest of the game is at all bad. Like I said, it's a 'pretty good' blitz game, IMO.)
And without further ado, I'll attempt to post the game. Keep in mind (especially when I put the wrong knight on e5 and miss the checkmate combination choosing a much longer winning line istead) each player had exactly 3 minutes to make all of his/her moves. This game went by
fast.
