Chess Training Tips-Kotov Method

Chess Training Tips-Kotov Method
Set up a position and study it. Don't move the pieces but set yourself a time limit to solve the position in.
One of the things you can do if you really want to improve is use the "Russian/Kotov Method". This is an exercise that is guaranteed to make you better, but one that I have difficulty getting even Masters to do.
Set up a position (a problem from a book, perhaps) and study it. Set yourself a time limit in which to solve the position; you decide how much, though the more time the better. Now begin - but don't move the pieces as you try to figure it out.
Use a chess clock to time yourself and
write down your answers beforeyou look at the book for the answer.
Do this Exercise on a Regular Basis
Sound easy? Yeah sure, that's what everyone says, but few do this one thing as a planned, regular basis and it is probably the single greatest exercise any serious player can use to improve their game.
Every top Russian GM has used this method at one time or the other; shouldn't it be part of your regular training regime?
