The last 3 weeks I focussed on repeating old sessions of CTS. I memorized about 1200 positions. If our old theory of 1 problem=1 pattern and 34 patterns=1 ratingpoint is correct, that should lead to an improvement of 35 ratingpoints at CTS. But I noticed no improvement whatsoever. Even a little decline. There are two possible explanations for this. The first is that this is a normal statistical anomaly. I have seen that in the past. But I have never seen that it lasted for 3 weeks.
The other explanation is that the theory isn't correct.
So we might have found extra circumstancial evidence that massive repetition isn't the way to go.
I reworked my system of mates with The Mother Of All Mates (MOAM).
I found 29 MOAM. They are derived from King of the Spills unsurpassed Fundamental Checkmates. If you look at the 29 MOAM I think that everybody would agree why there are exactly 29 and not 28 or 30.
From this I derived 55 variants of MOAM by adding pieces to the positions. This happened on a somewhat subjective base, and possibly I missed a few important ones. I tried to define the positions that the mind sees as unique. Since we don't know how the mind works, this is under investigation.
From the point where we are arrived now I can go in two directions:
I can go in the direction of more diversity. The 55 mates are end positions. There are probably a few hundreds (pre-) positions that lead in a forced way to these 55 end positions. These "pre-positions" are possibly the ones to store in our system.
The other direction is to search for "vision". MDLM had a few vision-drills. If the geometric essentials of the 29 MOAM can be found, maybe sophisticated drills can be developed which would help to let the mates "pop up".
If I look in the direction of more diversity, I can see no end. So I start with research on "vision".
