Bxg7 Kxg7/ Ne5 Rfd8/Qg4+ Kf8/Qf5! f6/ Nd7+ Rxd7/ Rxd7 Material is balanced but the knight is out of the game for a couple of moves and the unsafety of the King should count for +1.00 at least. Q+R+R against a naked king is bad... Black has a lot of problems and suffer terribly through light squares. Regards, Miguel
