Reintroduce doEvenDeeperSearch This patch is basically the same as a reverted patch but now has some guarding against search being stuck - the same way as we do with double extensions. This should help with search explosions - albeit slowly but they eventually should be resolved. passed STC: https://tests.stockfishchess.org/tests/view/639733d0b4e52c95053f3485 LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 514048 W: 136423 L: 135435 D: 242190 Ptnml(0-2): 1425, 56945, 139420, 57685, 1549 passed LTC: https://tests.stockfishchess.org/tests/view/639ab79b93ed41c57eded5c3 LLR: 2.95 (-2.94,2.94) <0.50,2.50> Total: 113800 W: 30642 L: 30190 D: 52968 Ptnml(0-2): 53, 11092, 34178, 11504, 73 closes https://github.com/official-stockfish/Stockfish/pull/4287 bench 3611278
