Adjust singular extension search depth This patch applies a different singular extension search logic in case the position is ttPv && !PvNode. It changes the depth of this search, higher for this types of nodes, and lower for other nodes. passed STC http://tests.stockfishchess.org/tests/view/5e72bbaae42a5c3b3ca2e75e LLR: 2.94 (-2.94,2.94) {-0.50,1.50} Total: 12692 W: 2608 L: 2389 D: 7695 Ptnml(0-2): 238, 1414, 2839, 1601, 254 passed LTC http://tests.stockfishchess.org/tests/view/5e731c07e42a5c3b3ca2e770 LLR: 2.96 (-2.94,2.94) {0.25,1.75} Total: 145716 W: 19218 L: 18626 D: 107872 Ptnml(0-2): 1100, 13605, 42899, 14111, 1143 closes https://github.com/official-stockfish/Stockfish/pull/2590 Bench: 5398277
