KLA Chess Club (Keiller Leadership Academy), is a Title I, K-8 Charter School located in southeast San Diego. Chess class has been implemented as an everyday, in school class for middle school students.

For more information about our school, visit our website  or learn more about the KLA Chess Club,

The following lesson is taken from the Dutch KNSB training series by Rob Brunia and Cor van Wijgerden 

 

A typical pin can yield a piece in material as shown below:

A pin can also used with a piece and key square:

In the diagram  below, white has pinned the Knight to the King, but is it enough to win a piece or does the rook need help?


Below, how can white win a piece with some help?

Can you identify the pin below? Remember a pin doesn't alway have to be 2 pieces. A pin can be to a square as well.

Below, black to play, can you identify the pin? What is the best plan of attack for black?

Unsuccessful vs. successful attacks on a pin:
Summary: Attacking a pinned piece is insufficient when :
a) The attacking piece is too valuable
b) A counterattack is possible
c) The front piece (pinned piece) can protect the back piece.
Search Strategy:
1. Which piece is pinned?
2. Can I attack this piece once more (using the 'cheapest' piece)
3. After I have playe dmove move, does the opponent still have a defence?
