11.g4!?
[11.Nxe4
at first glance simply appears good for White. However, after the minor pieces have been exchanged the Black Queen has a clear potential for counter-play on the dark squares causwd by the weakening move b3. As black also has possibilities of c4 or a5-a4, 11g4 is a good practical choice.]
11...0-0
Castling into the attack but Black's kingside is inherently sound so White should not yet be able to win by direct means. I would be tempted by 11..Nd5 seeking counter-play down the g-file or by ..Nb4 or ..Nf4

13.Nxe4
Bxg5??
Losing. White is not yet threatening anything so Black had no need to panic. 13..a5 waiting for White to declare his intentions would be my choice.
14.Rg1
Bf6?
Equally bad is 14..Bh6 15Qh5, so black should settle for the lost ending after: [14...f6
