So, You're Saying: with the forced line 64. Be7 Ne7; 65.Be5 Ne7; 66. Bxc4 Kg7;
and finally with this position after 66..

Two bishops against knight is a draw unless the side with knight makes a mistake, I think.

That used to be the theory until computers solved 5-piece endings. Now we know it's a tablebase win in 66 moves or less, except for the few positions in which black can capture the bishop right away.

Of course, reaching the win against a perfect defense is probably too hard even for some grandmasters. But facing a perfect defense seems to be equally unlikely.

This game is a nice example of the trouble the defending side may face. Black is a veteran Brazilian IM.

Okay, he missed a chance on move 108 to shorten the match. On second look, that would be stalemate.

Suspect it is won, but over 50 moves required. A GM friend of mine beat an IM over the board from a very similar position mind, which was quite an effort I thought!
