Tweak doubly singular condition (Topo's patch) This patch relax a little bit the condition for doubly singular moves (ie moves that are so forced that we think that they deserve a local double extension of the search). We lower the margin and allow up to six such double extensions in the path between the root and the critical node. Original idea by Siad Daboul (@TopoIogist) in PR #3709 Tested with the previous commit: passed STC: LLR: 2.94 (-2.94,2.94) <-0.50,2.50> Total: 33048 W: 8458 L: 8236 D: 16354 Ptnml(0-2): 120, 3701, 8660, 3923, 120 https://tests.stockfishchess.org/tests/view/614b24347bdc23e77ceb88fe passed LTC: LLR: 2.95 (-2.94,2.94) <0.50,3.50> Total: 54176 W: 13712 L: 13406 D: 27058 Ptnml(0-2): 36, 5653, 15399, 5969, 31 https://tests.stockfishchess.org/tests/view/614b3b727bdc23e77ceb8911 closes https://github.com/official-stockfish/Stockfish/pull/3714 Bench: 5792377
