Patterns in the long term memory behave like animals in the jungle.
Only the fittest will survive.
The human mind is very efficient. It never tries to find the objective best solution but it settles for the first solution that has succes.
A solution just good enough to survive costs less energy than the best solution.
If one is used to play 3. Df3 in a certain variation, that might be enough to become chesschampion of Honduras. So that pattern is stored in memory as "best fit" for the given situation. But when our Hondurassic champion tries this pattern for example in the Corustournament he might well be knocked from the board.
So in international play this pattern of 3. Df3 will not survive.
This continuous competition between patterns in the mind plays an important role.
Here is where emotion comes in.
A pattern "has to know" if it is needed any longer after being used.
Emotion "rewards" the pattern with a good feeling if the result is good. The pattern grows stronger by this reward, and the next time it reports itself earlier.
If the use of a pattern has a bad result, it is "punished" by a bad feeling and becomes weaker.
So in a next simular case it will not report itself immediatly, and another pattern might be "the fittest".
This is the process of forgetting.
Emotions are the power that regulate the adaptation of the mind by burning the patterns in our brains or by forgetting patterns.
During our tactical training emotions are not very strong. (however, if I hear about the struggle of some. . .)
That's why it is neccesary to play a lot next to the training. Especially rated OTB games have a high emotional impact. But even internetgames will do.
So being euphoric after a win and feeling the pit in the stomach after a loss is the best thing that can happen to you. . .
