CBM Blog: Coordination is crucial + the king attacks

by ChessBase
8/23/2011 – When two rook fight against a queen it is often extremely important whether the rooks can coordinate or not. That is the first lesson of our endgame expert Dr. Karsten Müller, who goes on to show us how normally drawish opposite colored bishop endings can be transformed if there are rooks present. Today's lessons include a very instructive blitz game. Look and learn.

The king attacks

Pure opposite colored bishop ending have a large drawish tendency, but matters are completely different if both sides have an additional rook. Here the guideline from the middlegame, that opposite colored bishops favor the attacker, gains in importance. Usually blitz games should not be analysed, but I found the following final so typical, that I just had to annotate it:
