Martin Burrows - Brandon Clarke, Leics County Champs 2008[Black to play and win].
The answer is : 27. ... Qc2+ 28. Ka1 Qxd1+!!
Wow! A spectacular move! Now, if 29. Rxd1, then the knight fork Nc2+ regains the queen and mate on c1 follows. Martin, hoping for a blunder by Brandon, played: 29. Nxd1, but Brandon was having none of it: 29. ... Rc1+ and Martin resigned since it is mate next move.
