Rh3 gets a small advantage. All other moves lose

Post by Dann Corbit »

[d]r1r2b1k/1bq2p1p/p1npp1p1/2nB2P1/4P1NQ/2p1B1R1/PPP2P1P/2KR4 w - - acd 44; bm Rh3; cce 167; ce 50; pm Rh3 {20} Nf6 {1} Qxh7+ {1}; pv Rh3 h5 Nf6 Bg7 Qg4; white_wins 8; black_wins 2; draws 6;

It seems quite obvious to humans (I guess at least 90% of the audience here would play it.), but I saw some engines take a while to find the best move.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Thanks for the nice test positions. What engines take time to find this? Any top ones?
