Concentrate. Keep your attention on the board. Don’t let your mind wander and don’t you wander either. Don’t leave the board unless necessary.
Use your time to think of specifics and to find the best move. Use your opponent’s time to think in generalities and of future possibilities. Always make sure you use your opponent’s time productively.
Play to win in as few moves as necessary. Don’t waste time gobbling up your opponent’s pawns when you’re well ahead. Go for the safest and most efficient mate.
Until you reach at least master level, playing as error-free as possible is MUCH more effective and important than playing brilliantly, and will win a lot more games for you. One critical error will usually cost you more than a dozen brilliant moves will gain for you. Remember, the first step to mastery, is the elimination of errors.
To improve your chess game, combine STUDY AND PLAY; study and play, study and play, study and play…
Always play “touch-move” and never take back a move. It is against the rules of chess and is detrimental to your improvement.
Avoid having a favorite piece.
Learn chess notation, then record and review your games.
Review all your games. This is how you learn to find & eradicate the mistakes from your play.
Play stronger players frequently, and learn from them. After a loss, ask them to go over the game and point out your mistakes. Playing stronger players strengthens your chess.
Focus on playing your best, rather than on winning. The wins will follow.
Enjoy your wins and learn from your losses. Learn at least one lesson from each loss. You will learn more from one loss than a dozen wins. Defeats are the greatest teachers.
After losing a game, especially against a much stronger player, ask them to review the game with you and show you where you went wrong.
Always play touch-move, and call it if your opponent touches a piece. Do not hold a piece in your hand while thinking.
Focus on the game in front of you, not the one next to you. Good concentration is one of the keys to success in chess.
