Here is a great handout by Larry Cohen on the best conventions to play. Larry says that playing more conventions than this is counterproductive for 99% of players. He also says, “My observation is that at every level of the game, players are using too many conventions. Too often I see players (from beginner to world champion) misusing or forgetting their methods.”
If you use this handout on your computer, every underlined blue link will lead you to Cohen’s excellent explanation of that convention. I have also added this to the Lesson Handouts page.
Thanks to Clay McCaskey for sending this excellent article to me.
