Breunor: < An Englishman> As for the game itself, it seems unlikely that we'll ever see 5.Ne2 again. I checked the Opening explore, it is indeed the only game n the database with 5 Ne2.
A fast evaluation is:
1) -0.23 (23 ply) 5...c5 6.c3 Nc6 7.Nf3 Be7 8.g3 O-O 9.Bg2 b6 10.O-O Ba6 11.h4 Rc8 12.Re1 h6 13.Bf4 g5 14.Bc1 Kg7 15.hxg5 hxg5 16.Qd2 Rh8 17.Nxg5 Ncxe5 18.dxe5
f3 on move 25 or 26:
On move 25 we get f3 is second best, but better than the game move Ne5:
1) -0.06 (25 ply) 25.Qd2 Qxd4 26.Qe3 Qf6 27.f3 Bxf4 28.Nxf4 Qxf4 29.Qxf4 Rxf4 30.Rab1 Kf7 31.Rb3 Ke7 32.Kf2 e5 33.Re1 Kd6 34.Rbe3 Rxb4 35.Rxe5 h6 36.Re7 Rb2+ 37.Kg3 Rxa2 38.Rxg7 Bf5 39.Ree7 d4 40.Rxa7
2) -0.71 (25 ply) 25.f3 Qxd4+ 26.Kh1 a5 27.a3 Ra8 28.Rg1 g6 29.Nc5 Qxf4 30.Qe2 Bc8 31.Rac1 Qf7 32.Nd3 Ba6 33.Rxc6 Qd7 34.Rxa6 Rxa6 35.Nc5 Bxc5 36.Qxa6 Bxg1 37.Kxg1 axb4 38.axb4 Kh8 39.Qe2 d4
On move 26, Qe1 in he actual game is losing move:
1) -7.08 (25 ply) 26...Rg4+ 27.Nxg4 Qxg4+ 28.Kh1 Qf4 29.Kg2 Qxh2+ 30.Kf3 Qf4+ 31.Ke2 Qe4+ 32.Kd1 Qxd4+ 33.Ke2 Bc8 34.Rb1 Ba6+ 35.b5 cxb5 36.Kf3 Qf4+ 37.Ke2 b4+ 38.Kd1 Qd4+ 39.Qd2 Qg4+ 40.f3 Qf5 41.Rf2 Qxb1+ 42.Qc1 Qd3+ 43.Qd2 Qxd2+ 44.Rxd2 Bc4 45.Rg2 a5 46.Kc1
Once again, f3 is second best, but Re1 keeps white in the game; it looks like the key is that if black takes on h2 the white king can escape to f1. f3 however keeps white behind quite a bit:
1) -0.27 (20 ply) 26.Re1 Qf5 27.Re3 Bxe5 28.dxe5 Rxb4 29.Qd3 Qxd3 30.Rxd3 c5 31.Rb3 a5 32.Rxb4 axb4 33.Kg2 Be8 34.Kf3 Bg6 35.Rc1 c4 36.Ke3 Kf7 37.Kd4 Be4 38.Rg1 g6 39.Kc5 b3 40.axb3 cxb3
2) -2.62 (20 ply) 26.f3 Qe3+ 27.Kh1 Rxd4 28.Ng4 Qf4 29.Qc1 Rxb4 30.Qxf4 Rxf4 31.Rfe1 c5 32.Kg2 Rf5 33.Rab1 h5 34.Ne3 Rg5+ 35.Kh3 Bc6 36.Rg1 Rxg1 37.Rxg1 Kf7 38.Nf1 c4 39.Ng3 d4 40.Nxh5 Bxf3 41.Rxg7+ Kf8
