A couple of QSearch busters!

Postby thevinenator » Sun Feb 19, 2017 3:55 pm

found these on talk-chess... you are evil, Dann Corbit!!

B2R4/1nQqQ3/1QrbrQ2/NqqkqqN1/1QqqqQ2/2QbQn2/3B2R1/3K4 w - -
r2k3r/BPb1qbPB/q2qq2q/1Nn2nN1/qQQQQQQq/8/q1RRQ2q/3K4 w - -

my program didn't finish ply 1 after 5 min.

extreme case, for sure, but perhaps there is something wrong with what I allow for QS moves.. time for some debugging

Any bugs found? My engine takes 15 minutes for the first ply which is too long I guess...

if I only consider "good captures" in QS, it goes faster.
