Simplify pawnless endgame evaluation Retire KmmKm evaluation function. Instead give a very drawish scale factor when the material advantage is small and not much material remains. Retire NoPawnsSF array. Pawnless endgames without a bishop will now be scored higher. Pawnless endgames with a bishop pair will be scored lower. The effect of this is hopefully small. Consistent results both at short TC (fixed games): ELO: -0.00 +-2.1 (95%) LOS: 50.0% Total: 40000 W: 7405 L: 7405 D: 25190 And long TC (fixed games): ELO: 0.77 +-1.9 (95%) LOS: 78.7% Total: 39690 W: 6179 L: 6091 D: 27420 bench: 7213723
