Rf7 +1.49 Also I wanted to mention that i let fritz look at the game from the end of the game up untill Bxg7 and i found that there were better moves which show no advantage for white that Portish missed. But for Kasparov to not play the best move is surprising. Bxg7 is an exclam move but only for shock value.
