13.e5?!

[I considered but rejected 13.Bg5, though in retrospect it looks like a good move. 13.Ne3 with the idea of Ng4 also looks strong]

13...dxe5 14.dxe5 e6 15.Bb5?!

[15.Bf4!? Bb7 16.Rd6 looks best for white]

[20.b3!?= Fritz]

20...Nxe5 21.Bxg7 Nxf3+ 22.Nxf3 Kxg7 23.Rd4 Bxf3 24.gxf3?

[Mac Intyre called this move "un-masterly". He said my desire to maintain control of the d-file did not justify the destruction of my kingside pawns. The course of the game certainly seems to prove him right]

[59.Ra6 Rxf3 60.Ra5+ Ke6 61.Rxa4 Rxf2 was better, but would not have changed the outcome]
