The Rubensohl convention after a 2♠ overcall on 1NT opening
The Rubensohl is used by the responder after a 1NT opening and an overcall. Zia recommends that experienced players use this convention.
After a natural overcall of 2 PI:
- from 2NT onwards all bids are Texas transfer bids. 2NT is therefore artificial (Texas for clubs)
- the impossible Texas is a Stayman
Le cue-bid at 3 ♠ is a strong Stayman fort with a shortness in ♠
- the double is a takeout. It could be a Stayman with just 8HCP or show a balanced hand of 8HCP or more.
