Weak Two-Bid Structure

In a Nutshell

I like to play aggressive (but sensible) weak two-bids, often with just a sturdy 5-card suit, but this causes problems when partner is the one with a good hand. Therefore, I devised a rebid structure (after a forcing 2 NT response) to indicate a 5-carder immediately, or to define the opening in three gradients (good, average, or dog) instead of the usual two.

Details

Opening bids of 2 D, 2 H and 2 S are weak two-bids. Range is 5-11 HCP and style is undisciplined but sensible. Good 5 card suits (usually 3 of top 5 cards) are permissible at all vulnerabilities. Decent 5 card suits are permissible at favorable vulnerability.

Standard Defense

This defense is a practical method to counter enemy interference over our forcing bids that elicit specific rebids in the following situations:

1. 2 NT response to weak two-bid or analogous structure after our weak jump overcall, weak jump shift response, or 2 H or 2 S overcall of an enemy 1 NT opening

2. 2 NT response to Michaels cue-bid or Astro 2 C or 2 D

3. Cue-bid response to unusual 2 NT overcall

Rebid structure:

After an enemy bid:
