Ok, the white play 23.g5!? (this was the 23° move of game).
Then continues: 23. .. Axg5 24.Axg5 Dxg5 25.Cd1 Cc8 26.Tb8 Cd6 up to this point equal to your Rybka analysis.
Now which move play white?
I really don't understand the strategy of the white.
It plays the surprising (at least for me):
27.h4!
I didn't understand. The white self destructive the defense of the King. In exchange for what?
Unlikely chance of attack? but we look as the game continued:
27. .. Dxh4 28.De5 De7 29.Axd5 f6 30.Df4 Cb5 31.Dg3 Rh8 32.Tf2 Cd6 33.c4 f5 34.Cc3 Dc7 35.Tfb2 De7 36.Df4 Ta6 37.Cb5 Axb5 38.Txf8+ Dxf8 39.cxb5 Tb6 40.a4 De7 41.Tc2 Df6 42.Te2 De7 43.Rg2 Tb8 44.Tc2 Tc8 45.b6 h5 46.Tb2 Df6 47.Tb1 Td8 48.Th1 Dg6 49.Rf2 Dh6 50.Dxh6+ gxh6 51.e7 Tb8 52.Tg1 Rh7 53.Tg8 Txg8 54.Axg8+ 1–0
Certainly the black could defend itself better (ex: 29. .. fxe6 is better of f6, for me). I would love to read your analysis on black defense. But there is no doubt that after this double pawns sacrifice, white gets a positional advantage. The maneuver that seemed a not positional sense, had a positional logic.
This game is a nice example of the progress of engines.
Then continues: 23. .. Axg5 24.Axg5 Dxg5 25.Cd1 Cc8 26.Tb8 Cd6 up to this point equal to your Rybka analysis.
