We have this topic in our Blog:
If you have any questions, comments or you just liked it, feel free to share your thoughts here.
But it fails to answer the main question. With distractions out of the way, what are the causes of loss of concentration? If it was just as simple as keep at it (this isn't just a chess problem either)...
Can I offer:
Wrong difficulty of material
Poor material (e.g. badly explained, alternative reasonable moves not considered)
Boring and/or repetitive
Too often need to work out what is the next thing to do, or need to think about the process rather than do it
Situation novelty vs knowing what to do and being organised to do it already
Over-training (including marathon sessions vs regular)
Too much of one task (including wrong mix of playing vs study)
Insufficient breaks, or relaxation
Not attending to all the other things in life that are nagging you
Poor fitness and diet
Sleep hygiene or other factors tiring oneself (such as a day of work, family, ...)
Long time before any payoff that can make one excited about more training
Plateaus or even dips
Lack of others to share with, or compete against
Why does rating matter so much, particularly in such a short period.
Not too long ago I played a team of 50 somethings that hadn't played since university, and they got back to where there were 2000+ quite quickly. Another example is Nick Arkell who got back to around 2200 in a couple of years after not playing for a long while (though I suppose it helps if your brother is a GM).
This information is really helpful to us keep it up. After reading this article I decided to work with dedication and also concentration with some punishments for my blunders. Like analising the game and if I defete by others in a game i will find my mistake what is that move where I move wrong and also what is the right move.
Coming to the article it is very easy for reading and understanding the meaning of words I like the quotation of sun Tsu which is related to battle. Keep going I am with you.
Thank you brother of my chess mood family
