[D]r3br2/2q2pbk/p2p1npp/nppP4/4PR2/1PP1B1NP/P1BNQ1P1/R5K1 w - - 0 1 Yace could learn a score of +0.42 from 1.Nf5 from the following tree Liberzon said about the move 1.Nf5(typical sacrifice) I wonder if there are a lot of games when humans played a similiar sacrifice and if the sacrifice was also correct in these games. Here is analysis (note that in the game white blundered by 2.e5 but I tried to analyze to see if liberzon was correct when he said that white had a winning position after 2.Rxf5 and it seems that he was correct inspite of not proving a forced win) [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "New game"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "r3br2/2q2pbk/p2p1npp/nppP4/4PR2/1PP1B1NP/P1BNQ1P1/R5K1 w - - 0 1"] [PlyCount "5"] 1.
