Why do players like myself constantly make excuses to justify that our time that we've set out to do for our chess training seems to take a back seat?
Chess, like it or not, is as much a game of memory and as well as a test of how your brain's cognitive abilities.
In order to improve our chess skills, we need to build small little memory building blocks of certain tactics/endgames (psychologists refer to this as "chunking") and from there, we memorise (internalise) these combinations and ideas and commit them to long-term memory.
Basic techniques like deflection, skewers, blockade, forks etc. needs to be remembered and used effectively if we are to get better at chess.
And the problem is that as we move up the rating chain, it requires more and more effort on our part to make a smaller gain. We need more time to learn and grasp new ideas, concepts and the unfortunate thing is that not many of us can be like Bobby Fischer, who can simply pick up a book and remember everything.
And this is what makes chess improvement so hard to do for adult working players. We have so precious limited time to invest in this sport.
Chess is indeed an easy game to learn but a hard one to master.
