Engines won't solve retrograde puzzles for you. They require a very logical mind, something I sadly do not possess.
Originally posted by XanthosNZThe g5 pawn could also be the original g pawn and the g6 pawn could be the h pawn. I agree though, the last move had to be fxg3+ (which is what I assumend you meant). As for what piece or pawn it captured, I have no clue.
Well let's have a stab at this.
The last move must have been black as white is in check. It must have been a pawn capture on f3. So the question is did it come from e4 or h4.
As the d, e and f pawns have not moved the g5 must be the h pawn as it cannot have reached there by any other means. That makes the f3 pawn the c pawn. Therefore it must have b ...[text shortened]... ht squared bishop is actually the promoted a pawn perhaps this is involved in what I'm missing.
Originally posted by SuzianneIt's not a red herring at all, it lets you work out how many captures Black's a-pawn has made, and also it shows that White didn't take any of Black's pawns.
Although now that I think about it, Black's newly promoted light-squared bishop could not have been promoted at b1, since the bishop could not have gotten out... it had to have been promoted at f1, as incredible as that sounds. Still, it looks like a red herring nevertheless.

White is missing 10 bits; Black's a-pawn made 5 captures(then got promoted), the c-pawn 4 captures and the h-pawn 1 capture.
I think we have to name the piece on g3 which got captured...
Originally posted by PeakiteThis is the key to the whole problem. The light-squared white Bishop has nowhere else to die but g6. Therefore, wPg can only die on g3, and the last move is f4xPg3+.
The white squared bishop must have been taken by hxg6 (the a and c pawns must have taken all captures on black squares.
