Extend quiet tt moves at PvNodes Idea is to extend some quiet ttMoves if a lot of things indicate that the transposition table move is going to be a good move: 1) move being a killer - so being the best move in nearby node; 2) reply continuation history is really good. This is basically saying that move is good "in general" in this position, that it is a good reply to the opponent move and that it was the best in this position somewhere in search - so extending it makes a lot of sense. In general in past year we had a lot of extensions of different types, maybe there is something more in it :) passed STC LLR: 2.96 (-2.94,2.94) <-0.50,2.50> Total: 42944 W: 10932 L: 10695 D: 21317 Ptnml(0-2): 141, 4869, 11210, 5116, 136 https://tests.stockfishchess.org/tests/view/614cca8e7bdc23e77ceb89f0 passed LTC LLR: 2.93 (-2.94,2.94) <0.50,3.50> Total: 156848 W: 39473 L: 38893 D: 78482 Ptnml(0-2): 125, 16327, 44913, 16961, 98 https://tests.stockfishchess.org/tests/view/614cf93d7bdc23e77ceb8a13 closes https://github.com/official-stockfish/Stockfish/pull/3719 Bench: 5714575
