I focus on the following themes:
- double attack
- exposed king
- defensive move
- Min rating: 1500
- Max rating: 2000
I have taken a peek at the higher rated problems. They are higher rated because there is more going on in the position. There are a lot of seemingly attractive lines which only distract you from the solution. It doesn't make sense to worry about problems with a higher rating than 2000, before you master everything thoroughly that is below 2000. Above 2000 it are the same themes, but there are more themes compacted within a single problem.
Currently I do problems with a rating between 1780 and 1830. The common theme is fork/double attack. What I try to do is to recognize problems with the same characteristics. These characteristics aren't commonly known.
I suspect that these newly defined categories aren't limited to double attacks only. The themed problems make it easier to recognize the characteristics of such new category.
A new category I recently discovered, are problems where the opponent takes a minor piece of you. In stead of taking back immediately, you start a duplo attack of your own, threatening a piece with a higher value.
|White just played Nxe6 (taking the bishop). Black to move|
4r3/kp3pB1/p2Rb1p1/4p2r/3N4/2R5/PPP2n1P/2K5 w - - 6 1
White is a minor piece ahead. He has just captured the bishop on e6. In stead of taking back, you start a double attack of your own. Under what conditions is such action profitable?
- The first condition is that one of your targets has a higher value than the piece that was just captured.
- The second condition is that your target has to be unprotected
- The third condition is that your opponent needs a tempo to get his high valued target into safety
- The fourth condition is that white has no double functional move at his deposal.
Cluthering my Short Term Memory slots
This type of problems will typically overload my Short Term Memory slots. Taking stock of the values of the pieces while trying to remember in which branch of the tree I am will typically cause an administration shutdown. The problem will take ages to solve OR I go for the wrong solution.
If you take a close look at the problem, it is not exactly rocket science. The decisions to be made are simple and straightforward when you know what to look at.
By exploring these new categories, I hope to simplify my chess thinking. These counter threats aren't limited to double attacks only, of course.
