Extra thinking before accepting draw PVs. If the PV leads to a draw (3-fold / 50-moves) position and we're ahead of time, think a little longer, possibly finding a better way. As this is most likely effective at higher draw rates, tried speculative LTC after a yellow STC: STC: http://tests.stockfishchess.org/tests/view/59eb173a0ebc590ccbb8975d LLR: -2.95 (-2.94,2.94) [0.00,5.00] Total: 56095 W: 10013 L: 9902 D: 36180 elo = 0.688 +- 1.711 LOS: 78.425% LTC: http://tests.stockfishchess.org/tests/view/59eba1670ebc590ccbb897b4 LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 59579 W: 7577 L: 7273 D: 44729 elo = 1.773 +- 1.391 LOS: 99.381% bench: 5234652
