Comments.Text: Yes, I can't count. Jon (answer below) is correct - there is a forced mate in 6 but Jon I believe hasn't enough reputation to merely comment rather than answer. He's from the same club as I so he's told me the solution - I'll leave it before I post to see if others can find it, it's quite fun, and Jon's hint is quite good.
