Bronstein on chosing a move
This Positional Strength of a position is something that many people do not understand and appreciate.,not only players of average strength , but even masters. How many games have been lost by attacks floundering on solid defenses! The problem is that on the board, as on a diagram, one sees only the outward aspect of the position -- the placing of the pieces-- and the interconnections between them are concealed from view, they are open only to our mind.
So,each time, when it is your turn to move, you are obliged to make a single choice out of many possibilities. In so doing you will rely on your basic information-your knowledge and experience. suitably systemised and in the current information- the position on the chess board and the series of preceding moves. You will be guided by your ideas,tastes,intuition, and of course, calculation a few moves ahead. But not too many moves ahead. Do not believe those who talk about calculating ten moves ahead. This applies only to strongly forced variations ,where to each move there is only one or two replies.,Branched variations do not usually lend themselves to direct calculation. One of the greatest chess thinkers, Richard Reti,to a questions as how far he calculates variations ahead replied :One move ahead. By this he expressed an idea which in modern terminology would be stated roughly as follows:
"The range of possibilities in chess is endless, the range of reality is unambiguous, and in such conditions the choice of a move cannot be based on the calculation alone"
In the majority of lengthy combination achieved by the author, the basis was not just calculation , but a belief in the logical strength of a position, in the readiness of resources and in their harmonious coordination. (TAKchess note take a look at move 14 by white, I imagine it made in this way http://www.chessgames.com/perl/chessgame?gid=1033895 )
The choice of a move is a comparison of resources and aims. You must ask each piece what it can usefully achieve on its own, what help it requires from the other pieces, and in what way it itself is prepared to help them. All this must be done as quickly as possible, in order to also use sensibly your time.
Now this guy is deep and somewhat rambling. I have been waiting for myself to reach a level where I can better appreciate his writing. I think that time is now.

The Validity of Ct-art
I wonder if part of the artifical feeling that people get is that some of the position are varied from existing positions so that they can have tactics from both the black and white side. Maxim Blokh wrote a problem book 600 combinations where the positions are playable for material advantage checkmate from both sides. Maxim Blokh the creator is am accomplished coach and correspondance player.
I am happy with the problem set provided by ct-art. Most are mating problems and address all major mating themes. I feel it is important to drill on all the mating themes as the threat of mate often sets up free material. Alot of what I learn is similar to playing pool. You make a shot but also try to have a good "leave" to set up the next shot. Alot of what I am learning is moving my pieces in a mating net or tactical net so that you properly set up the next move.
If I had the ability to direct the develop roadmap for Ct-art 4. I would like to have the ability to mask the ones that I got correctly and automatically do a subset of those I got wrong. I would also like to be able to do a circle of the 5 X5 problems. I would also like to have a bookmark feature where I can create a playlist of problems .
I also wish that someone would create a Ct-art style program from the problem set in sharpen your tactics. Most of those games are from master games with alot of interesting play.
I ask that any readers who own Ct-art leave a comment as to 1) What they think of the problem set 2) what would they do to improve it.

Reflections from the Takchess Infinite L20 Circle Tour

A lesson in here -WTM
WTM- The takeaway lesson for me is always calculate Back Rank Mates when the King has no luft.
The game (composition?) with interesting commentary is at this link.
This is from Torre of the amazing windmill fame.
My feeling is even if this is analysis he very possibly could find these moves otb given his strength.
Friday continued slow L20 circle 97%- 290

WTM- an interesting position
Some chess tactical problems are just too cool. Here is one with white to move. Many forces are in balance here.
Source: Understanding Chess Tactics by Weterschnik page 19.
addon note: as DG noted the correct move is g4. I find this puzzle to be aesthetically pleasing.
The factors in balance are White desire to put the rook in the backrank is stopped by the queen. The pawn in front of the queen ,the discoverer opens up a discovered attack against the queen as well as interferes with the protection against the back rank mate. Discovered attack in order to be effective normally has the discoverer ( the piece which creates the discovered attack) do something useful such as attacking another piece, delivering a check, blockading.

Presented for your Consideration
Presented for your consideration, the following is not an example of perfect play or dry opening theory but a tale. A tale of two knights Cratercat and Takchess meeting on the virtual 64 and the struggle that ensues. It is a tale of overly aggressive play, inactive pieces, a wild save ones life king dash across the board , a pawns lust to expand, frantic attempts to kill or be killed, unfortunately for your favorite blogger it is also a tale of missed opportunity....... In both these diagrams black to move wins according to Fritz in a mating net.

A cool tactical game
Tuesday, May 01, 2007
I am doing a slower circle where I blunder check everything and calculate everything fully to quiescence before moving a single piece.
I also hope to develop an observation check list of clues to tactical situations based on positional considerations. ie: When I have 2 bishops and one controls an open diagonal in front of a queen. Check for boden mate/crisscross mates and calculate Queen Sacks to set this up.
Scoring around 90% on level 20 which needs improvement so I am going back and do a very slow level 10 and then a slow level 20.
I have started to play the Scandinavian Defense due to poor experiences against good Ruy players like Keystor . Playing 3 ...Qd6 as in this collection . I know about 3 moves deep into the opening and am just at this point trying to put my pieces on good squares. Had a big rating drop on playchess initially but it now appears the bleeding has stopped.
