Case contract

Input [board, dead_points, prisoners_held_by_black, prisoners_held_by_white, komi_tenths]. Each listed dead stone is removed once and becomes a prisoner of its opponent (duplicates and empty points are ignored). Territory = empty regions (after removal) bordered by one colour only. Return [terr_b, terr_w, pris_b, pris_w, result] with result "B+x.y", "W+x.y" or "Jigo".

Why this case matters
