Finally, trading the bishops off would also make the e5-pawn weak. } 24. Qh3 Bxd4 25. Rxd4 Re8 26. fxe6 fxe6 27. Bg4 { [#] 27.Bg4 takes advantage of the pin on the h-file to attack my e6 pawn. I saw two ways to defend: 1) 27...Rh6 - which I did not like, as white could play 28.Qe3 hitting the rook and centralizing the queen. 2) 27...Qc5 to gain a tempo on White's rook, then moving back to e7 to defend the pawn, protect the h7-rook, and possibly create a threat of ...h5xg4. } 27...

I was not worried about this move. } 33. Qh2 Reg8 { I wanted to go ...Qg5-g3 to trade the queens, then move my rook back to g5 to pressure the e5-pawn. } 34.
