Hello All! It's very important thing to discuss. The strength of engine playing in rook endings is very important. I think that the fine evaluation of rook endings must be based on special knowledge. For example Tarrasch theorem and also special evaluation for pawn structure. There are many things in rook endings which is not common for other stages of the game. For example: rook on open files evaluation. I think that the score of the rook on the open file in rook ending must be based on number of open files and, may be, on other pawn structure parametres. Also the important thing may be is the king placement with relation to enemy/own pawns. For example the pawn which is out of enemy king quadrant is a big advantage in most cases (Because the rook is stronger than king in most cases and to stop this pawn we must use the rook. But this is way to immobilizing the strong piece). In many cases one pawn in rook endings isn't a big advantage, especially for one-sided endings. But it's not easy to found: when the pawn is good and when it's bad (for example Junior7 in many cases decides that the one pawn in rook endings is a near the draw but i think that it's a case of voluntarism :) Have your any non-secret ideas? :) Sincerelly yours, Sergei
