I'm still uneasy about
1) not having the redouble alert partner that he can double advancer's runout
2) responder bidding out with a 4/4 ahead of opener. Opener might have a 5-cd suit that would manage opposite a doubleton.
Partner argues that 2-suited hands are very common and that it makes more sense catering to this than trying to catch the opponents.
What do other people think?
Perhaps you can cater to problem #1 by inverting pass and redouble. Then pass alerts Opener that they can double any advance or they redouble if 3rd seat passes. As others have said the disadvantage is not being able to play 1NTX as well as giving 3rd seat 2 ways of running. Most pairs include other hand types into this forcing pass too but there is no need to do so when you want a call available that unequivocally shows strength.
Bidding 4-4s with a very weak hand is not a problem since you are very likely to find some kind of fit opposite unless you open alot of offshape 1NTs. Opener can still show a 5+ card suit by bidding something other than the pass or correct response too. Remember though that Opener has no guarantee of finding even a doubleton opposite. One last thing - if you do play a scheme like this then you need to think a little bit about how you want to deal with weak 4333 hands. The main options are to treat the hand as 1-suited, to upgrade a 3 card suit to 4, or to use one or more artificial redoubles. The last of these is arguably the best option but the second is probably more common.

If he prefers clubs he bids 2C. You pass that with juust clubs or both, bid 2D with just diamonds. If Opener prefers diamonds he redoubles, and you bid accordingly. This way you do not bypass clubs to show diamond preference.
You could also make 2C one or both majors and even redouble as one or both red suits if you wanted, along the same lines, as another idea.

1NT-(DBL pen)-?
Pass: Opener will mostly RDBL, but not always (That is making it more difficult for LHO with a weak distributional hand. He is not sure that 1NTX will not be passed)
RDBL: C or 5cH&4cS or D&H
2C: D or 5cS&4cH
2D: H
2H: S
2S: C (invitational)
2NT: D (invitational)
3C: distributional minors & weak
3D: distributional or GF majors
3H/3S: preemptive
1NT-(DBL)-Pass-(Pass)
RDBL-(Pass)-?
Pass: 9+
2C: C+other
2D: D+S
2H: H+S, no preference
1NT-(Pass)-Pass-(DBL)
Pass-(Pass)-?
RDBL: 5c minor
2C: C+ other
2D: D + M
2H: majors
What if opponents run after a forcing pass situation?
- If they run and responder showed strength, DBL is penalty
- If they run and responder didnt showed strength, DBL is negative.
- If responder bids at the 3-level this remains RUBENSOHL if he has a non-limited hand.
If he has a limited hand, he bids naturally (2NT for both minors)
(i.e. 1NT (PASS) PASS (DBL))

I don't understand Pass and redouble possibly with the same intent; so, even though two-suiters might be rare in responder's hand we can still use the space available for when they do come up.
Also, your 2N Rubensohl is certain to be much less needed ---since it encompasses hands which would be content to play in 1NTX.

No doubt being able to show a 5/5 is nice, but responder might still guess well. If responder wants to compete, he'll bid the higher ranking suit. If he wants to run, he'll name the lower ranking suit...and then run to the higher ranking if it's doubled.
I would only use Rubensohl for 6-cd suits. They may take more tricks at the 3 level than partner can take in 1N. Plus, bidding these immediately clarifies the meaning of rdbl and then subsequent introduction of suit.
Welcoming of further criticism or agreement. Learned a lot already. Thanks.

I've been playing weak NT all my life and I definitely think you should run with 4-4 if the hand is weak enough that 1NT is unlikely to make. If they double your 14-16 the situation is not that different. With a hand such as xx Qxxx JTxx xxx I would hate to be playing a method where my choices are putting down dummy in 1NTX or guessing which red suit. I really doubt there is a strong majority for playing 1NTx when responder is 4-4 and weak.

Do you really open 5422 1NT often enough to make this a sensible agreement?

I play weak NT and have no formal runouts with any partners; it is surprising how often 4th hand rescues you. Anyway, are you suggesting something along the lines of rdbl forces 4-card suits up the line?

1. Responder shouldn't run with a 4432 before opener has a chance to show a 5-cd suit.
2. Next hand may rescue if responder passes.
3. Next hand will rescue more often if responder's pass is not forcing.
4. Neither 5/5s nor 8+ hcps are likely in responder's hand. If redouble is assigned to mean either one of these, it will be infrequent.
5. It seems important that redouble have a meaning by opener.
I don't think 5422s are frequent. I can see the value of running when opener has a 5-cd suit or is 4432 and weak or concentrated. How about...
1N dbl
P-no 5-cd suit, nf
.....P- a maximum or 4333
.....rdbl-wants to run, a 4432
.....other- suit
rdbl-transfer to clubs, possibly other meanings
2C-transfer to diamonds

If redouble is used as described in your last post, or as you originally posted, do not disclose it as a transfer.
If one of the meanings might not include having a club suit, describe it as a relay showing clubs or (X) or (Y).

Would you explain what you mean? In this latest, opener is only running when minimum or concentrated with two place to play. We might be out of the frying pan and into the fire, but we're only running when we're in a bad spot and have chances to get out of it.

Point taken. Kgr had a nice contribution with some other possible meanings, but as these auctions are infrequent, I want to reduce memory load. Plus, if opener always knows that responder has a specific suit, he can sometimes compete.
In general I like the transfer idea. it has occurred to me that it gives the opponents extra tempos to do evil things.

P-nothing to say, not forcing
.....rdbl-weak and 4432
.....suit-5cd suit
rdbl-weak, 5-cd minor or 5/5 majors
2C-stayman, could be 3-suit takeout of clubs or weak 5/4 in the majors, could be invitational hands including 4M/5m, Smolensk, etc
2D-transfer
2H-transfer
2S-size ask (not likely used against penalty doubles)
2N-GF puppet stayman
3m-invitational
So obviously 2S and 2N could be better assigned. However, this is less memory drain.
I'm more concerned with how responder should bid with an invitational hand and a four or five card major. Passing sounds right, but if opener gets in the way?
Also concerned with opener's rebids after a pass.

Pass forces redouble, either to play or scramble a fit
XX forces 2♣, with either a minor or both majors
other bids are standard, so Stayman, transfers, etc.
This was the first method I ever came up with, long before I found out it was a standard run-out system. It is ok for low memory load although not as effective in practise as the Helvic family imho. My favourite of these is modified Spelvic, probably more complicated than you would want but:
After 1NT - (X)
===============
Pass forces redouble, either to play or various other possibilities (see below)
XX forces 2♣ and shows a 1-suited hand
2♣ shows clubs and spades*
2♦ shows diamonds and spades
2♥ shows hearts and spades with equal/better spades
2♠ is natural and willing to be raised to 3 if Opener has a suitable hand
2NT is both minors, at least 5-5
3 of a suit is preemptive
After Pass and XX
=================
2♣ shows clubs and a red suit*
2♦ shows diamonds and hearts
2♥ shows hearts and spades with better hearts
(optional)
2♠ shows a GF hand with spades and another (freak)
2NT shows a GF hand with both minors (freak)
3♣ shows a GF hand with clubs and hearts (freak)
3♦ shows a GF hand with diamonds and hearts (freak)
After XX and 2♣
===============
Pass shows clubs*
2♦ shows diamonds
2♥ shows hearts
2♠ shows spades and unwilling for partner to raise to 3
(optional)
2NT shows a GF hand with spades (freak)
3♣ shows a GF hand with clubs (freak)
3♦ shows a GF hand with diamonds (freak)
3♥ shows a GF hand with hearts (freak)
* to cope with 4333 hands you bid as if you had 1 club more than is in your hand, then if 2♣ gets doubled a redouble shows this. Therefore all bids of 2♣ by Responder can be made with one club less than advertised.
In other words, immediate bids show spades, Redouble shows a 1-suited hand, and pass is everything else. I genuinely believe this is the best run-out method available, even without the ability to stop in 1NTX.

Over a penalty double of 1N:
Pass asks opener to XX, can be to play or scrambling
XX is a single-suited minor suit hand or majors, 6-4 invitational+(never happens), relays to 2C
Systems on (with the exception that we have slightly different rules for garbage stayman)
Opener has the option of bidding a 5 card minor suit instead of XXing.
This also fits our style of bidding, as we practically never open 1N with a 5 card major, so if opener has a 5 card suit, its always relatively cheap to bid.
