The Rubensohl after a 1NT opening and a 2 diamond overcall
The Rubensohl is used by the responder after a 1NT opening and an overcall. Zia recommends that experienced players use this system.
After a natural overcall of 2 diamonds:
After a natural overcall of 2 diamonds:
- - all the responder's bids in a suit at the two level are natural
- - from 2NT onwards all bids are Texas transfer bids. 2NT is therefore artificial (Texas for clubs)
- - the impossible Texas is a Stayman
- - the double is a takeout. It could be a Stayman with just 8HCP or show a balanced hand of 8HCP or more.

double This multi-purpose double takes the place of the Stayman.
After a natural overcall of 2 diamonds
- The responder's bids
- in a suit at the two level are natural and non forcing. They are limited to a maximum of 7HCP.
- The double is not punitive. It requires at least 7-8HCP and often reveals a hand that would have bid 2NT without the overcall. The double asks the Partner to bid a four or five-card suit or to bid NT if he has stoppers in the overcall suit. With a suitable hand, the opener can also pass and transform the double into a punitive one! With a hand of just 8HCP it can also be used by the responder as a Stayman non game forcing.

The Texas responses
From 2NT onwards all the responses are Texas. The impossible Texas (for the overcall suit) is a Stayman. This forcing bid requires 8HCP and at least one four-card major.
From 2NT onwards all the responses are Texas. The impossible Texas (for the overcall suit) is a Stayman. This forcing bid requires 8HCP and at least one four-card major.
- 1NT - 2 diamonds - 2NT = Texas for clubs (it guarantees 6 cards)
- 11NT - 2 diamonds - 3 clubs = the impossible Texas. The responder cannot want to play 3 diamonds so it's a game-forcing Stayman.
- 11NT - 2 diamonds - 3 diamonds = Texas for hearts
- 11NT - 2 diamonds - 3 hearts = Texas for spades
- 11NT - 2 diamonds - 4 diamonds = a major two-suiter at least 5-5 1NT - 2 diamonds - double = either a weak Stayman, or else a regular hand of 8-9HCP
