Remove Threat Extension Great code simplification: - instead do not futility prune threat refutations. allows_move() is therefore removed. 4000 games at 50,000 nodes/move: 1085-989-1926 [51.2%] LOS=98.3% 4000 games in 10"+0.1" 756-751-2493 [50.1%] LOS=55.1% EDIT: I have retested the patch of Lucas in a slightly different form (without pruning in PvNode) and test mre or less confirms that 60 lines of code are totally unuseful: After 6195 games at 15"+0.05" 1333 - 1325 - 3537 ELO 0 bench 5140990
