This convention is used by a large number of players worldwide.It's a type of Texas bid by the Responder when the Opp has overcalled with 1
♦ or 1
♥. The aim is for the Overcaller to be on lead...
After an overcall, Responder can bid the following :
- X always promises a minimum of 4 cards in the major immediately after the overcalled suit :
- On an 1♦ overcall X promises a minimum of 4♥ cards
- On a 1♥ overcall X promises a minimum of 4♠ cards
- bidding 1♥ promises a minimum of 4 ♠ cards
- bidding 1♠ denies 4 ♠ cards but gives the possibility of a 1NT bid
The X from Responder promises at least 4 cards in the suit ranked one level higher than that of Overcaller's suit. In this instance it's COs.
