Adjust usage of LMR for 2nd move in move ordering Current master prohibits usage of LMR for 2nd move at rootNode. This patch also disables LMR for 2nd move not only at rootNode but also at first PvNode that is a reply to rootNode. passed STC: https://tests.stockfishchess.org/tests/view/620e8c9026f5b17ec885143a LLR: 2.94 (-2.94,2.94) <0.00,2.50> Total: 54096 W: 14305 L: 13996 D: 25795 Ptnml(0-2): 209, 6075, 14192, 6342, 230 passed LTC: https://tests.stockfishchess.org/tests/view/620eb327b1792e8985f81fb8 LLR: 2.94 (-2.94,2.94) <0.50,3.00> Total: 110864 W: 29602 L: 29156 D: 52106 Ptnml(0-2): 112, 11147, 32455, 11619, 99 closes https://github.com/official-stockfish/Stockfish/pull/3940 bench 6820724
