This may sound biased, but you should look at SAYC. As for improving, I would recommend the following reading material: -Barbra Seagram "25 Bridge Conventions You Should Know" (and other books in the series...) -William S. Root "How to Play a Bridge Hand", "How to Defend a Bridge Hand" -The various bridge websites, like bridgevaria.com, bridgeclues.com, and bridgeguys.com I myself am a junior intermediate player, so rest assured that this stuff is good.
