I believe that the best style is a universal one, tactical and positional at the same time.
Chess is a miniature version of life.
I think that is the difference between the very good and the best.
Chess can help a child develop logical thinking, decision making, reasoning, and pattern recognition skills, which in turn can help math and verbal skills.
There are no take-backs—just as in life. You must think before you move.
I don't like politics especially in chess. All I want is promote chess 24/7.
