and the sacrifice is.... where?

Sorry about the wiev. this is my first try. But I think I've found the correct way to display and should be seen in about 5 minutes..

I put it into a game format so it is easier to see.

can you believe that that bishop was there for 11 moves before it was used again? good game.
