Kxf2 Kg6 (result?) 40/40 and crafty is not a serious analysis. We need a correspondence game to get a better opinion which side is better after g3(I am also not sure about it) I analyzed 16...Qh2 17.f5 h5 with Deep Fritz6 and it got the following analysis (you can see that the queens are traded in the main line) I suspect that 17...h5 is not the best move(inspite of the fact that it was proposed) and black needs to develop pieces.
