Do more LMR for captures This patch enables LMR for all captures at allNodes that were not in PV. Currently we do LMR for all captures at cutNodes so this is an expansion of this logic: now we do LMR for all captures almost at all non-pv nodes, excluding only allNodes that were in PV. passed STC https://tests.stockfishchess.org/tests/view/5fe50b9d3932f79192d3973c LLR: 2.95 (-2.94,2.94) {-0.25,1.25} Total: 83128 W: 7606 L: 7368 D: 68154 Ptnml(0-2): 292, 5905, 28939, 6129, 299 passed LTC https://tests.stockfishchess.org/tests/view/5fe552e43932f79192d39744 LLR: 2.92 (-2.94,2.94) {0.25,1.25} Total: 13968 W: 568 L: 466 D: 12934 Ptnml(0-2): 5, 418, 6043, 506, 12 closes https://github.com/official-stockfish/Stockfish/pull/3273 Bench: 4194835
