The repetition of the opening suit after a 2/1 suit change by the responder
The repetition of the opening suit after a 2/1 suit change by the responder may be the only way to keep the bidding at a low level. Let's not forget that the 2/1 response is auto-forcing.
- The repetition of the opening suit by the opener is merely a 'waiting bid' showing a 1st zone hand (12-14H)
- The jump repetition of the opening suit by the opener shows a strong 6 cards suit and a 2nd zone hand.(15-17H)
