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 May 3rd (http://cschess.webs.com/apps/blog/show/43953073-d-is-for-discovery-iv). 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 an email match I played with my Dad. He has just played a Removal. By moving the Rook to b1, he has appeared to drop the piece. However, the Knight is a support for a key square: b5. If the Knight goes to take the Rook, then the Bishop can play Bb5+ and regain the Rook. What should Black do?
Black to move
See the diagram and answer here:
With Black ahead by a Pawn already, there are a couple of good choices. Just trading Rooks is good for Black. However, I realized I was going to lose my Rook anyway. So, I decided he should go out in a blaze of glory: a Desperado!
A Desperado is the name given to a piece that sacrifices itself to gain a small amount of material since it was going to be captured anyway. It is a type of Removal.
I played 34...Rxf4+ to gain a Pawn before winning the White Rook. However, it might be better to not play the Desperado and just quickly round up White Passed Pawn on a3 first.
"The passed Pawn is a criminal, who should be kept under lock and key. Mild measures, such as police surveillance, are not sufficient."
