Tweak Late Move Reduction at root Maintain best move counter at the root and allow there only moves which has a counter of zero for Late Move Reduction. For compensation only the first three moves are excluded from Late Move Reduction per default instead the first four moves. What we can further do: - here we use a simple counting scheme but perhaps some aging to fade out early iterations could be helpful - use the best move counter also at inner nodes for LMR and/or pruning STC: LLR: 2.95 (-2.94,2.94) [0.50,4.50] Total: 17414 W: 3984 L: 3733 D: 9697 http://tests.stockfishchess.org/tests/view/5d6234bb0ebc5939d09f2aa2 LTC: LLR: 2.96 (-2.94,2.94) [0.00,3.50] Total: 38058 W: 6448 L: 6166 D: 25444 http://tests.stockfishchess.org/tests/view/5d62681a0ebc5939d09f2f27 Closes https://github.com/official-stockfish/Stockfish/pull/2282 Bench: 3568210
