I did 1355 problems on George Renko's CD Intensive course tactics 6 times.
Then I started to suffer from what I have called "memodrosis".
After a "rest" of two months I continued with the 7th time. I find out now that of about 40% of the problems it is as if I have never seen them before. Well, I sort of recognize them as "I might have seen this one earlier" but I have no clue at the solution whatsoever.
I think those problems were the ones in the first place that gave me a feeling of suffering from memodrosis. Which is the feeling of memorizing the moves by context in stead of absorbing the underlying pattern.
Maybe the 60% that I do can solve (is this still English?) after 2 months is not bad at all, but it's not what I expected.
So I have to conclude that just playing thru the solution on automatic pilot and with little calculation isn't of much help.
Now I take my time to work thru the problems. I put the 40% difficult ones even on the board.
After I solved a problem I take a few minutes to look at the total pattern of the solution.
Of course this slows things tremendously down. Today it took me 1,5 hour to solve 5 problems. But this is not about making efforts, it is about making progress.
Prof. Elo has the last word in this.
The final test will be the repetition of TCT step 3, 4 and 5 over a few months. These problems were simpler and since I hadn't the feeling of suffering from memodrosis I expect that the results will be better.
Beside this I couldn't resist to do some endgame work any longer.
So I took Papa Polgars endgame brick and put the positions on my board and both on the computerscreen. I play the endgames against the computer (Arena with SOS-engine).
No need to tell I take my time now. . .
For some reason I always have to find out things the hard way.
People like MDLM seem to have some subtle instinct that tell them what is the right way to do things.
I only have my logic, which compares to instinct as brute force to pruning.
I mean, the conclusions I draw after moving for months in the wrong direction are not difficult at all. It took me 3 years to conclude that traning tactics is all important.
After that it took me 2,5 years to find out that repetition plays a keyrole in studying tactics. And now this.
I assume this is the price for having logic as your guide. Because logic is destructive in its nature. It can only tell you what is NOT true, but it lacks the creativity to tell what IS true.
But in the long run even brute force will give good results. . .
And what is important, you will know exactly how you have done it, so you can tell it to others.
And now some more good news.
I reread the articles of DLM and found that his 7 circles should take 127 days and not 168 as I had in my mind. Since 400 points in 400 days means 127 points in 127 days, my entrance in the Hall of Fame has come a little closer. . .
