Teaching Pin to Kids

Pinning and winning.

In chess, a pin is a situation brought on by an attacking piece in which a defending piece cannot move without exposing a more valuable defending piece on its other side to capture by the attacking piece.

Looks complicated, let me explain it with the help of following example




On your right hand side
- Black Rook is the attacker
- White Bishop is defender (Defending king by blocking/interposing)
- White King is the more valuable piece than Bishop.

Therefore Bishop has lost its mobility called PIN. This is called absolute pin as bishop move would be ill-legal move.

While on your left hand side
- Black Rook is the attacker
- White Bishop is defender (Defending queen by blocking/interposing)
- White Queen is the more valuable piece than Bishop.

But here Bishop has some mobility as moving bishop is not ill-legal but not advisable. It is called relative pin.

Pin is possible against square too. Here is an example...

 Here queen on d2 can't move because of checkmate threat on d8.

On next article we will look at getting benefits out of the pin with the help of classical games.
