Hello HGM,
I accidenlty stumbled yesterday on the line sorting bug again,while debugging something in Dirty.
The bug happens on sorting matescores only.
I guess the cause is the (10000+moves_to_mate) convention,
which gives longer matelines a higher score,but i did not check the source.

Code: Select all

6r1/1p2kp2/p1b4p/n3p3/2P2p2/8/3r2P1/5BK1 w - - 4 33

Yegh. Indeed I would have to use the reverse comparison for mate scores there.
