This is an article written by the RCA guest coach FM Zaur Tekeyev.
It’s well known that endgames with opposite-colored bishops tend to be drawish. Sometimes even having a few extra pawns can’t guarantee a win. But what about middlegames? Are opposite-colored bishops a sign for a draw in every position?
The answer is no. Opposite-colored bishops in middlegames are in favor of the attacking side. The point is that you can use your bishop to put pressure on those squares that the enemy bishop can’t defend. So basically it gives you a material advantage on the squares of your bishop’s color. Recently, I noticed that current World Champion Magnus Carlsen had a few good examples of such middlegames and so, in this article, I would like to illustrate the concept by using his games.
Even though at the time the next game was played Carlsen was only 14 he already was a very good grandmaster. And even though the position was quite equal he managed to outplay his opponent quite convincingly.

Black to play
As you can see White has a pawn majority on the queenside but there’s no possibility to create a passed pawn in the future because everything will be easily blocked on the dark squares by Black’s bishop and queen tandem. While Black’s pawn majority on the kingside is very mobile and in the future it caused a lot of headaches to White’s king. Also, let’s point out that there’s a weak point in White’s position on f2. So young Magnus first focused on that weakness to make White’s pieces more passive and only then started trying to move his pawns on the kingside. Let’s see how the game continued:
But you may argue why did I say that the position was equal if Black won so easily? Fair point. But that was the objective evaluation of the position. The thing is that White had to be very careful to make a draw. More precise maneuvering could make Black’s task much more difficult. Or, for example, on move 40 something like h2-h4 or h2-h3 was interesting with the idea to stop Black’s h-pawn from moving further.
In the next position, Black’s pieces were more active than their counterparts so Magnus had to be very careful not to lose the game.

White to play
Would you try to exchange all the pieces and try to make a draw in the endgame? Magnus found the best way to defend – to attack! After pawn sacrifice, White’s pieces became really active and now Black had to defend!
Previous games showed us that it’s good to attack in positions with opposite-colored bishops even in endgames. In the next game, we will see how strong the attack can be in a full of pieces position.

First, the transition into a position with opposite-colored bishops was a great decision by Carlsen. White cleverly decided to complicate things and made some sacrifices but as the main line I decided to show you what Magnus wanted to achieve and Maxime tried to avoid.
