I am looking for this kind of positions, the idea is to detect that 1.Kxf2 leads
to a draw much earlier because of 1..Qb3

ProDeo's perpetual check algorithm moves to 1.Kg2 after 6 seconds, in normal
mode it needs 3:30

But of course stalemate detections are welcome too such as this famous one.

[d]r7/8/4p2k/3p1bR1/7r/Np6/1P6/K5R1 w - - bm Rh5+; id The King - Nimzo (1993);

ProDeo's perpetual check algorithm needs 59 secs to find 1.Rh5+

My best,

Ed
