P Is For Pin

Posted by Paul Anderson on May 15, 2012 at 11:55 PM

Game Of The Week

  

Last time on the DROP method of tactics, I talked about Overload (http://cschess.webs.com/apps/blog/entries/show/14420236-o-is-for-overload).  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. 


The fourth category in the DROP method is Pin.  See, D is for Discovery, R is for Removal, O is for Overload, and P is for Pin.  Together the 4 kinds of tactics spell DROP and should be broad enough to cover all the different tactical ideas out there.  If you have a tactic that you are not sure where it would fit, let me know and I will update the system if necessary.

 

The Pin is possibly the most common and fundamental chess tactic.  Mark McGough told me that pins comprise close to 80% of all tactics played.  The pin is probably the first tactical idea a chess player learns and often plays it without even knowing it.  Even your opponent will set up pins for you without even knowing it. 


The idea of Pin occurs when a higher value piece is caught behind one of his own lower value pieces.   The lower value piece cannot move without the higher value piece being captured with a loss of material.  Therefore the lower value piece is stuck (as if with a pin) and open to attack. 


There are three kinds of pins. 


The Absolute Pin has the King as the higher value piece and causes the lower value piece to remain absolutely unmovable until the pin is released, due to the rule against allowing a King check. 


The Relative Pin involves any other higher value piece besides the King. 


The Cross Pin is rare and combins two pins on the same piece. 


The key to using Pins is to recognize them when they occur and to find a second threat to capitalize on the piece that cannot move.  It can be as simple as attacking the pinned piece with a pawn.

 

Here is an example from one of my recent games at the Wednesday Night Panera Tournament.  I have played Richard Brown twice.  Both times were at the Wednesday tournament, and both games revolved around Pins that Richard set up against himself. 


When your opponent sets up the Pin, it is easy to miss it, as I did in this case.  In playing 21...Re7, Richard set up the Pin on his C Rook.  The C Rook becomes the higher vaule piece caught behind the lower value pawn.  If you just remove the C Pawn from the game, white would use his Overload to capture the C Rook or trade Rooks and win the B Bishop. 


Of course, you cannot just remove pieces from a game like that.  However, now that you know the Pin is there, can you find a second threat?

 


 

If you found Nd6!, you did better than I did in this game.  However, don't worry if you did not find the tactic.  Tactics flow from good positions.  I often miss tactics in games I win.  It is not my strength.  Plus, this Pin is not easily released.  I later took advantage of this same Pin to win a pawn, go up 2 pawns, and push on for the victory.
