Amazing, astounding, jaw-dropping game from TCEC

[Guenther]

Hello Jouni:

5 minutes analysis: 26. hxg3? but 26.fxg3! draw. Very difficult to the most engines.

Good catch! I agree with you, it is not as easy as 26.- Qe2??, g2#.

Well, your analysis also shows though that even Qxg3 never leaves a draw score up to the final depth 34.
At least we can agree that hxg3 was a blunder in that game.

There were more than 2,000 TB hits to the full set of 3, 4 and 5-man Syzygy EGTB.

SF thought that 26.- hxg3 was the only move with plus eval up to depth 24. This move was first considered bad at depth 27.
