I've never been super aggressive about opening light but will do so on occasion. Our old notes required a floor of 10 HCP, based on the ACBL Basic Chart which allows natural one-level openings with at least 10 HCP or a hand that meets the Rule of 19. That chart is now used only for games with a MP limit of 300. The Basic+ Chart (up to 3,000 MPs) allows natural one-level openings of 8 HCP or a hand that meets the Rule of 17.
I'm not sure I want to open that light but I'd be interested in any insights regarding the actual effectiveness of light openings in third seat. You should assume declarer skills common to ordinary club players (not Bob Hamman). We played two-way reverse Drury, if that's relevant, though I'd be open to persuasion on that.
I'm sure jillybean will suggest that I use the Rule of 16 and 24 for this decision, but I'd be interested in other views as well.
