BP Donnelly v P Kroom 1971
Solution
This one took me a while, but when I saw it, it gave me a smile of satisfaction.
Firstly, 1…Bd8?? loses nicely to 2 Qf8+ Kg5 [] 3 Ne4+ Kh4[] 4 g3 mate. Pretty.
My attempt at the solution started with thinking that black needed to make luft for his king: so 1…Qh2+??, which I couldn't make work, so it had to be something else, and moving the Bg5 didn't help, even to e7, which prevents Qf8+. So, examine all biffs and 1…Rf3! comes to mind, and, once seen, is 'obvious'. White can't take the rook (e.g. 2 gf Bf3+ 3 Kg1 Qg4+ etc) and so must move his queen, after which the Rd8 can be taken.
Very nice.
