Something like this is not unlikely to happen in such positions (I think, it is
rather deep, much deeper than a rather early 0,0 might suggest) depending on
HT-size, TBs, etc.

I think 2...Kc6 is enoug for the draw. My current version suggest rather fast f5
(the move also suggested in the analysis at the chessbase page). It also shows a
0.0 score in the root pos.

I think, 2...g6-g5 will lose. BTW. Quark showed the same move move. I believe 2.
f5 or Kc6 will draw.
