Raise penalty blocked enemy pawn on 6th rank Idea from Lyudmil Tsvetkov. The value seems to be raised a bit abruptly, but as Gary said, a blocked pawn on the sixth rank has been instrumental in limiting king mobility in multiple losses that I've seen from SF. A blocked pawn on fifth rank is much less serious on the king safety impact. Passed both STC LLR: 2.97 (-2.94,2.94) [-1.50,4.50] Total: 14551 W: 2750 L: 2607 D: 9194 and LTC LLR: 2.96 (-2.94,2.94) [0.00,6.00] Total: 43595 W: 6917 L: 6618 D: 30060 And even a retest at 60" fixed games 40K ELO: 1.79 +-1.9 (95%) LOS: 97.0% Total: 39889 W: 6018 L: 5813 D: 28058 bench: 7154916
