New to chess? Here are some quick tips to improve your game. Control the center of the board with your pawns and knights early in the game. Develop your pieces — move knights and bishops out before moving the same piece twice. Castle early to protect your king. Always look for checks, captures and threats before making your move. Practice against the easier AI levels before moving up to harder difficulties.
