no....to improve chess skills work on chess skills
Mind Games and Chess

before i go to a tournament, i like to solve a sudoku puzzle. when your mind's groggy yeah it helps. but chess is chess.

OK , so I will focus my training only on chess, but I will try the hint from easylimbo to warm up my brain with a simple mind game as sudoku puzzle before playing a tough chess game!
I play a lot of poker, backgammon, checkers and arimaa. I find playing these games prepares your mind because I believe you can over do it in one game and find it harder to concentrate later when you need too.
Checkers and arimaa are especially good compliments to chess.
If I want to improve my chess skills, is that helpful to train with other mind games as checkers, reverso, Go, Backgammon or maybe Sudoku ? And if answer is Yes, what are the mind games whose practice will help the improvement in chess.
Thank you for your feedback about this matter and Happy New Year!
