5 years agoGive bonus for rooks that are alligned with enemy kingring
Vizvezdenec [Mon, 25 May 2020 18:14:07 +0000]
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.
