P Is For Pin II

Posted by Paul Anderson on July 20, 2013 at 5:45 AM

Game Of The Week


Last year, I came up with a method to organize chess tactics.  I called it the DROP Method (http://cschess.webs.com/apps/blog/categories/show/1378181-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 clarify and improve the method: 


 

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 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 I found while going through the database of my 708 USCF-rated chess games.  I noticed that I had recently played my 700th tournament chess game.  Since these round numbers often have special events that coincide with them, I decided to look over my Septcenchessial to see if it deserved fireworks and a parade.


It did not.


I tried to play a "bishing pole" attack I had learned from LM Brian Wall's emails (http://games.groups.yahoo.com/group/BrianWallChess/), but Eugin was not interested in my bait.  Of course, the bishop as bait seems less effective than the knight.  It is hard to just ignore the knight like Petrosian found out against Tal in this line they analyzed for GM Pal Benko when he played GM Bobby Fischer.

After my "bishing pole" attack failed, I reorganized my pieces until I found myself in this position.  There are a number of good moves here but see if you can find the tactical shot.   It is white to move.



I decided to take advantage of the Pin on the c6 Pawn.  The lower value piece (Pawn) is stuck to the higher value piece (Queen) because of the Rook on c1.  So, I took the b5 Pawn with my Queen even though it is guarded by another Pawn.  This is a Relative Pin as Eugin can move his Pawn and capture my Queen, but since he is losing the Pawn either way it is best to keep his Queen on the board.
