The battle of the cues.
I didn't exactly wanted to show the world how I blundered. I gave this example in my previous post in order to investigate how the mechanism of the choice of moves works. I thought this was a clearcut example. But the blunder element turned out to be distractive.
I tend to overfocus somewhat when thinking about something. Such focussing seems to work by means of suppressing the signals that could interrupt. Or by raising the threshold.
Nevertheless, certain signals manage to exceed the threshold and certain do not. This determines which move we chose. Guidance of focus seems to manipulate these signals or thresholds. Whether this guidance is conscious or not. This guidance seems to be driven by habits when its not conscious.
Besides that, those patterns that are stored with strong cues for retrieval seem to produce stronger signals.
Forgetfulnes dampens the signals overtime. Especially those that are acquired on automatic pilot.
I estimate the amount of patterns you need to know to play chess well somewhere between 100 and 400 patterns. This amount is so little that it means that on the highest level of chessplay the difference cannot be made by knowing more patterns. Hence other factors must be decisive.
If you look at a position, some patterns seem to scream "see me!" while others do not. Which patterns manage to scream louder than the threshold are highly personal and depend on the make up of the cues.
Take for instance the following example: we have a few older members of the club who play chess for 40 years or so. One of them is rated about 1500. He gives lessons to the youth. He tells them exactly how to move the pieces in the opening. Develope well etcetera. The strange thing is that when he plays himself, he doesn't obey these rules at all. He has forgotten everything.
Now what kind of cue is that? Which let him retrieve certain knowledge from memory when giving lessons while leaving him on his own when playing. There seem to be a lot of circumstancial factors.
