Welcome to Chess Theory and Annotations!

I am not well informed as to whether there are other chess blogs out there, nor their quality, so I wish to invite you to enjoy this blog without raising your expectations of what to find here. I am a relatively strong chess player, mostly because I enjoy the game and as such spend a good deal of time with it. Yes, I do play a good deal, but that is neither here nor there, since generally speaking I do not care to impress people with my chess playing ability (over the board I am much more concerned about winning a good position or trying to hold a bad one than impressing the audience, which is just as well since there isn't one.) Rather the purpose of this blog is to share my annotations, as well as my theoretical understanding of the game, and some modest amount of opening theory. The reader here may or may not find this information instructive as the majority of it is created entirely as a by-product of my enjoyment of the game of chess, and is shared simply with the feeling that someone else may enjoy it. That being said, feel free to make requests, but understand that I will feel free to decline them.

Leonid Stein--

Having recently run across a fascinating game of Stein's in Garry Kasparov's excellent book On My Great Predecessors, Part III, namely his game with Paul Keres in the twelfth round of the 1967 Moscow international tournament, which is at this moment my favorite game of all time, I have decided to take a look at some of Stein's games and see what other enjoyable moments he has provided those who care to look for them. I began this inquiry simply by searching for Stein in the Fritz 10 database, and I found the following game to be of interest--it demonstrates a truly profound understanding of the game--with great precision Stein obtained a dominating position in which white sought salvation in vain by exchanging his queen for two minor pieces.

I apologize for the presentation of my annotations, until I figure out a better way to do this I am simply going to cut and paste in a pgn file, in the hope that the readers with a pgn viewer can simply cut and paste it into a text file, and then save it with a .pgn extension, and that those with a board and pieces can follow along on the webpage as the pgn format is rather human readable, with the exception of the punctuation after the moves (!, !?, etc.), but moves with these marks usually have descriptions after them. In any event, I will try to fix this, and if any one has any ideas on how to make this easier to use for people trying to read it please let me know.

White should probably over protect the e5 pawn, and try to get theb1 knight to e4. Since black's counterplay does not have any obvious targets,he should probably decide on moves which promote counterplay and hinderwhite's chances of exploiting the holes in his kingside (e4, and thedarksquares around the king.}) 9.

Nf1 {better to eat crow and play exd5, with a somewhat inferior game butat least the rook would stand on an open file where it could hopefully tradeoff one of black's rooks.} d4 {black's last few moves have deftly exploitedwhite's slight inaccuracies with Nd2 and his failure to trade off a pair ofpawns in the hopes of trading off a pair of rooks. Had the knight notretreated to f1 it could now hop to c4.} 12. c4 $1 {the worse move imaginable,except for all the other moves. there was no other way to save both the d3and c3 pawns. maybe white should have sacrificed one, however, since now heappears to be practically down a piece--but it would be awfully depressing toaccept the loss of a pawn--and with it an invasion of black's pieces, early inthe game and from the white side of the board and then hope for salvation inthe ending. The bishop may be freed someday by bringing it to d1, but it isthree moves away, since the queen will have to vacate the square, so blackwill be essentially a piece up for quite some time. The bishop may also dosome menial work by defending the d3 pawn from b1 or c2, should it come underattack while white's queen is away, and the closed nature of the game meansthat the loss of a few moves may not be devestating, so white was probablycorrect on both a logical and psychological level to prefer the temporaryimprisonment of the piece to the permanent loss of a pawn.} e5 13. Bd2 Bc8 14.Ng3 a5 $5 {not bad but very commital. for the foreseeable future breakingopen the queens wing would probably help black, but apparently he is planningon throwing everything into a kingside attack, which is justified by the factthat he is essentially up a piece, especially on that part of the board. Thethreat of b4 is more or less neutralized forever, and the black rook gains thea7 square (which might help it swing into the attack more quickly, though thisisn't used in the game), at the cost of any hope of developing an initiativeon both wings.} 15. Bb3 Bg4 16. h3 Bxf3 $5 {this move is rather surprising tome, The bishop seems to be a dangerous attacking piece, especially consideringthe weakness on h3. The queen was going to have to vacate d1 at some pointanyway, since that is the only way white can get his king's bishop back intothe game, so this move does not even really gain time. It is true that thisis something of a necessary link in the ingenious maneuver which follows. Thereal justification is that the additional knight on the kingside has givenwhite additional defensive resources when compared to a king's indian. Merelybeing a good attacking piece is not enough when white can challenge black onthe kingside, in particular the h5 square being under attack from the knightis surprisingly significant. e.g.} (16...

Kh8 19. h4Ng8 20. h5 Bh6 {with some advantage to black, but it is hard to say it is morethan in the game.})) 18... f5) (16... Bc8 {doesn't really change anything, only now the rook on a8 comes into play via a7.} 17. Qe2 Qe8 18. Nh2 f5) 17. Qxf3 Kh8 $5 {this is an interesting maneuver! Stein want's to exchange off the dark square bishops, when his knights shouldbe able to outplay white's bad bishop and knight in either an endgame or amiddlegame.} 18. Bd1 Ng8 19. Rf1 Bh6 20. Be1 $6 {the previous notnotwithstanding, now black's "bad" bishop is a stronger piece than white'sgood one.} (20. Qe2 {seems stronger--white prepares Bxh6 and Qd2, finallyfreeing his light square bishop.}) 20... Qd7 21. Qg4 $6 {why force lose atempo to f5? isn't black going to play this anyway? the immediate b3, inorder to play Ra2 and let the queen's rook get into the game seems preferable.}f5 22. exf5 gxf5 23.
