I think better is 1.fxg6
After your 1.Be5 a2 2.fxg6 Black can play 2...Kg8! and have a possibility to win.
Maybe, I can't be friendly, but let me be useful.

If you put [d] in front of the fen then a diagram will be created---and you won't need the image file.

It should have been not only mentioned in the original posting, it's just another puzzle.
Louis and I simply started from a wrong fen without the castling- right
http://www.talkchess.com/forum/viewtopi ... 57&t=57694
We didn't have any from the very start, so it should have been mentioned indeed here
