Simplification of lazy threshold Passed STC http://tests.stockfishchess.org/tests/view/587846c10ebc5915193f74ec LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 217236 W: 39041 L: 39254 D: 138941 Passed LTC http://tests.stockfishchess.org/tests/view/587e157a0ebc5915193f76e7 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 52396 W: 6883 L: 6804 D: 38709 This submitted version (using if (abs(mg + eg) > 1500) ) seems more logical than the following other green simplification (using if (abs(mg)>1500)) since it can happen than mg_value is > eg_value (about 20% of the time) and the submitted version seems stronger at LTC STC http://tests.stockfishchess.org/tests/view/5879702d0ebc5915193f7585 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 39958 W: 7315 L: 7227 D: 25416 LTC http://tests.stockfishchess.org/tests/view/5879af3e0ebc5915193f7592 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 204322 W: 26529 L: 26648 D: 151145 bench: 6406285
