Extend dangerous passed pawn moves (#2089) Introduce a new search extension when pushing an advanced passed pawn is also suggested by the first killer move. There have been previous tests which have similar ideas, mostly about pawn pushes, but it seems to be overkill to extend too many moves. My idea is to limit the extension to when a move happens to be noteworthy in some other way as well, such as in this case, when it is also a killer move. STC: LLR: 2.96 (-2.94,2.94) [0.50,4.50] Total: 19027 W: 4326 L: 4067 D: 10634 LTC: LLR: 2.94 (-2.94,2.94) [0.00,3.50] Total: 93390 W: 15995 L: 15555 D: 61840 For future tests, it looks like this will interact heavily with passed pawn evaluation. It may be good to try more variants of some of the more promising evaluations tests/tweaks. Bench: 3666092
