Adjust pawn span Run as a simplification a) insures that pawn attacks are always included in the pawn span (this "fixes" the case where some outpost or reachable outpost bonus were awarded on squares controlled by enemy pawns). b) compute the full span only if not "backward" or not "blocked". By looking at "blocked" instead of "opposed", we get a nice simpli- fication and the "new" outpost detection is almost identical, except a few borderline cases on rank 4. passed STC http://tests.stockfishchess.org/tests/view/5d9950730ebc5902b6cefb90 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 79113 W: 17168 L: 17159 D: 44786 passed LTC http://tests.stockfishchess.org/tests/view/5d99d14e0ebc5902b6cf0692 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 41286 W: 6819 L: 6731 D: 27736 See https://github.com/official-stockfish/Stockfish/pull/2348 bench: 3812891
