This is good enugh if the to-square is always given (as in SAN), so that moves with different to-square would always be rejected anyway. But to determine if a piece has only a single move we disambiguate with unknown to-square. So all moves but the first of a piece would be ignored, making it always pass the only-move test. We now test both from- and to-square, and only ignore moves that have both of these equal to that of an already matching move. --- diff --git a/moves.c b/moves.c index c8f8039..abf1936 100644 --- a/moves.c +++ b/moves.c @@ -2058,7 +2058,7 @@ DisambiguateCallback (Board board, int flags, ChessMove kind, int rf, int ff, in (cl->rtIn == -1 || cl->rtIn == rt || wildCard) && (cl->ftIn == -1 || cl->ftIn == ft || wildCard)) { - if(cl->count && rf == cl->rf && ff == cl->ff) return; // duplicate move + if(cl->count && rf == cl->rf && ff == cl->ff && rt == cl->rt && ft == cl->ft) return; // duplicate move if(cl->count == 1 && kifu & 0x7E && cl->rfIn == -1 && cl->ffIn == -1) { // traditional Shogi disambiguation required int this = 1, other = 1;
