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, which I revisited on March 14th (http://cschess.webs.com/apps/blog/show/43172189-d-is-for-discovery-iii). 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:
Here is an example from a game in the April Swiss at the Colorado Springs Chess Club. Now that I have become a tournament director (TD), I can collect the score sheets and find lots of examples of tactics like this one.
NM Richard "Buck" Buchanan has been an officer of the chess club and a TD since I have been playing rated chess. He encouraged me to get certified as a club TD. Perhaps, the reason he wanted me to become a TD was because I would have access to his wins over other people and less likely to publish my victories over him. Buck has suffered the most from my policy of publishing all my upset wins.
Well, he didn't quite get the win in this game, but he should have. Here he finds the killer tactic but misses the subtle endgame win. See if you can get both.
Black to move
See the diagram and answer here:
The Removal is played by checking the King (43...Bb4+)! The King has no way to guard the Knight anymore and has to capture the Bishop. The Black King captures the Knight and is still in position to stop a Passed Pawn on the King-side. However, the White King is unable to stop a Passed Pawn from Promotion with the 3 to 2 Pawn Majority.
"The passed Pawn is a criminal, who should be kept under lock and key. Mild measures, such as police surveillance, are not sufficient."
