New Test Position for NN Engines

Post by Dicaste »

[d] 6k1/pp3p1p/1q1b2p1/3Q1P2/3P1P2/8/PPr1r2P/R1BR3K b - - 0 20

Best move is Qb4! (Atleast that's what i found) but most of the engines prefer Qd8 and some few prefers Rxh2+. I think it's a great position for test suites and i like to share.

Another great example of position where any sane move wins.
One could call it one of positions of all time.
