My new engine, to be released in the next couple days (after I finalize it's
name) finds it in a bit over a minute. this makes me quite happy as it looks
like a pretty difficult problem, and a few much better engines i tried it with
didn't find the move in the time i gave them.

(in reality, probably a sign i have the king safety param turned up too high ;-)
