14 Nd6 wins the bishop and forces the King out
15 Re8 wins materials (Q against R+N or R against N+p)
your 16 Ng5+ is met by Qxg5 but instead there is
16 Ne5+ Kf6 then 17 Qf3 and his bishop is pinned. If his King go to the e column, Nc6+ and he loses his queen.So 17 Re8 and 18 g4 wins the bishop
In this game I recently played, I launched an aggressive attack on the king early. Could you give some tips on how to land a crushing blow in games like this? I'm sure that there are faster wins. Some key positions are after 16...Kg6, 17...h6, 22...g6, and 23...Rxg6, where I am sure I missed more decisive moves.
