The chessbase interface have different rules then crafty. It does not like positions when max(number of white bishops-2,0)+max(number of white knights-2,0)+max(number of white rooks-2,0)+max(number of white queens-1,0)+number of white pawns>8 It also does not like cases when it is truth for black and does not like positions with more or less than one king for one of the sides It does not like positions when the side to move threats check or positions when there are pawns in the 1st or 8th rank. There is no problem with other positions including this position that is illegal: [D]B1Bk4/1B6/B1B5/3B4/4B3/5B2/6B1/4K2B w - - 0 1 It is interesting to know how much time do your program need to see the draw(if your program does not accept the position then you may remove one bishop from the board). Can chest prove that there is no mate when the number of moves is not important? I have no problem to prove it. Uri
