Up Topic The Rybka Lounge / Computer Chess / TCEC game 60: most brilliant move of the Century?
- - By Venator (Silver) Date 2020-10-10 04:35 Upvotes 2
After a shufflefest the game explodes starting from 143. Bh4! Take a look at 150. Qh5!!!, this must be one of the most brilliant and shocking moves of the Century. A whole queen up black is completely helpless against what follows. Stunning!

I wonder if that was purely an nn find by stockfish. Either way nice work.

LC0 can also find the queen sac, both with a big net and a little net.

I guess that the real brilliance is earlier

After 34. dxe5 {TCEC 0.22} Nd7 {TCEC 0.00} Stockfish had 70 more consecutive 0.00's through the end.
Interesting that both agreed, more or less, that the knight pair was as good as the bishop pair.

Just briefly looking at the free online database Stockfish seems to improved over human games.

Stockfish played the rare 7...Bxf3, I wonder what 7...Bh5 was for in the above.

Sorry about my long Alekhine post here, I should have made a new thread for it.

Here is a queen sacrifice.
Although it is for 2 minors white later sacrifices more to win.
It is flawed though, black should have equalized.
I think the YouTube author at least missed 21...Rc8! =, with the idea of returning 2 exchanges for white's bishop pair (..Rx(B)c3 and allowing Bx(R)e6) to lessen the attack.
