Mar-03-11  TheTamale: Man, these computers are DEEP.
Sep-27-12  Abdel Irada: Crafty definitely wasn't particularly crafty in this game; in fact, it made numerous unforced errors, as when it pushed e5-e4 on move 21, allowing the white knight to escape to a safe square on d4 with check rather than exchanging with ...♔xb5, or when it took the g-pawn rather than develop its bishop, allowing White to win a rook for its g-pawn.

That said, it is still striking how utterly helpless Black is in the final position:

•The rook on b5 is immune because if Black takes it, his knight is forever sealed out of the queenside, and the white b-pawn will march unimpeded.

•White currently threatens to win the knight with ♖f5†, which can only be met by retreating the knight.

•After, say, ...♘d7, White nearly mates with ♖f5† anyway, and Black has to move his king to g4, allowing a discovered check that picks up the knight.

All told, I'd agree with <TheTamale>: One, at least, of these computers played with astounding tactical depth.
