(1) Margvelashvili - Getz [B38]
Southwest Open, 02.09.2013
[Margvelashvili, George]

1.Nf3 Nf6 2.c4 c5 3.Nc3 g6 4.d4 cxd4 5.Nxd4 Bg7 6.e4 d6 Getz chose the Maroczy system. Solid, but a little bit too passive for my liking. 7.Be2 0-0 8.0-0 Nc6 9.Be3 Bd7?! This is a serious inaccuracy. Black should have exchanged the knights on d4 first. 10.Nc2! Rule of thumb: When you have a space advantage, try to keep as many pieces on the board as possible. Now black struggles to find a decent plan. 10...Rc8 11.f3 Ne8 12.Qd2 Nc7 13.Rad1 Threatening c5. 13...b6 14.f4 Nb8!? Defending against e5 and trying to regroup pieces. 15.b3 Bc6 16.Bg4! f5?! This creates too many weaknesses, better was 16...Bd7 17.exf5 gxf5 18.Bf3 Qd7 19.Nd5! Ne6 20.Rfe1 Strategically black's position is lost, but to his credit, Alec finds the only moves to keep the game alive. 20...Kh8 21.Ncb4 Bxd5 [21...Bb7 22.Bf2+- ] 22.Bxd5 Nc5 23.Bf2?! [23.Bd4 was a lot stronger, with a dominant position.] 23...e5! 24.fxe5 dxe5 25.Qe2 Qe7 26.Nd3 Nbd7?! Allows the following maneuver. [26...Nxd3! 27.Rxd3 Nc6 28.Qh5 Black's position is bad, but still defensible.] 27.Nf4 Bh6? In time trouble Alec makes the decisive mistake. [27...Nf6! was the only move, with the idea 28.Qxe5? (28.Bh4 is stronger) 28...Qxe5 29.Rxe5 Nh5! ] 28.Nh5 Now it's over. 28...Rfe8 29.b4 Ne6 30.Qd3 e4 31.Qc3+ Ng7 32.Bd4 Ne5 33.Rf1! Black cannot defend the f5 pawn. 33...e3 [33...Nxh5 34.Rxf5+- ] 34.Nxg7 Bxg7 35.Rxf5 e2 36.Re1 Ng6 37.Rxe2 Bxd4+ 38.Qxd4+ Qg7 39.Qxg7+ Kxg7 40.Rf7+ Kh6 41.Rxe8 Rxe8 42.Rxa7 Nf4 43.h3 Re2 44.Kh2 Rb2 45.a3 1-0
