Introducing new concept, saving principal lines into the transposition table to generate a "critical search tree" which we can reuse later for intelligent pruning/extension decisions. For instance in this patch we just reduce reduction for these lines. But a lot of other ideas are possible. To go further : tune some parameters, how to add or remove lines from the critical search tree, how to use these lines in search choices, etc. STC : LLR: 2.94 (-2.94,2.94) [0.50,4.50] Total: 59761 W: 13321 L: 12863 D: 33577 +2.23 ELO http://tests.stockfishchess.org/tests/view/5c34da5d0ebc596a450c53d3 LTC : LLR: 2.96 (-2.94,2.94) [0.00,3.50] Total: 26826 W: 4439 L: 4191 D: 18196 +2.9 ELO http://tests.stockfishchess.org/tests/view/5c35ceb00ebc596a450c65b2 Special thanks to Miguel Lahoz for his help in transposition table in/out.
