Question about a proof game
Yesterday, Leither123 posted the position rnbq1r2/ppppp3/Rr3Pkn/8/P2BB3/3PP1R1/1bP1QPP1/1N2K1N1
in the Shortest-proof-game challenge of the Fun With Chess forum at chess.com. It has a unique SPG in 15.5 which ends with a double check by an en passant capture. He posed a question as to the shortest such unique SPG.
I wonder if someone here knows of other positions with unique SPGs ending in double check by en passant capture, and what the record is for the shortest such proof game.
Here is a link to Leither123's posting of the position.
