nice sac from FIDE Nations Cup

Post by jdart »

Yu-So, FIDE Chesscom Online Nations Cup (11) 2020. Yu played Ng5+! Not too hard for Stockfish but not trivial either.

Minic is blind to this. Wants Qe2 or h5 or Kh2 or even Qa4

SF here is finding Ng5+ but as soon as I activate multiPV, it lost it in favour of Bg5 which is perpetual.

Does not take the Android version to long to find it also. (i5 Google Pixel Slate)

Komodo spots it but does not see that it is winning right away. UPDATE: It took about 6 minutes for Android Komodo to start seeing an advantage for white.

Re: nice sac from FIDE Nations Cup

Post by Vinvin »

Very interesting position. No easy for strong engines.
I set up a set with 6 times this positions, I tested Stockfish_2020_05_02, Black-Diamond-XI, Bluefish-XI, Corchess_V6 and Crystal_2020_05_02.
CPU i7-6*4GHz, under 120 seconds, only Bluefish-XI solved it each time.
Here are the individual results :
