Defence to Multi
Does anyone have experience, please, of the following defence to a Multi 2 , so as to be able to offer worthwhile opinions on a sequence which has given rise to a possible ruling? (Assume that the Multi in question is the fairly common version with a weak two in either major, a strong balanced hand of defined range or a strong three-suiter).
Double shows diamonds
A 2 overcall is for takeout (whatever that means)
Pass can be strong
After a delayed double (apparently showing a better hand than a 2 overcall), Lebensohl is NOT played.
The system card doesn't mention a 2NT overcall, but the players say that it would be about 15-17 with excellent stops in both majors (apparently AJx is borderline).
