Sometimes it will be 3 / 4. Or 4 / 3 in our touching suits , if we have to run, we have to run.

Well, I'm not sure what it gets you over either Guoba rescues (non-Canadians may know it as Moscow escapes, but they're wrong) or a rescue system with an immediate strength-showing XX.

Any pass-forces-redouble has two downsides:

• 4th seat gets two shots at it (although this one, where the strength showing nature is obvious round 1, probably has a different best meanings for each round than Guoba). This one, the doubler also gets a chance to reconsider, like the strength-showing XX, but also can continue to pass the decision to partner.
  
• You can't play 1NTx. Many experts have laughed at me for caring, as 1NTxx is game, but the number of huge matchpoint results I have got from -100 into partscores or -200 or -300 into game is at least memorable (and +180 is almost never worth any fewer matchpoints than +760 would have been). -200 into partscores, not so much. -400 or -600 into game? Also, not so much.

For a system that prioritises finding the least bad place to go down, this one seems very sensible. It's not my priority, as regular readers here will well know.
