Simplify verification search (#1362) 1. avoid recursive call of verification. For the interested side to move recursion makes no sense. For the other side it could make sense in case of mutual zugzwang, but I was not able to figure out any concrete problematic position. Allows the removal of 2 local variables. 2. avoid further reduction by removing R += ONE_PLY; Benchmark with zugzwang-suite (see #1338), max 45 secs per position: Patch solves 33 out of 37 Master solves 31 out of 37 STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 76188 W: 13866 L: 13840 D: 48482 http://tests.stockfishchess.org/tests/view/5a5612ed0ebc590297da516c LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 40479 W: 5247 L: 5152 D: 30080 http://tests.stockfishchess.org/tests/view/5a56f7d30ebc590299e4550e bench: 5340015
