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.
- 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
2 spades which shows five spades and a hand limited to 7HCP maximum
