Defence vs 11-14 NT and weaker
The basic Idea is: They cant do their escape sequence with weak hands after 1NT pass !! If partner doubles, they can't play autoredouble because the tempo has shifted to opener (the wrong hand to start the sequence)
If you have a 5332 you have to option to bid it like a 6 card or as a 2 suiter. It alll depends on the 3 card quality. With bad quality treat is like a 6 card, with a good 3 card treat it like a 2 suiter.
