Grischuk-Nakamura, Tal Memorial 2010
(finished just a few minutes ago)
Black to play and win
There are two reasonable ways to threaten mate on g3: 84....Qe1 and 84...Qf3. Both moves have problems: after 84...Qe1, White can try to set up a stalemate defense by allowing ...Qxg3 and running the king to h1. After 84...Qf3, 85.Nxe5+ seems to force a draw: or does it?
Which move would you choose?
