P Is For Pin IX

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 May 10th (  The second kind of tactic in the DROP Method is Removal, which I revisited on May 17th (  The third kind of tactic in the DROP Method is Overload, which I revisited on June 21 (

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 pin is mightier than the sword.”

Fred Reinfeld


The Pin works by threatening a low value piece that has a higher value piece (or an unguarded 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 Sunday-night event:  CSCC Killer Bloodgood Rapid Online.  Alex Bozhenov was going for his first medal in our online summer games and trying to stay unbeaten in Rapid time control.  However, LM Brian Wall was trying to take the lead in the medal count and grabbed a Pawn in the opening.  Alex had a golden shot to win the game but picked the 2nd best move and ended up with the silver.
