Man am i happy i do not have black in that position. Black must beg for mercy from white to draw this. After i move Nd7-f6 now, which is pretty desperate move, then: 00:19 0 0 1421505 (107762) 11 0.595 Ne7xg8 Ra8xg8 c2-c3 d5xe4 g2-g3 Bb7-d5 h2-h4 Rg8-g6 Qh6-d2 Kh8-g8 Be2-h5 Nf6xh5 Qd2xd5 So score slowly going up again for white. White is playing a royal game here. Black must go back to the chessclub and learn chess, he made some strategic mistakes here if he allows all this!
