Round 3 Board 2

1.d4 Nf6 2.c4 d6 3.Nf3
I'm not sure why I played this instead of 3.Nc3 which with one other exception has always been my choice in this position. 3...g6 now he gets a Kings Indian, but has avoided the 4 Pawns Attack. 4.Nc3 Bg7 5.e4 0-0 6.Be2 Na6 at least I had considerable experience with this move from the Black side. However, during the game I couldn't recall the details of any of the critical variations. 7.0-0 e5 8.Be3 Ng4 9.Bg5 Qe8 10.dxe5 dxe5 11.h3 h6 12.Bd2 Nf6 13.Be3 the most popular move, but after 13.Qc1 I lost games to Oleg Zaikov in the 2007 US Chess League and to IM Justin Sarkar at the 2012 Kentucky Open 13...Qe7 14.a3 c6 much better than 14...Nc5 which I played against IM Jonathan Schroer in the 2007 Emory/Castle Grand Prix. 15.b4 Nh5 16.Re1 16.c5 is White's other main line. 16...Rd8 16...Nf4 is much more common 17.Qc2 Nc7 18.Rad1 Ne6 19.Rxd8+ Qxd8 20.Rd1 Qc7 21.Bf1 Bf8 22.g3 Kh7 23.Kh2 Nf6 24.Bd3 Bg7 25.Be2 Bd7 26.c5 Rd8 27.Bc4 Ne8 28.Ne2 Bc8 29.Rxd8 Qxd8 30.Qd3 Qe7 31.Kg2 Bf6

32.Qd2?! with d4 under good control, White should avoid the exchange of knights and finally start sending the f3 knight towards d6 with 32.Nd2 Ng5 33.h4 Ne6 34.Bb3 and White still has some pull. 32...Ng5 hitting e4 and h3, White is forced to exchange and the game is equal. 33.Nxg5+ Bxg5 34.Nc3 Bxe3 35.Qxe3 Kg7 36.Qd3 Nc7 37.Nd1 Ne6 38.Bxe6 Qxe6 39.g4 Qf6 40.Ne3 h5 41.f3

I stopped recording here as he went below 5 minutes in the sudden death time control (I had about 9 minutes). I've attempted to reconstruct the remaining moves. We had a fairly extensive post mortem of the bishop versus knight ending, and didn't find anything for Black, but we didnt' look at any positions resultig from ...exf4 41...Qf4 42.Qc3 Kf6 43.Nf1 Be6 44.Qe3 Kg5 45.Qxf4+? 45.Qd2 is still equal 45...Kxf4? 45...exf4! 46.e5 otherwise it looks like Black can just walk in with Kf6-e5-d4 since (46.Kf2 Kf6 47.Ke2 Bc4+) 46...hxg4 47.hxg4 f6 and I don't see a defense for White 46.Kf2 h4 47.Ne3 Bb3 48.Ng2+ Kg5 49.Ne3 Ba2 50.Ng2 Bc4 51.Ke1 Bb5 52.Kf2 Bc4 53.Ke1 Be6 54.Kf2 f5 55.exf5 gxf5 56.Ne3 f4 57.Nf1 Bc4 58.Nd2 Bd3 59.Ne4+ Bxe4 60.fxe4 Kf6 61.Ke2 Ke6 1/2-1/2
