D45 - Semi-Slav : Stoltz Variation

1.d4 d5 2.Nf3 Nf6 3.c4 c6 [I woke up about 10 minutes before 8 o'clock and didn't really feel like another QGA 3...dxc4 . I decided on the Semi-Slav last night actually because I'm sure it will be something we both will face v. the 1.d4, 2.Nf3 setup] 4.Nc3 e6 5.e3 [I know Kirk has no class as a chess player but I still thought he might try 5.Bg5 the Botwinnik system. I was flipping through an old TWIC and from 2000 i found a couple of games by Senff that went 5...dxc4 (5...dxc4 6.e4 b5 7.e5 b4?! 8.Ne4 Qd5 9.Ned2 c3 10.exf6 cxd2+ 11.Qxd2 gxf6 12.Bxf6 Rg8 13.Qc2 Nd7 14.Bh4 b3 15.axb3 Bb4+ 16.Kd1 c5 17.Bc4 Qh5 18.Qe4 Nb6 19.Qc6+ Bd7 20.Qxb6 Rg4 21.Rxa7 1-0 Gershon - Senff W Jun 2000) 6.e4 b5 7.e5 b4?! An inspired try! He scored ½/2 with it, but that's v. 2400 competition. I might give it a punt in blitz sometime. 8.exf6 gxf6 9.Bh4 bxc3 10.bxc3 Ba6 11.Nd2 Qd5 12.Bxf6 Rg8 13.Be5 Bh6 14.Bg3 Nd7 15.Be2 Bxd2+ 16.Qxd2 Qxg2 17.0-0-0 Qd5 18.Rhe1 Nb6 19.Qc2 Qa5 20.Bf3 Nd5 21.Bxd5 cxd5 22.Bd6 Bb5 23.Bb4 Qc7 24.Qxh7 Qf4+ 25.Rd2 0-0-0 26.Bc5 Rg2 27.Qh3 Rxh2 28.Qe3 Qxe3 29.fxe3 Rxd2 30.Kxd2 a6 31.Rf1 f5 32.Rg1 Rh8 33.Bd6 Kd7 34.Bf4 Rh7 35.Kc2 Kc6 36.Kb2 Kb6 37.Ka3 Rb7 38.Bd6 Bd7 39.Rg8 Kc6 40.Bc5 Rb1 41.Ra8 Re1 42.Rxa6+ Kb7 43.Ra7+ Kc6 44.Kb4 Rxe3 45.a4 f4 46.Ra6+ Kb7 47.Rb6+ Kc7 48.a5 Bc6 49.Ra6 Re1 50.Bb6+ Kd6 51.Ra7 Rb1+ 52.Ka3 Bd7 53.Bc7+ Kc6 54.Bxf4 Rb7 55.Ra6+ Kb5 56.Ra8 Bc6 57.Rc8 Bd7 58.Ra8 Bc6 59.Bg5 Rg7 60.Rb8+ Rb7 61.Rc8 Ra7 62.Bd8 Ra8 63.Rxa8 Bxa8 ½-½ Lopez Martinez - Senff W Jun 2000.

It may not be sound but it might be a switch from the usual Botwinnik stuff.] 5...Nbd7 6.Qc2 dxc4?! [Played because 6...Bd6 7.g4 is the Shirov-Shabalov Gambit which I have never liked from the Black side (or the White side particularly). I've never analyzed it. One of my Semi-Slav books gives 7...Bb4 as played by Kramnik against Gelfand with a nice game. The text was played back in the 1940s which is funny because after the game I commented that I was playing like a 1930s grandmaster.] 7.Bxc4 Be7 [Now I'm out of book. They have played 7...Bd6 ;
and the natural 7...b5 before. I had resigned myself to a quiet opening and wanted to see if Kirk could breach the defenses] 8.0-0 [8.g4 was maybe playable here if he had his heart set on a Shirov-Shabalov type position, but i think g4 is weaker with the pawn on e7 v. d6] 8...0-0 9.e4 c5!? I played this because in similar positions in the Meran proper e4 can be answered by c5. Unfortunately it wasn't an exact tranposition so i missed something 10.e5 Nd5 11.Bxd5 exd5 [11...cxd4 was okay here] 12.Nxd5 cxd4 13.Nxd4?! [The preparatory 13.Bf4 (holding on to the pawn AND developing) was required here] 13...Nb6 [I was worried about the position after 13...Nxe5 14.Nxe7+ Qxe7 15.Re1 but missed that after 15...Re8 16.f4 Qd7 His knight was hanging as well. I had resigned myself to the fact that I was going down material and didn't look hard enough. honestly though i was happy enough with my position. with the e-pawn gone i can actually get my pieces into play 17.Be3 Ng4] 14.Nxb6 [14.Nxe7+ the time here? 14...Qxe7 15.Nf3 looks pretty solid to me] 14...Qxb6 15.Be3 Bc5 16.Ne6! [I almost resigned on the spot, seeing that the rook was attacked by the bishop on the other end of the exchanges. I expected the pressure to build with 16.Rad1 . Then i collected myself and realized that it was just an exchange of pieces.] 16...Qxe6 [16...Bxe6 17.Bxc5 Rfc8 worked just as well. I knew he was gaining initiative and just wanted to hang on 18.Bxb6 Rxc2] 17.Bxc5 Re8 18.f4?! [I thought I was busted after 18.Bd6 ] 18...Qd5 19.Rfd1 Qc6 20.Rac1 Be6 Necessary because there was always an eventual threat of ...Rc8, ...b6 21.Rd6 [If 21.f5 Bxa2 22.b3 Rxe5! I missed that. I thought that I couldn't grab the pawn] 21...Qb5 22.f5 Bxa2 23.e6? [We both missed that 23.b4! was strong 23...b6 24.Qxa2 (24.Bd4 Bd5) 24...bxc5 25.e6 caused some troubles.] 23...fxe6 24.fxe6 [Fritz said that 24.f6 was better opening up the king] 24...Rxe6 25.Rxe6 [25.b4 was tricky again 25...Re2 26.Rd2 Rxd2 27.Qxd2 Be6] 25...Bxe6 26.Qe4 Qc6 27.Qf4 [I, of course, was hoping for 27.Qxc6 bxc6 and trying to ground him down on the sunny side of a (probably drawn) endgame. He, of course, wanted to keep as much material on the board] 27...Rc8 28.Be3 Qe8? Throwing away any slight advantage I had 29.Rxc8 Qxc8 30.Bxa7 I totally missed, like Kirk 10 moves earlier, that this pawn was hanging. 30...Qd7= Game drawn by mutual agreement That was a quick draw in the big picture, but it seemed like more than 30 moves to me. Opposite colored bishops, symmetrical pawn's a draw. And I think it's the first half point I've nicked off Kirk as Black since we started. ½-½

December Training (3), 17.12.2005

It is very important I think for Craig and I to continue to play these games each Saturday morning as this is the majority of the chess study I get during the week. Concerning the game, I was seriously hoping that Craig would give me a Benko (since he randomly mentioned that he'd like to play it this week), but I got what I wanted out of the opening: the initiative and a material advantage. I continued to try to play sharply and ended up "sacrificing" two pawns in the middlegame. I regained my last pawn and Craig offered a draw and I accepted.
1.d4 d5 2.Nf3 Nf6 3.c4 c6 4.Nc3 e6 Craig always encourages the Botvinnik System (see Topalov-Kramnik for more details).
5.e3 Nbd7 6.Qc2 dxc4!? [Craig knows that I play 6...Bd6 7.g4! (the Shirov-Shabalov gambit which leads to a whole bunch of complications immediately for both sides). Craig takes me out of book right away. I decide to play the Semi-Slav the traditional way: always setup for the e4 push.]
7.Bxc4 Be7 [Craig had in his mind to push .. c5 in order to get some freedom for his pieces. If he plays the traditional 7...b5 8.Bd3 Bb7 9.e4 Craig's position won't be worse, but his pieces are really tied up.]
8.0-0 0-0 9.e4 White now has a wonderful aggressive position. All of White's pieces are free to work now.
9...c5 10.e5 [I couldn't play 10.dxc5 Bxc5 11.e5 Ng4 12.Qe4 Nxf2 13.Rxf2 Bxf2+ 14.Kxf2 Qb6+ with major complications. The text forces the issue, but White now has to be careful to support his d4-pawn.]
10...Nd5 11.Bxd5 exd5 12.Nxd5 cxd4 13.Nxd4 [A simple move that was missed. After 13.Bf4! it's impossible for Black to immediately regain his pawn. Look too at how well White's pieces are setup as compared to Black's.]
13...Nb6 [I'm not sure why Craig didnt' play 13...Nxe5 This is a terribly complicated position I'd say (that being that pieces are hanging for both sides like crazy) and perhaps that's why. But after 14.Nxe7+ Qxe7 15.Re1 Qf6 16.Qe4 Bd7 (16...Re8? 17.Bf4! with the threat of back rank mate) 17.Bf4 and although it looks bad, the simple 17...Nc6 takes care of everything. Calculating lines deeply is something that we both need to work on.]
14.Nxb6 [I turned down 14.Nxe7+ because I felt that with the Queen on b6 instead of e7 that there'd be a better chance of me hanging onto the weak e5 pawn.]
14...Qxb6 Of course I forget that now he is threatening my Knight, so I can't play the simple f4 and hang onto my pawn forever.
15.Be3 Bc5 16.Ne6 [I didn't want to get into 16.Rfd1 Rd8 (16...Re8) 17.Nc6 Rxd1+ 18.Rxd1 bxc6 19.Bxc5 which I can see now is very good for White, but at the time thought that with one small misstep that would be it for me.]
16...Qxe6 17.Bxc5 Re8 18.f4 Qd5 19.Rfd1 Qc6 20.Rac1 Now Black is really on the run.
20...Be6 21.Rd6 Qb5 22.f5 [This is where my game falls apart. I should keep attacking! 22.a4 Qb3 23.Qxb3 Bxb3 24.a5 Be6 25.b4 and White goes into the endgame with a strong advantage.]
22...Bxa2 23.e6? [I saw things that weren't there (just like last game). I missed that the Bishop was on the diagonal (just like I missed on the previous move that the Bishop was attacking a2. 23.b4 b6 24.Qxa2 bxc5 25.e6! fxe6 26.bxc5 Qb4 27.fxe6 This was the type of position I was envisioning when I played e6. One move too soon though.]
23...fxe6 24.fxe6 Rxe6 25.Rxe6 Bxe6 26.Qe4 Qc6 27.Qf4 Rc8 28.Be3 Qe8 29.Rxc8 Qxc8 30.Bxa7 Qd7 Craig said he missed the Bxa7 (which is fair as I missed a lot too) and offered a draw too. Black's first half point in a long time. Good game. ½-½
