D Is For Discovery VI

Posted by Paul Anderson on April 10, 2018 at 4:55 PM

Game Of The Week


A couple years back, 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 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 Larry Osborn and  Ayush "Panda" Vispute in the March Swiss 90 from the Colorado Springs Chess Club's Tuesday night monthly tournament.


Black to move


See the diagram and answer here:

The Discovery is played by moving the Rook to c1.  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 unstoppable.  The Rook move reveals an attack on the White Bishop.


The first attack is a check of the King.  The second attack is a capture of the Bishop. White has to defend the King by the rules of the game.  The Bishop has been lost along with the hopes of winning a close endgame.


So, by just being observent, a player can find these Discovery opportunities and save that point.
