An extreme EAS game by Stockfish against Crafty

[Peter Berger]

This one struck me as borderline insane. I won't claim to be able to say anything meaningful about it, please enjoy.

A 19th Nervous Breakdown game.

[AdminX]

Fantastic game Peter.

[nmcrazyim5]

Apparently 44.Ke5 avoiding repetition was the decisive mistake (44.Kc6 should have been a draw). Crafty played exceptionally well until that point, all things considered. Great game!

I'll give another (IMHO pretty amazing) game where it is easier to grasp the decisive point in the game (It definitely is 70. Rxf3??) . It is even closer to a draw. This one doesn't have fireworks.

To the previous game: there was a method to Stockfish's madness. It played all the relevant moves ( like the early ..Bf5) with 0.00 eval. I have analyzed the opening line some - Stockfish really likes it as a way to equalize in general, and it does.

It outsearches Crafty like mad. Although it doesn't seem to have the intention to create anything and all the 0.00s look the same to it, in every move Crafty has a slight chance to fail. Until it actually happens eventually.

In addition there is zugzwang Crafty doesn't get. Crafty played 90. Kh3 with eval -0.22 and 97. Bg2 with -0.18 ... - Stockfish has since become amazing in understanding it.

This game looks even more amazing to me, as I would have been able to draw it myself at some point ..
