I tried running the position after Nxh6 c3 Nf5 cxb2 Qg4, since both variations
had these moves in common. The analysis was stopped after an hour.

It doesn't get all the moves right, but it discovers the impact of Kh2 twice
(depth 9 and 11). I imagine it'll switch between Bc8 and g6 for a while, which
will take a long time.
