Commit ID 10429dd616b97250107a64c1b91fdffee03e4790

Increase see prune depth This seems good at short TC controls. After 10000 games at 20+0.05 ELO: 9.56 +-6.8 (95%) LOS: 100.0% Total: 10000 W: 1949 L: 1674 D: 6377 Testing at long TC and regression testing is still ongoing. So this is a bit speculative commit and could be reverted in the future. Also re-testing at long TC the SEE pruning in PV nodes seems less effective (perhaps even a regression, but still ongoing) so disabled for now. bench: 4968764
