Escape mechanism for one no-trump doubled

I haven't come across this in any of my textbooks; I'm sure I didn't make it up so if anyone can give me a reference or a proper name, I would be very grateful. Why not email me; no one else does. I call it Colditz.

Colditz is for use by the partner of the one no-trump bid which has been doubled. There is no corresponding escape for the partner of the doubler.

The theory is that we must develop a way of being able to bid a four-card suit without it being misunderstood or interpreted as a five-card suit. In order to achieve this we are obliged to modify our way of showing a five-card suit. Our hope is that while we are wriggling our way out of this predicament, the opponents will enter the auction and win the contract---to our great pleasure.

Our new way of bidding a five-card suit is to redouble the 1NT*. Partner then bids two clubs which is simply a relay for us to bid our five-card suit. If our suit is clubs, we pass the relay. If the opponents come in, we back out gracefully.

If we now have this novel way of getting to our five-card suit, we can now bid our four-card suit(s). We do this in ascending order (bidding the one we come to first) and settle for the first 4-3 fit we find.

You may think that this is a terrible palaver for what appears to be a comparatively innocuous situation. I can assure you that it isn't. The hazard of the weak no-trump being doubled is the reason why high-stake rubber bridge players usually employ a strong no-trump. You won't lose a lot of money in your one-penny-a hundred rubber bridge game, but you can easily give away several hundred points above the line which is damaging to your reputation, if nothing else.
