Short vs Timman, Tilburg 1991

[acase]

This seems to be a tricky one for engines.
The best move is 31.Kh2 with the idea of marching the king on up the dark squares g3, f4, and g5.

[yanquis1972]

what a find, though as albert silver has suggested could everyone please preface these with "test position" for search purposes?

it might be too difficult or require hours of search as far as i can gather. even after Kh2 is made many engines take quite some time to come up with the correct plan for white.
