Furthermore, instead of null moves, it rejected moves on the main diagonal when legality checking was off. Also exclude moves with empty squares and enemy pieces. --- diff --git a/backend.c b/backend.c index 4904638..dd4b0be 100644 --- a/backend.c +++ b/backend.c @@ -4360,7 +4360,8 @@ ParseOneMove(move, moveNum, moveType, fromX, fromY, toX, toY, promoChar) if (appData.testLegality) { return (*moveType != IllegalMove); } else { - return !(fromX == fromY && toX == toY); + return !(*fromX == *toX && *fromY == *toY) && boards[moveNum][*fromY][*fromX] != EmptySquare && + WhiteOnMove(moveNum) == (boards[moveNum][*fromY][*fromX] < BlackPawn); } case WhiteDrop:
