Interesting to know how much time it needs to find g4 after Nxb2? I think that after Nxb2 it should find g4 with a +2 score if you give it enough time. Movei after Nxb2 can fail high on g4 in 2 minutes on p800(16 mbytes hash was used). After 4 minutes it can solve the fail high with 2.20 pawns score for white. I did not save the analysis and the times are only an estimate based on looking at movei's analysis. Uri
