GM clobbers e4stat

I went to a rapid tournament (G/15 +2) at the St. Louis Chess Club on Saturday. In the second round, I faced GM Alejandro Ramirez. Here's how you beat a 2000 player and make it look easy:

1.c4 c5 2.g3 e6 3.Bg2 Nf6 4.Nf3 Nc6 5.b3 This move order managed to confuse me. After 5.Nc3, I play 5...Qb6 to block d2-d4. But that makes less sense with a b2-bishop to prepare the pawn break. So I played flexibly, developing my bishop and castling and hoping he would commit his knight. Be7 6.Bb2 0-0 7.0-0 Qc7 The queen doesn't belong on this square 8.Nc3 a6 9.Rc1 Qb6 After d4 ...cxd4, the c-file opens up and White has Nd5 tactics, so I move out of the potential pin 10.e3 White wants to recapture on d4 with a pawn. Then the threat of a d4-d5! pawn break causes Black headaches Rd8 11.Qe2 d5 12.cxd5 exd5 13.Na4 Qa7 14.Bxf6 gxf6 I thought that my weakened kingside wouldn't be much of an issue. That turned out to be wrong! 15.d4 cxd4 16.Nxd4 Nxd4 17.exd4 Be6 18.Nc5 Bxc5 19.dxc5 Rac8 20.Qe3 A strong move. White covers c5 and eyes the vulnerable Black kingside d4 21.Qh6 Rxc5 22.Qxf6 Rd7 I thought that the exchange of the passed c5-pawn for my doubled f-pawn favored me. The next move ends any such illusions. 23.Be4 d3 24.Qh6 d2 With the clock ticking down, I had a crazy idea: once he plays Bxh7+, there are no good discoveries! 25.Bxh7+ Kh8 26.Rcd1 Qb8 I was down to seconds and committed a horrible blunder, but Black is already busted 27.Bg6+ Kg8 28.Bh7+ Kh8 29.Bb1+ Kg8 30.Qh7+ Kf8 31.Qh8+ Ke7 32.Qxb8 Bg4 33.Rxd2 Rxd2 34.Qf4 Rd1 35.Qxg4 Rxf1+ 36.Kxf1 Rc1+ 37.Kg2 Rxb1 He held out his hand. I was unsure why - obviously he isn't resigning! Then I noticed that my flag had fallen 1–0

In the next round, I punished a 1500 for playing too solidly in the Sveshnikov. It's absolutely necessary for Black to be energetic and create counterplay.

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6 10.Nd5 Bg7 11.Bd3 0-0 11...Ne7 is the book move. Black must contest the d5-square 12.0-0 Be6 13.Qh5 I like this move. Now Black can't take the d5-knight without dropping a piece. Ne7 14.c4 b4 Now White has complete control 15.Nc2 There's no need to get entangled in 15.Nxb4 Rb8 and ...Rxb2 a5 16.Rae1 Rb8 Black can't create counterplay with ...f5. Also, he can't eliminate the monster on d5 since that would open up the b1-h7 diagonal 17.Nce3 This gets in the way of the rook lift I prepared earlier, but it does prevent Black from starting any counterplay with ...b4-b3. I avoided 17.b3 since then Black could potentially open up the queenside with ...a5-a4. After 17.Nce3, the queenside remains closed and there is very little that Black can do about White's grip on the rest of the board. Ng6 18.Nf5 Bxd5 A blunder in a difficult position 19.exd5 Nf4 20.Qg4 Ng6 21.h4 Winning material Kh8 22.h5 Rg8 23.hxg6 fxg6 24.Nxg7 Rxg7 25.Qe2 25.f4 allows ...Qb6+, which could be annoying. So first I drop back, intending to meet ...Qb6+ ideas with Qe3 or Qf2 f5 26.f4 e4 27.Bc2 I don't remember the rest of the moves, but White eventually won 1–0
