Silman!?
First, he talks as if everyone visualizes and calculates deeply and accurately. No problemo! ;-)
Second, re: "Rules of Combination Recognition":
- I think he needed to add immobilized pieces and pawns to his list.
- I wonder if he needed to add inadequately guarded squares/lines as well. An easy example of that is when someone is down material in the endgame, but trades down further to reach a King vs King + Rook pawn + wrong Bishop. If the lone King can make it to the safe corner, it's a draw, i.e. the corner square was inadequately guarded.
- Personally, I never see tactics via thinking his way. In 1/100 moves, I just get it that there is a tactic/combination for that move. It just pops up.
- I wonder, what if he had an earlier book with a large collection of tactics problems in two sections: one section of problems with one or more "Rules of Combination Recognition" weaknesses already in the position, another section of problems without immediate weaknesses where you need to create them. Only after getting through all those problems would you read his next books, having a foundation to build on. Just a thought.
He has organized and collected many important chess principles, but it comes across to me like he invented nearly all of it. He seems unrealistic about how fast chess principals translate into know how. Lacking all the "nuts and bolts", beginners are expected to go from positional observations to putting together a plan. Then he is insensitive and critical when his students get it wrong, which unfortunately reflects on him as a teacher. Taking one of the problems in the back as an example, this problem's answer is to make a prophylactic move to prevent a center pawn advance. The mistake done in the game (instead of that prophylactic move) was to castle. His advice of "castle early" is clear earlier in the book, and it's easy to imagine that castling makes sense there. No mathematical system to weigh decisions like these is presented, but practically expected. It's all about how obvious it is to him, like 1 + 1 = 2.
Anyway, strong players have been around for decades, long before Silman wrote anything. I guess it's a case of taking what you want, and leaving the rest behind.

Are We Saying It Right?
- recognize tactical possibilities in a position,
- accurately calculate and visualize resulting positions,
- and assess every possible response that could refute the line.

Fundamental Checkmates
I hardly can imagine that my work here is original, but if it is well, cool! I don't even know if it could rightly be called a theory, but that's a place to start. Anyway here is my Theory of Fundamental Checkmates:
All normal checkmates are one of eight patterns.
All double-checkmates are one of five patterns composed of two normal checkmates.
Addendum Mar 4, 2005:
Examples:
This picture shows the 8 normal checkmates using Black pieces instead of capital "X"s.
The next 3 pictures use the same rook mating pattern. In each, the "X" squares are handled differently: first by White pieces controlling those squares, then by a mixture of Black pieces occupying those squares and White pieces controlling those squares, and lastly by a mixture of Black pieces occupying those squares, White pieces controlling those squares, and the Black King on the edge of the board.
Completed circle 4 of problems 121-160.

Endgame Stuff Part 5
I have attempted to make my annotation simple enough for even me to understand! I am a beginner in writing them, and would appreciate any comments about it from those more experienced annotators out there in blog space.

Endgame Stuff Part 4
I think my style is positional and I am more likely to trade pieces than a strong tactical player. So... I do study the endgame. I figure doing 30-40 endgame problems per every 1000 tactics problems ought to be ok ;-).

Hanging Pieces
-=-=-=-=-
Take a look at it the other way:
Visualize two people at chess board in the starting position with a single spectator watching. You can hear the thoughts of the spectator. This spectator has been brain-washed into thinking hanging pieces is actually good. Oh, and hanging material normally freaks him out!
Only four pieces hanging... got to get things going here.
1. e4 e5
Hmm only six now...give me more!
2. Bc4 Bc5
Ah ten men hanging, it's looking good now.
All seriousness aside, my point is the end position is ok.
-=-=-=-=-
Anyway, doing tactics problems repeatedly has driven home that occasionally you must hang your pieces. I am writing down the following note in hopes I start checking for those types of moves.
"Sometimes hanging a piece is the best move."

My Chess Mistakes, Vol. 1
Some mistakes seem happy to crop up again and again, no matter how many times one might see it. To battle my own beginner tendencies, I began writing down notes. This note still holds true a year later:
"Bishops on the move leave b and g pawns vulnerable, and the c pawn becomes a target if the Queen moves very far."
Pretty simple, huh? Well, I suppose it is. If only I could remember it.
I was Black here:
(Actually black might have a winning or at least drawn position is 22 ...d5)
Not seeing the Qxb7 threat was my mistake. I have been calling this and other similiar glitches "after the move" mistakes. If you want, leave a comment on whether or not White can safely take the b pawn.

Mind Wide Open
- My defensive brain part is boring. If I fail to include that part, I start hanging material. And, if I overemphasize that, I end up with a passive position that is just begging for someone to take apart. Nonetheless, it seems accurate 85% of the time.
- My tactical brain part seems to only work if I visually break away from the position, get quiet, which is no easy task, and the let some sort of invisible gears start moving. It seems to get the right answers 90%+, and is not so depth limited, but when it comes up with the best move I almost feel like someone else got to play. I suspect those players who rise quickly to 1800 must have brains that slide in and out of that with great facility.
- My calculating brain part seems like the part I identify with most. It's kind of jumpy, shallow, and comes up with specific answers that virtually never hold up fully to computer analysis. Ok maybe like 55%. It also takes the most effort, and gets bogged down alot.
- My instinct brain part seem to come alive when there is mate or something really, really close to it. It is right alot, but lacks details, so if unchecked it leads to hasty inaccurate moves. Occasionally, it freaks out in the opening, whether or not there is a trap. I figure I will chalk it up to experience if I really am missing something, and go ahead and come up with some move based on what I do see.
- My gut feeling brain part that one move is better than another seems to be right about 75% of the time.
- My visualization brain part... well, I unfortunately do not have a visualization brain part; when I close my eyes the best facsimile of a chess board that I can come up with is maybe the outline of a few squares and pieces.
- Lastly, my memory brain part serves me well over 95% of the time. I solve those mate problems with pattern recognition much more frequently than calculation.
Looking over all of this, it becomes apparent why I and other intermediate players have shifted to a more focused tactical study approach. We need to learn use the best brain parts for the job at hand!

Guide to Magnetism
When you run into problem after problem where the solution is unusual from a beginner's point of view, you develop countermeasures. You can pretty much figure that they are going to put in postions that will first trick you, and then teach you. I determined that my solutions were being arrived at ever so slowly because I calculated all natural responses before examining the weird and suicidal ones. I switched my calculating the other way and viola! Think about it; it's easy to eliminate crazy looking moves, so why not calculate them first?
It's odd, but now that I get mate in 2 correct regularly (Horray!), the magnetic perception has mostly gone away, and when I encounter a decoy or deflection tactic now I simply feel that these moves are forcing.
I feel like I have walked away from this with something more than just checkmate familiarity, although it is difficult to verbalize completely. I would summarize it like this: Attack squares and lines, not (necessarily) pieces.
Sancho and Temposchlucker say that this happened to them when they began shifting their focus from the pieces to the fields they cover.
-=-=-=-=-=-=-
1285, 1286, 1290, 1291, 1294
If your really feeling it, try these slightly harder ones:
1252, 1243, 1229, and a the ever so tricky 1198
On a similar track, I have noticed feeling similar solving line/square clearance problems, although the difference is like you are somehow stealing time:
Line clearance 1230, 1196
Square clearance 1997, 1242, 1200
And finally, one that gave me the feeling of stopping time all together:
Decoy and double checkmate 1211
Remember, Kamikaze attacks first for maximum magnetism. I would be interested if this works for anyone, so feel free leave a comment if you succeed. And if the feeling just is not happening, you might consider sleeping on it and then repeating them 6 more days in a row ;).
A Taste of Tactics
In case somebody out there is thinking about doing DLM's 7 circles using books, I offer up my first group of 40 exercises as a starter. They are from the following books:
- Seirawan's Winning Chess Tactics - great writer and player
- Burgess' The Mammoth Book of Chess - more towards intermediate and advancing players, a helpful reference
- Laszlo Polgar's 5334 Problems, Combinations, and Games - fun, large, and bricklike, containing many, many mate problems
- Problems at the end ("Ben's") of my list are from positions I have gathered. Warning! One of the positions is illegal - I use Winboard to open it; it's from Chessmaster 8000's "Move to Safety" drills which has no Kings. Position 4 and 5 are mistakes I would rather not repeat. Ahem.
It's a fairly easy group, but still a challenge to do all in 20 minutes. The Polgar 5334 list covers every major theme for mate in 2, using the most essential examples I could find. Good Luck!

Well met
"You may learn much more from a game you lose than from a game you win. You will have to lose hundreds of games before becoming a good player" Jose Raul Capablanca
Well, he never saw my wins. ;)
Greetings all. Another Knight Errant in the fold reporting in.
I too was tired of making tactical errors, so I began a modified De La Maza 7 circles approach in December 2004. I have been using books, doing groups of 40 problems 7 times, 4-6 days a week for 30 min. to 2 hours per day. I am not attempting to get rating points as quickly as his program is designed for, but simply have a good regimen of tactics practice and have a life.
I would say that all but 5 of the problems I have used would be in the "10-30" in CT-Art difficulty terms, over half in the "10" range.
In spite of the complaints I have read, I am going to eventually get CT-Art because it's simply much better at covering the themes than I would be, scouring books for a well rounded collection.
So far things look like this:
For problems 81-120 I am now using a speed/accuracy see-saw approach:
Circle 1 - 4 min/problem - Attempt to get first move, best reply, and next move(s)
Circle 2 - Take as long as is needed- Attempt to accurately calculate every variation
Circle 3 - 2 min/problem - Attempt to get first move, best reply, and next move(s)
Circle 4 - Take as long as is needed- Attempt to accurately calculate every variation
Circle 5 - 1 min/problem - Attempt to get first move, best reply, and next move(s)
Circle 6 - Take as long as is needed- Attempt to accurately calculate every variation
Circle 7 - .5 min/problem - Attempt to get first move, best reply, and next move(s)
For what it's worth, in making a version of the plan that uses less time, my feeling was that it's the regularity of the tactical problem solving much more so than the time per day that was important.
Even though my time investment has been a fraction of you all, I have experienced identical frustrations with the whole process, feeling like this is taking something fun and making it a grind. Even worse, my standard games have gotten a little bit worse, especially in messy positions, although on the plus side my blitz rating has improved. I limit my blitz games out of concern over getting bad habits that detract from whatever ability I have to play standard games. I figure the standard drop in performance is temporary.
Anyway, this is my "have a life while your learning tactics" formula.
The other thing worth mentioning is playing vision training games (where both players either write current moves and the chess board is updated regularly to show the position 2 half moves back).
More on mistakes later. Much, much more.
