I've felt obliged to say "can you put some deliberate >mistakes in so I can find _something_?" ;) It has mistakes even in his release versions Give the following position to Genius3 and tells me what is says I found many years ago that it play the wrong move [D]5bkq/r4p2/8/4R3/2pB4/4n2Q/p1p1r3/K5n1 w - - 0 1 Note that the original mistake was in case that Genius say shorter mate than the real mate and I changed the position to concince it to play losing move instead of winning move. It seems that there was bug in Genius and when it searched 1.Rg5+ B(Q)g7 Qxh8+ is considered that check as mate. I guess that its logic was something like Bxh8 is illegal so it means that h8 is protected so it means that Kxh8 is illegal and it is a waste of time to check it. I did not check if other genius version except genius3 have that bug. Uri
