The position is drawn. Yes, but there is something that people keep forgetting about this position. The move 5. Nxc7 may not ever be played in a game, even a fast game. When people claim here that computers or GMs do not see what is going on, they forget that just picking the move Bg2 is basically sufficient. It does not matter if the computer or the GM misses the continuation to allow white to win as long as they pick the continuation to get to that point: 1.Bg2 Qxf4 2.Bxb6+ Kb8 3.Bc7+ Qxc7 4.Na6+ Kc8. At this point in the game, the computer or GM can find the continuation: 5.Bh3+ Kb7 6.Nxc7 Kxc7 7.Kc3 Kd6, etc., regardless of whether they found that continuation at the root position. The point of this position is that it is a draw UNLESS white finds a continuation that wins. The fact that a computer finds 1.Bg2 Qxf4 2.Bxb6+ Kb8 3.Bc7+ Qxc7 4.Na6+ Kc8 5.Nxc7 Kxc7 does not mean that once it gets to move 5 in the game, that it will play Nxc7. Chances are at that point in the game, the computer (or a GM) will almost automatically default to Bh3+. KarinsDad :)
