Finally, someone cracked this tough little nut. heinzkat has solved this.

Whoa. I never even looked at this one until now. Wasn't your last one also called Maddening Little Problem [3]?

EDIT: Oh, wait. I confused this with A More Crowded Helpmate.

'Maddening' is a good description for this problem, having never tried a help-mate before this one has got me stumped at the minute. The black queen is killing all of my efforts so far.
