Weak jump shifts in majors after 1m opening are very in vogue, and spreading like a rash in our local clubs. Most seem to be playing them as (1m) P (2M) = 6+ M and 0-5 points Although others play 2-5 points, or sometimes a little stronger. I usually feel cheated in 4th seat. We probably have balance of points, but partner maybe weak or have balanced hand if they are silent over 1m. Obviously 4th hand can X for takeout, but are there more sophisticated methods on the market that you can share with me? Looking forward to receiving your advice.
