It seemed likely that White was going to enter into the Colle System, an innocuous looking opening that can pack a lot of venom.

A Kings Indian type set-up is normally the best way of dealing with it.

Probably 9...Nd7 is better here but I realised that my Knight could not easily be driven away and f4 looked very inviting.
10.g3?!
Steinitz said never make unnecessary pawn moves in front of your King and 10.g3?! is certainly unnecessary. The White squares around White's King are severely weakened. [Fritz 8: 10.Nb3!

11.Kg2
The tactical antennae of any decent player should now be twitching violently! The geometrical pattern between g2, e2 and f4 should almost literally be flashing amber!
11...Qd7
12.Rh1??
When a player is considering moving a piece that severely cramps his King he should always take a very long look first. 12. Rh1 allows, at the very least, 12...Bh3+ incarcerating both White's King and his Rook on h1. Indeed when I thought that he might play this Bh3+ was the only move I considered; sensibly, though, I now had another look.
12...Nf4+!!
If 13.gxf4 Bh3+ and 14...Qg4# White's Queen is lost. 0-1
