I haven't tuned into the live broadcast, but looking at the position after Kramnik's 52nd,
I think Shakh wouldn't accept a draw offer anymore - he's gonna have 3 connected passers.
Edit: my bad, I didn't notice the threat of a perpetual or even a mating net (Rg8-g7-g8)
Nd6+ looks like the best move in this light.
