1. Openings: Learn a little about all the openings, and a great deal about the ones you choose to include in your opening repertoire. Why? It gives a club player the best chance of avoiding opening difficulties without endless hours of book study.
2. Balance study and playing time: Why? A club player will need both in order to improve.
3. Always have a strong player critique one's completed tournament games: Why? It will help a club player improve faster by avoiding making the same mistakes over and over.
