Following the game live on Internet Chess Club (ICC) last night , i thought that the game would end witha draw but somehow Wang Yue managed to penetrate Svidler position and won in the rook+4 pawn vs bishop+ 5 pawn endings.

According to Fundamental Chess Endings by GM Karsten Muller and IM Frank Lamprecht In endgame with rook + Pawns vs bishop with pawns ( on both wing), the superiority of the rook is usually even greater with pawns on both side of the board (though if the side with the bishop has dangerous passed pawns, matters are not so clear)

According to GM Lev Alburt, in this type of endings, the rook beats the bishop in the majority of the cases. The defender has his best chance when all the pawns are located on the same side of the board. The more the pawns, the rook has more chance to win.

Also in this type of ending, the defender often but not always, want his own pawns on the opposite –color squares than those covered by his bishop, in order to prevent dangerous penetration by his opponent king’s.
