Please forgive me if I'm posting this in the wrong forum--I figure the people posting puzzles would know best.
I want to create a puzzle. But, the prior move must be known, so the solver can be aware that en passant is a possible move. (opponent pawn has just advanced 2 squares). I don't see a way to do this.
Also, the default "mate in 1" puzzle verbiage gives the puzzle away. The idea is, I want a "play your best move" with other options being tantalizing.
Obviously this would be a 'just for fun' puzzle for players in about the 1100-1200 range, but the idea is, white wins with en passant discovered double checkmate.
So. Do I have to be a paying member to get the 2 options I'm looking for, or, is there no way to do it period.
