After an opening of e 1 ♣ or 1 ♦, the responder jumps in the other minor
This convention is now widely used and Kit recommends you should use it.
After, a minor opening and the opps have passed, with :
- 5 or 6 cards in the opening minor
- 8 to 11HCPs
- No 4 cards major
- bid a jump in the other minor
This support is more constructive than a preempt in the opening minor.
Careful ! to use it, you must have passed first.
