Refine rook penalty on closed files +-----------------+ | . . . . . . . . | All files are closed. Some files are | . . . . . o o . | more valuable for rooks, because | . . . . o . . o | they might open in the future. | . . . o x . . x | | o . o x . x x . | | x o x . . . . . | x our pawns | . x . . . . . . | o their pawns | . . . . . . . . | ^ rooks are scored higher on these files +-----------------+ ^ ^ Files containing none of our own pawns are open or half-open (otherwise they are closed). Rooks on (half-)open files recieve a bonus for the future potential to act along all ranks. This commit refines the (relative) penalty of rooks on closed files. Files that contain one of our blocked pawns are considered less likely to open in the future; rooks on these files are now penalized stronger. This bonus does not generally correlate with mobility. If the condition is sufficiently refined in the future, it may be beneficial to adjust or override mobility scores in some cases.
