Sorry to disappoint you, but: no, Chest will not slaughter them here, since finding *some* forced mate is a quite different job, than what Chest normally does. To find that there is no mate in 8, Chest on a PIII/550 with 500MB cache already burns over 20 minutes for the first of the three positions, and 48 minutes for the third. I have plans to introduce a sort of mate finder mode (what leonid calls "quick logic"), where the attacker is restricted to only perform checking moves, except for say one quiet move. Such a job will be much quicker, of course. In *that* mode, Chest probably slaughters them, but that remains to be seen.
