Feedback for Convention Chart, Part 2
The committee is making a bunch of good liberalizations. Let's not escalate from thankless please.
Feedback for Convention Chart, Part 2
Conventional responses are allowed, but opponents may play defenses that would be disallowed over natural bids.
Feedback for Convention Chart, Part 2
Yes, disallowed opening 15 is problematic. It should be reworded to "without a known 4-card suit". Otherwise it can fairly easily be evaded by including a non-three suiter pattern (643?) and then satisfy constructive definition 18a without infringing disallowed opening 15.
Feedback for Convention Chart, Part 2
Not natural changes permissible defenses (Disallowed overcalls 1&2 no longer apply).
Feedback for Convention Chart, Part 2
It looks like it satisfies 18a and is not otherwise banned so is allowed. It's not "natural" however so opponents can play defenses that would otherwise be banned by disallowed overcalls 1&2.

Andrew, the current definition found on the alert chart is 4+ in a major and 3+ in a minor. ACBL attempted to ban 4 card openers at the two level that could be less than 10 HCP by banning conventions over them before regulators had the authority to ban them ...
Feedback for Convention Chart, Part 2
You're right, but if someone bids something natural and conventional, e.g., 1 natural showing (5+4+) clubs and third seat, we can't play 1 showing 15+ artificial no known suit according to overcalls 1. Can't play 1 asking for a stopper ...
Proposed System Regulations Changes to GCOC
The WBF policy is a little ambiguous: "A pair may prepare written defences against the Brown Sticker elements of any system. Such defences will have to be given to the opponents (two clearly legible copies) at an appropriate time and place prior to the start of that segment, to be ...
Feedback for Convention Chart, Part 2
Tim/Michael, with the definition of direct overcalls, anything goes after the response to an opening bid, even a natural response to a natural opening. But whether an opening bid is defined to be natural or artificial has consequences. Banana custard doesn't seem to.
Feedback for Convention Chart, Part 2
Overcalls 1 has the same problem. If there's a natural call that shows two suits at the one level there's a two-level cue bid of the 2nd suit they showed and possibly a one-level cue bid too. Unless you define "new suit", you've banned the cue bid ...
