P Is For Pin X

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 June 12th (https://cschessnews.blogspot.com/2021/06/d-is-for-discovery-ix.html).  

The second kind of tactic in the DROP Method is Removal, which I revisited on June 19th (https://cschessnews.blogspot.com/2021/06/r-is-for-removal-x.html).  

The third kind of tactic in the DROP Method is Overload, which I revisited on June 22nd.

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 26th Annual Colorado Springs City Chess Championship:  Qualifier.  Will Wolf was trying to persuade me that his game was all theory.   I just looked at this position and said, "Oh, yeah, from the book of Pretty Little Pincushions."  There are so many Pins or potential Pins in this position that it might be hard to choose which one to exploit.  The Black Queen is pinned to the King (Absolute), and the Black Night is pinned to the Rook (Relative).  Can you find the one that works?

O Is For Overload X

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 June 12th (https://cschessnews.blogspot.com/2021/06/d-is-for-discovery-ix.html).  

The second kind of tactic in the DROP Method is Removal., which I revisited on June 19th (https://cschessnews.blogspot.com/2021/06/r-is-for-removal-x.html).  

The third kind of tactic in the DROP Method is Overload.

Overload is a chess move that attacks a target.

The Overload is played when the player creates a threat on a target that cannot be defended.  The classic example is choosing a target and piling more attackers on it than supports the defender can muster.  When the number of attackers is greater than the number of supports, material can be won through a series of captures.  Each capture creates a new target until the final support is exhausted and an unguarded target appears.

However, the Overload is, perhaps, the broadest kind of tactic.  Not only does it use multiple attackers on one target, but also it uses a single attacker on multiple targets.  The idea is the same:  gain a target than cannot be defended.  So, most players will become familiar with the different types of Overloads:

  • Battery (Overload with multiple attackers on a file or diagonal)
  • Fork (Overload with multiple targets by the Knight)
  • Double Attack (Overload with multiple targets by the other pieces)
  • Over-Worked Piece (Overload with multiple targets)
  • Skewer (Overload with multiple targets where a high value piece is in front)

Here is a position from the Colorado Springs Chess Club's Sunday Night event, Removal Rapid Online.  Ayush Vispute was eager to get his first gold medal in our Corona Chess Olympics and went for a sacrifice to expose my King.  I thought I had it defended when I got careless and boxed in my Queen.  Now, my only hope was to create an entry into LM Brian Wall's Burden Award contest for dropping your Queen but still winning.  I had my chance in this position, but I missed it.  See if you can do better?

R Is For Removal X

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 June 12th (https://cschessnews.blogspot.com/2021/06/d-is-for-discovery-ix.html).  The second kind of tactic in the DROP Method is Removal.

Removal is a chess move that attacks a support.

The Removal is played when the player stops an opponent's piece from supporting the actual target.  The supporting piece will typically be of an equal or lesser value than the attacking piece.  However, the Removal can give up material, as the protection on the real target is now gone and creates a second attack that cannot be defended.

The target can be the King (Mate threat), a valuable piece (Material threat), or even a square (Mobility threat).

Different types of Removals are referred to by different names, but the idea is the same:  The support of the target is removed.  Here are some names for the different types of Removal:

  • Clearance (Removal by passing support)
  • Deflection (Removal by forcing support to move)
  • Interference (Removal by interposition; Interception)
  • Undermining (Removal by capturing support; trade)
  • Sacrifice (Removal by capturing support; Exchange; Greek Gift, Desperado)

Here is an example from the Colorado Springs Chess Club's online, Sunday-night tournament, Discovery Rapid Online.  Black has just forked White's Rooks with 31...Ne3.  But White has a Removal tactic to avoid the loss of material.  Can you find it?

2021 City Speed Chess Championship


With the club closed at the beginning of the year, we were unable to hold our traditional January event, the Colorado Springs City Speed Chess Championship.  It began in 1996 and has been an annual tradition since then.  Since COATI is letting us use their site, we decided to keep the tradition going and motivate the President to get the plaques updated.

Eleven players have won the title.  You could be number 12!

D Is For Discovery 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 opponents 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.

Discovery is a chess move that attacks with two pieces.

The Discovery is played when a player is going to make an attack with the piece that he moves, but also he will make an attack with another piece that was blocked by the piece that he moves. When the Discovery is successful, the opponent can only avoid one of the attacks. This means that the other attack will gain material or mate. The second attack is often a check on the King, which is called a Discovered Check.

"Discovered check is the dive bomber of the Chessboard."
(Reuben Fine)

Here is a position from a game played between Mark McGough and Rhett Langseth in the Colorado Springs Chess Club's Sunday night, online event, Cancel Chess.  There are actually two good moves here.

See diagram on blog

Mark discovered one of the moves and was certain that he had blown-up the competition with his 300-point upset in the final round and was sure to be awarded a medal for his valor.  Unfortunately, he was stunned by the discovery that my guns had knocked him out of the sky and taken his place on the medal stand.

Lyrics from Iron Maiden's Aces High

Move in to fire at the mainstream of bombers
Let off a sharp burst and then turn away
Roll over, spin 'round to come in behind them
Move to their blindsides and firing again
Bandits at eight o'clock move in behind us
Ten ME-109s out of the sun
Ascending and turning our spitfires to face them
Heading straight for them, I press down my guns...

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 (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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 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.

O Is For Overload 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 (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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 (https://cschessnews.blogspot.com/2020/05/d-is-for-discovery-viii.html).  The second kind of tactic in the DROP Method is Removal, which I revisited on May 17th (https://cschessnews.blogspot.com/2020/05/r-is-for-removal-ix.html).  The third kind of tactic in the DROP Method is Overload.

Overload is a chess move that attacks a target.

The Overload is played when the player creates a threat on a target that cannot be defended.  The classic example is choosing a target and piling more attackers on it than supports the defender can muster.  When the number of attackers are greater than the number of supports, material can be won through a series of captures.  Each capture creates a new target until the final support is exhausted and an unguarded target appears.

However, the Overload is, perhaps, the most broad kind of tactic.  Not only does it use multiple attackers on one target, but also it uses a single attacker on multiple targets.  The idea is the same:  to gain a target than cannot be defended.  So, most players will become familiar with the different types of Overload:

  • Battery (Overload with multiple attackers on a file or diagonal)
  • Fork (Overload with multiple targets by the Knight)
  • Double Attack (Overload with multiple targets by the other pieces)
  • Over-Worked Piece (Overload with multiple targets)
  • Skewer (Overload with multiple targets where a high value piece is in front)

Here is a position from the Colorado Springs Chess Club's Corona, No Lime Rapid Online tournament. Since it is Father's Day, I chose one of my losses.  This one came at the hands of LM Brian Wall.  Sort of.  Part of the reason I lost was my blindness to the Overload tactic, which I finally saw on my fourth attempt.  See if you can spot it right away.

R Is For Removal 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 (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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 (https://cschessnews.blogspot.com/2020/05/d-is-for-discovery-viii.html).  The second kind of tactic in the DROP Method is Removal.

Removal is a chess move that attacks a support.

The Removal is played when the player stops an opponent's piece from supporting the actual target.  The supporting piece will typically be of an equal or lesser value than the attacking piece.  However, the Removal can give up material, as the protection on the real target is now gone and creates a second attack that cannot be defended.

The target can be the King (Mate threat), a valuable piece (Material threat), or even a square (Mobility threat).

Different types of Removals are referred to by different names, but the idea is the same:  The support of the target is removed.  Here are some names for the different types of Removal:

  • Clearance (Removal by passing support)
  • Deflection (Removal by forcing support to move)
  • Interference (Removal by interposition; Interception)
  • Undermining (Removal by capturing support; trade)
  • Sacrifice (Removal by capturing support; Exchange; Greek Gift, Desperado)

Here is an example from the Colorado Springs Chess Club's online tournament.  Black has just sacrificed his Rook.  White is suspicious that this maybe an attempt at a Removal and finds the best response.  Can you find it?

D Is For Discovery 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 (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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.

Discovery is a chess move that attacks with two pieces.

The Discovery is played when a player is going to make an attack with the piece that he moves, but also he will make an attack with another piece that was blocked by the piece that he moves.  When the Discovery is successful, the opponent can only avoid one of the attacks.  This means that the other attack will gain material or mate.  The second attack is often a check on the King, which is called a Discovered Check.

"Discovered check is the dive bomber of the Chessboard."

Reuben Fine

Here is a position from game 50 played between myself and my dad in our email match.  There are actually two good moves here.  I found the immediate Discovery, but see if you can find the delayed Discovery too.

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 (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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 (https://cschessnews.blogspot.com/2019/04/d-is-for-discovery-vii.html).  The second kind of tactic in the DROP Method is Removal, which I revisited on May 14th (https://cschessnews.blogspot.com/2019/05/r-is-for-removal-viii.html).  The third kind of tactic in the DROP Method is Overload, which I revisited on May 29th (https://cschessnews.blogspot.com/2019/05/o-is-for-overload-viii.html).

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.

D Is For Discovery VII

Game Of The Week


A couple years back, I came up with a method to organize chess tactics.  I called it the DROP Method (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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.

Discovery is a chess move that attacks with two pieces.

The Discovery is played when a player is going to make an attack with the piece that he moves, but also he will make an attack with another piece that was blocked by the piece that he moves.  When the Discovery is successful, the opponent can only avoid one of the attacks.  This means that the other attack will gain material or mate.  The second attack is often a check on the King, which is called a Discovered Check.

"Discovered check is the dive bomber of the Chessboard."

Reuben Fine

Here is a position from a game played between Chris Motley and Asher MacEnulty in the Cabin Fever Reliever from the Colorado Springs Chess Club's Tuesday night April tournament.

Black to move

The Discovery is played by capturing the Bishop on h6.  This move is an attack on the White King, the Discovered Check.  White has to move the King.  However, when the Discovery is added into the mix, the attack is even better.  The Bishop capture reveals an attack on the White Queen.

The first attack is a capture and check of the King.  The second attack is a capture of the Queen.  White has to defend the King by the rules of the game.  The Bishop and Queen loss puts Black back in control of the game.

So, by just being observant, a player can find these Discovery opportunities and salvage a bad position.

P Is For Pin VII

Game Of The Week


A couple years back, I came up with a method to organize chess tactics.  I called it the DROP Method (https://cschessnews.blogspot.com/2012/03/drop-method.html).  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 10th (https://cschessnews.blogspot.com/2018/04/d-is-for-discovery-vi.html).  The second kind of tactic in the DROP Method is Removal, which I revisited on May 14th (https://cschessnews.blogspot.com/2018/05/r-is-for-removal-vii.html).  The third kind of tactic in the DROP Method is Overload, which I revisited on June 18th (https://cschessnews.blogspot.com/2018/06/o-is-for-overload-vii.html).

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. Erasmus Eskeldson, who is closing in on his 50th standard-rated tournament game, got his Bishop pinned to his Queen.

However, Erasmus realized that a Pin against the Queen is not Absolute.  It is a Relative Pin.  The pinned piece can move, and, in this case, it can create a Discovery to get out of the Pin and win material!
