Unfortunately I did not have Shredder at this point of the game. I have another game when I know that I did not follow shredder's opening book and I believe that I was right. It is the game against GM har aven. 1.g3 d5 2.f4 h5 3.Nf3 h4 4.Nxh4 e5 I believe that 4...e5 is the best move(this move surprised my opponet that gave me a long condition for 4...Rxh4) He thought a long time and played 5.Ng2(I think that I have a good position also after 5.Nf3 exf4) I played a novelty 5...Nf6(I found only 5...Nh6 in my database) and I believe that I have an advantage in the game after 6.e3 Nc6 7.d3 Bg4 8.Be2 Qd7 9.Nd2) Uri
