Rethink En Passant Evasion Capture It now checks if it were a discovery attack instead of the attacking piece is the double-moved pawn. As a side effect, certain illegal fens have different, and slightly more logical move generation. There is no intend to maintain particular behavior for such non-reachable fens.
