Interfering

Undermining an enemy piece can be done in several ways. We’ve already practiced with exchanging pieces and deflection.

Now, we will look at another way to undermine a piece’s defense: interference. An interference move interrupts the line between the defender and the attacked piece. You can do this by putting one of your pieces or a pawn between the enemy piece and its defender. Or by making a threat that causes your opponent to move one of his pieces there.

Interference is a tactic that seldom occurs, due to the multiple conditions that must be satisfied. Still, it is useful to practice interfering because it clearly illustrates the importance of pieces teaming up. It also teaches you how to profit from disturbing your opponent’s piece cooperation!

What do you have to do?
Eliminate the defense by cutting off an enemy piece from its defender.
