Hi
Black should not have touched the Bishop.
7...e5 start making waves in the centre was far better.
(Infact anything but taking the Bishop was far batter).
Nice game but if I may chip in.
You had a chance to get your Queen to h5 with tempo.
OK it it does not matter here, but in another game it may.
(it's one move longer but you have to see the idea).
1.d4 Nf6 2.Bg5 e6 3.e3 Nc6 4.c3 Be7 5.Bd3 O-O 6.h4 h6
7.Nd2 hxg5 8.hxg5 Nh7 9.Bxh7+ Kh8 10.Bb1+ Kg8 11.Rh8+
Kxh8 12.Qh5+ Kg8 13.Qh7
This tempo gaining ploy is worth knowing and it crops up quite
often, you will use it in future games.
