return of the caro

January Match Internet Chess Club (8), 24.01.2006
B12 - Caro-Kann : Advanced Variation

We decided to have a midweek game. 1.e4 c6 I wanted to move the battle to the late middlegame/endgame. Over the board there won't be as many miniatures for and against I hope 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 c5!? [I tried something different today. Normally I play the Karpov-esque 5...Ne7 6.-- Nd7 and only then 7.-- c5 and 8.-- Nc6 . ] 6.0-0 Nc6 7.c3 Nge7 [The main line is 7...cxd4 8.cxd4 then 8...Nge7 but I didn't want to open any lines for him. I can't understand why someone would play this way v. the old Karpov Knights way. Development is awkward at best and painful at worst.] 8.Bg5!? [The mainline is 8.dxc5! Ng6 9.b4 Ngxe5 . I wa happy with his move because it allowed me to develop a little bit] 8...Qb6 9.Qb3?! giving himself doubled isolated pawns [9.Qd2 may have been better] 9...Qxb3 10.axb3 Bxb1 11.Rfxb1 cxd4 12.cxd4 Nf5

Whether I'm better or worse here I'm happy with my position. I missed Kirk's next move, but I wanted just to trade off the bishops and my two queenside pawns are better than his. 13.Bb5! Be7 14.Rd1 Bxg5 15.Nxg5 h6 [I wanted to play 15...Ke7 to break the pin, but after an eventual 16.Nf3 -- and 17.g4 the knight is out of play] 16.Nf3 0-0 [Now 16...Ke7 17.Bxc6 bxc6 18.g4 loses] 17.Bxc6 bxc6 Now it comes down to whether the backwards c-pawn is weaker than the doubled isolated b-pawns. 18.g4 Ne7 19.Rdc1 [Fritz liked 19.Ra3 and I think that's okay as well. Easier for him to get at the a-pawn, since my knight is guarding the c-pawn. ] 19...Rfc8 20.Ne1 Ng6?! [Fritz wanted me to go after the b-pawn, but my idea was to play 20...Rc7 defending the a-pawn 21.-- Rac8 and freelance with my knight. With this setup of rooks if he decided to go after my a-pawn, i can always play 22.-- Ra8] 21.Ra6? [I think 21.Nd3! was better, limiting my knight.] 21...c5! 22.Nd3? [22.Rxc5 Rxc5 23.dxc5 Nxe5 24.h3;
or 22.dxc5 Nxe5 23.h3 was better] 22...cxd4 23.Rxc8+ Rxc8 24.Rxa7 Rc2 25.f4 Rd2 26.f5 Rxd3 [Fritz said that 26...exf5 was stronger but I thought my line was winning as well] 27.fxg6 fxg6 28.Rb7 Re3 29.b4? [29.Rb4 may have been a bit better, but it's a win now] 29...d3 30.Kf2 Re2+? [a blunder by me 30...d2! was instantly winning] 31.Kf1 Rxb2 32.b5 Rxh2? [Again not paying attention. I got lazy 32...Rb1+ 33.Kf2 d2] 33.Ke1 Rb2 34.b6 h5 Trying to make a second weakness 35.gxh5 gxh5 36.Rb8+ Kh7 37.b7 h4 38.Kd1 h3 39.Kc1 Rb3 40.Kd2 h2 White resigns 0-1

January Training (8), 24.01.2006

Craig pulled out the Caro Kann today and got a hard fought victory.
1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 c5 6.0-0 Nc6 [Although I gain tempo with 6...cxd4 7.Nxd4 Bg6 8.f4? cannot be played because of the pins: 8...Bc5 9.c3 Nc6 10.Be3 Qb6 11.b4 Bxd4 12.Bxd4 Nxd4 13.Qxd4 Qxd4+ 14.cxd4 and although White has big pawns, Black's game is safe.]
7.c3 Simply supporting the d4-pawn and seeing where Black will but his knights.
7...Nge7 8.Bg5 This gives me a good target now for my Bishop. The pin is on and Black can't break with f6 yet.
8...Qb6 A good move by Craig, hoping for the exchange of Queens.
9.Qb3 [Fritz likes 9.Na3! Qxb2 10.Nb5! but that is very difficult to see OTB (if you aren't looking for it). I figured that this was the best defense. White's pawns are much better at this point (until Black's reply).]
9...Qxb3 10.axb3 Bxb1 I wasn't sure about this move. I assume the idea is to get his Knight to f5 and to put one of my rooks on an (almost permanently) closed file.
11.Rfxb1 I needed to try to keep some pressure on the half-open a-file.
11...cxd4 12.cxd4 Nf5 Craig has gotten (I believe) what he wanted out of this position: trouble on my d4-pawn, double isolated pawns and one of my rooks doing absolutely nothing.
13.Bb5 Be7 14.Rd1 [Fritz prefers 14.Bxc6+ bxc6 15.Bxe7 Nxe7 16.Ra6 but then that gives Black a huge target on my isolated b-pawns.
16...0-0 17.Rba1 Rab8 18.Rxa7 Nf5 19.g4 Rxb3 20.R1a3 Rxf3 21.Rxf3 Nxd4 An interesting series of moves!]
14...Bxg5 15.Nxg5 h6 16.Nf3 [16.Bxc6+ bxc6 17.Nf3 0-0 18.Ra6 (almost) transposes to the game.]
16...0-0 [Fritz prefers the complications after 16...Kd7 17.Bxc6+ Kxc6 18.Rdc1+ Kd7 than taking the half-open b-file for some unknown reason.]
17.Bxc6 bxc6 18.g4! I thought this was a good aggressive move at the time.
18...Ne7 19.Rdc1 [The idea of 19.Ra4 Rfb8 20.b4 didn't even cross my mind, but now it makes perfect sense! Turn my weakness into a strength!]
19...Rfc8 20.Ne1 I hoped to get f4 in, and then not worry about him chipping away at my pawns, but
20...Ng6 is a good answer for that.
21.Ra6 [A few moves too late. 21.Nd3 allows f4 and the securement of my position by preventing the .. c5 push.]
21...c5! Good move by Craig! He strikes at the proper time.
22.Nd3 [22.Rxc5 Rxc5 23.dxc5 Nxe5 24.h3 Rb8 and although Fritz considers 25.f4 Ng6 26.Ng2 Rxb3 27.Rxa7 Rxb2 28.c6 playable, White is going to have to take real care of the c6-pawn to get any counterplay.]
22...cxd4 23.Rxc8+ Rxc8 24.Rxa7? I though "no prob", I am doing fine, until
24...Rc2! 25.f4 Rd2! 26.f5 Rxd3 27.fxg6 fxg6 and the game is over.
28.Rb7 Re3 29.b4 d3 30.Kf2 Re2+ 31.Kf1 Rxb2 32.b5 Rxh2 33.Ke1 Rb2 34.b6 h5 35.gxh5 gxh5 36.Rb8+ Kh7 37.b7 h4 38.Kd1 h3 39.Kc1 Rb3 40.Kd2 h2 A well played game by Craig. Good pressure and he timed his .. c5 break well and took advantage. 0-1
