Commit ID beaadd65474c7cf09b13b8cbeeca769e2737f049
Author Joost VandeVondele

Correctly prevent recursive verification in nmp. As discussed with @pb00068, the condition to prevent recursive verification was not completely correct. This patch corrects that condition, and adds an assert. In the current implementation, recursive verification needs to be avoided in order not to break the verification of the move closer to the root (i.e. to not set thisThread->nmp_min_ply to zero prematurely). This patch is tested as a bug fix, based on and tested against PR #1609 . passed STC: http://tests.stockfishchess.org/tests/view/5b050f170ebc5914abc129c5 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 7875 W: 1669 L: 1523 D: 4683 passed LTC: http://tests.stockfishchess.org/tests/view/5b0513970ebc5914abc129cd LLR: 3.00 (-2.94,2.94) [-3.00,1.00] Total: 24048 W: 3525 L: 3407 D: 17116 Bench changes at high depth.
