Escape Sequence after they double our 11-14 nt
With a very weak 4333 it's getting a little tricky. You could Rdbl en Rdbl 2 again if it's doubled, or you could transfer to hearts
All Rdbl's in any sequence are for escape except the obliged Rdbl after a 1nt x pas.
If opener bids an impossible suit, it is to play and real... or a psych in shortness to redouble aftwerwards.
With a 3 suiter you als Rdbl and bid your short suit and redouble it if they double.... no double no trouble
Besides the Twisted Swine complex, anything is allowed and psychs on nothing are the best way to go. Its better to go down 7 undoubled in a 2-1 fit with 12 point together.
