More importantly, none of the engines in my PC (Houdini, Rybka, Stockfish etc.) could find the winning move 16.Bd6!! in 22-23 ply depth. The best they could find was 16.Nf4. This revealed how they still lacking in finding winning combination where a series of moves, even tactical, is necessary. Would the programmers get their hands on this game and find a way out?
