Good-Bad 2NT and Transfer/Rubens advances

[Michiel]

If you play both Good-Bad 2NT and Rubens advances,
which has the priority when you have a situation
in which both apply.

An example:

Left opponent opens 1Sp, partner bids 2Cl, right opponent
bids 2Di (negative freebid). And now it's your turn, holding:

S: K 9
H: K J 9 8
D: K 9 7 3
C: Q 7 4

Playing transfer advances:
2Sp = Good raise in clubs
2SA = Natural. Stops in spades and diamonds
3Kl = Weak raise in clubs

Playing Good-Bad:
2NT = Good-Bad. You want to compete only at the 3-level
3Cl = Good raise in clubs
2Sp = ... erm, there's another question for you... what should
this show in 4th position after lefty opened, partner followed
en lefty competed on the 2-level?

Hi Michiel,

You get similar systemic question when playing any puppet-like style in some
situations (eg Good/Bad or Lebensohl) and Rubensohl or similar in others.

We did this a lot ten or more years ago, in national and international
competition (I haven't played a great deal since). We had quite a simple
rule of thumb: if you were limited, either by passing at some point or
making a limited bid, then the weak option applied (Good/Bad in your case).
If we were not limited (excluding inferential limitations based on all four
bidders, as the opponents may psyche) then the strong option (Rubensohl in
your case) applied.

Using that rule, above, Rubensohl would apply. If you had previously
passed, Good/Bad would apply.

Regards, Newroad

Hi Newroad,

I don't think this is what Michiel meant. He was talking about when to
apply a Rubens' advance or G/B playing both. I think I remember
explaining to him in the Dutch bridge newsgroup some time ago that you
can play both and the difference is only in the 2NT bid and the 3-level
bids. In competition however you have to decide whether you continue
playing transfer advances or not. I personally don't, since it's a lot
of work coping with all possible interventions by RHO. You have to
account for double and bids from RHO and they are not the same.

However, I found your response useful since I play various -sohl's in my
system. We have been looking for a simple rule of thumb stating in which
situation Rubensohl applies and in what other situations G/B. So,
thanks. :-)

Kind regards,
Micha Keijzers

You are quite right.

I don't doubt the efficacy of the systemic approaches on other hands,
but what's the problem in simply bidding 3 no trump, and taking all the
pressure off partner--with this particular hand. You have 12 prime
points, and what possibly could partner have that wouldn't give you a
play for 3 no trump opposite a two level second hand overcall--however
"light" you may want to be. AJ10 xxxxx and an ace should give you a
reasonable play. and even one club less may be enough. If they a lead
a diamond to the ace (lefty is still favorite to hold the ace of
diamonds) and a spade through, so be it, but with righty short in
spades, partner may have three to the jack, and probably even better.
