 Hmmmmmm, i'm not sure. After 15.Ng5 e6 it's not so clear that white wins,
although it has a clear advantage. One of the problems is that there is not
concrete path for white that wins. I found that the best line with 15.Ng5 leads
to R versus B+P with white having the Rook (+1,40 evaluation of Shredder 8).
While with 15.d5 there is a clear PIECE advantage for white OR a position: BN
versus R with white having BN and with a better positional distribution of
pieces(+2,30 evaluation of Shredder 8).
Can you give your best line for white after 15.Ng5 e6      ?
