I looked into your position and, by precaution, into your solution. Position could be just too deep for my program. Mine goes only 13 moves deep and no more. In the next version, when it will be no more DOS program, will make it much deeper. Your time for my position is good. I was not able to solve it by brute force since 9 moves took already 4 hours and 39 min. Only 10 move is not sure for me. In 11 mate existe and was solved by selective. Probably somebody will go in it with Heiner solver that is quick in brute force and use hash successfully. Cheers, Leonid. >Angrim
