KLA Chess Club is a part of Keiller Leadership Academy of southeast San Diego, a Title 1 Charter school. Chess is offered as an everyday class for students.

The following lesson is taken from the KNSB Dutch Training System by Brunia/Wijgerden.

Goal of the Lesson: Learning how to defend against specific kinds of attack.

There are several ways a player can defend against the Double Attack:

1. Moving away

2. Protecting

3. Capturing (including exchanging)

4. Interposing (x-ray)

Below, the King is in check by the Queen, which is also threatening the Knight. However, white can defend by interposing the knight to b3, which is defended by the c2 pawn.

In this diagram below, it's black's turn to interpose the Queen on g7.
Below, two of black's pieces are under attack. Black can save himeslef by playing...Ra7. The rook moves away and protects the Knight in the process.
Below, the f5 knight is in trouble and a threatened checkmate  on f1. An exchange of queens helps relieve the pressure after 1. Qh4+.
Below, White is threatening a back rank mate with the Queen on a7 and the rook on e1. In addition, the black knight on a5 is threatened. How can black defend against this?
A counter-attack (defend and then attacking position) is another great way to defend:
Below, it seems as though black has two pieces being attacked . However, black pins the White queen with 1...Rb6.
Below, black uses a check to allow both pieces to escape:
Solve the puzzles below using the concept of counterattack.
Below is an example of of counterattacks involving mate. White defends against the double attack with 1. Rc1. This move threatens mate on c8. Black must deal with this threat first, giving White time to rescue his bishop.
Try and solve the puzzle below. Hint: black threatens mate to bring his pieces to safety.

Sometimes, counterattacks involve other types of combinations. Below, Bxb3 is an example of 'capturing + material'.
Search Strategy

1. Which of my pieces is in danger?
2. Can I capture (exchange) the attacker?
3. Can I interpose, protect or move away?
4. Is there a counterattack possible?
5. Can I give check with an attacked piece, can I pin an attacking piece or can I threaten mate?
