Give bonus for rooks that are alligned with enemy kingring The idea of this patch is that if rooks are not directly attacking the opponent king, they can support king attacks staying behind pawns or minor pieces and be really deadly if position slightly opens up at enemy king ring ranks. Loosely based on some stockfish games where it underestimated attacks on it king when enemy has one or two rooks supporting pawn pushes towards it king. passed STC LLR: 2.93 (-2.94,2.94) {-0.50,1.50} Total: 53672 W: 10535 L: 10265 D: 32872 Ptnml(0-2): 952, 6210, 12258, 6448, 968 passed LTC LLR: 2.94 (-2.94,2.94) {0.25,1.75} Total: 62424 W: 8094 L: 7748 D: 46582 Ptnml(0-2): 426, 5734, 18565, 6042, 445 closes Bench: 4663220
