I've really got to think things through before string posting in case I look like an idiot...
the pawn is on f5. And here's why.
So, the bishops on f8 and c1 can just get captured by knights, I don't really see why they aren't there but I'm not sure this impacts the solution.
The black knight has to get sacrificed on g3 as it is the only way to get a pawn there which means black's light squared bishop needs to get sacked on either f3 or f5 to get a pawn to the f file.
How do you do this though? You need to get the light squared bishop out but the only way this is possible in the diagram is for white to play Bc6 at some moment. The white knight can't do this because that has to be taken on b6. For this, you obviously need to move the white light squared bishop and, ta da, this means you have to move your e-pawn making exf3 impossible. Hence, the bishop must have been taken on f5.
Phew, 3rd time lucky
