hello syzygy, thx for your response
...no, in the pos from above SF shows correctly Kc5 as the only drawing move and shows -153 or so for all other moves ProbeLimit was set on default (7)
the problem is that it stops analysing after about 5 sec without making a move...this is by far not the only pos where SF behaves like this...practically all endgames produce this bug, eg:
8/8/4b1p1/2Bp3p/5P1P/1pK1Pk2/8/8 b - - 0 1
here SF stops thinking after less than 1 sec and plays no move, CPU-usage: 0 %
but if i set ProbeLimit to 5 or 0 eg there will be no issues at all...
so id assume it has sth to do with incomplete TB-sets !??
any idea ?
