Slater, I let CM9K run for over an hour on my 3.0G P4 HT machine with a custom personality (SS=16) and no Mate in 11 was found. Then forced the line you have for a Mate in 11 (see below) with a strange result. Normally CM9K will find a mate and then improve on it to fewer moves if a solution is possible. It just not do it in this case for some strange reason.

It sees the mate in 11 line with 49.Kb3 in less than a second then returns to the longer mate (mate in 7 at this point) and stays with it.
