P Is For Pin VIII

Game Of The Week

A couple years back, I came up with a method to organize chess tactics.  I called it the DROP Method (   The DROP method is an acronym for the basic kinds of tactics.  It is meant to remind you not to drop your pieces and help you get your opponent to drop theirs.

I said that the DROP Method was a work in progress, and it was.  So, I thought I would revisit each of the four kinds of chess tactics to provide more examples.  The first kind of tactic in the DROP Method is Discovery, which I revisited on April 8th (  The second kind of tactic in the DROP Method is Removal, which I revisited on May 14th (  The third kind of tactic in the DROP Method is Overload, which I revisited on May 29th (

The fourth kind of tactic in the DROP Method is Pin.

Pin is a chess move that immobilizes an opponent's piece.

The Pin is different from the other kinds of tactics in that it does not create multiple threats.  Its main function is to prevent a piece from moving.  A Pin on a target allows that target to be attacked by a lower value piece.  A Pin on a support allows the capture of the piece the support is guarding.

"The defensive power of a pinned piece is only imaginary."

(Aaron Nimzovich)

The Pin works by threatening a low value piece that has a higher value piece (or an ungarded piece) behind it.  The low value piece is stuck (as if with a pin) to the higher value piece due to the loss of material should the low value piece move and allow the capture of the higher value piece.

If the higher value piece is the King, the low value piece is absolutely immobilized, as the rules of Chess do not allow moves where the King could be captured.  Otherwise the Pin is relative, as the opponent can actually move the low value piece if he is willing to accept the loss of material.  The other types of Pins are rare:

  • Absolute (Pins a target to the King)
  • Relative (Pins a low value target to a higher value piece)
  • Cross (Multiple Pins on one piece)
  • Cross-check (blocks check and counter-checks)

Here is an example from the Colorado Springs Chess Club's Tuesday night event:  July Mating Game.   Alex Bozhenov created the best example of a Pin in his game with Joel Brown this night.  While the Black Pawns on the 3rd rank make this position dominating for Black, taking advantage of the Pin on g2 is by far the best move.
