Remove Overload bonus Compensate by giving the Hanging bonus to weak doubly-attacked non pawn enemies pieces. STC: http://tests.stockfishchess.org/tests/view/5bfd53c40ebc5902bced9237 LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 62107 W: 13664 L: 13622 D: 34821 LTC: http://tests.stockfishchess.org/tests/view/5bfd74700ebc5902bced9618 LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 86406 W: 14381 L: 14365 D: 57660 A possible follow up would be to tune the hanging bonus and/or try to simplify the hanging bonus condition.
