It did not ponder correctly based on Junior's logfile(it expected 37...h5 and not 37...axb3) but it is still possible that the hash tables helped it to get bigger depth because it had better order of moves. I also doubt if depth 17 means that it had a score at depth 17. It is possible that it jumped from depth 15 to depth 17 and had not enough time to get a score for the move at depth 17 because of the fact that it was slower. Uri
