1nt-2c-2nt with both majors in SEF Advantages/Disadv.? Further Bidding?
#1
Posted 2009-June-29, 01:58
What advantages does the convention have opposite to answering 2♥ with both majors and reverting to ♠, if necessary? I´m especially interested how the further bidding works, e.g.
- confirming a fit. My partner for example bidded 3♣ to confirm a ♥-fit; I guess, 3♦ would show the ♠-fit. Is this the common treatment in SEF? Is it showing some range of hcp, like inv+? What would other bids after 2nt mean?
- differentiating the route to game or slam with inviting, gf or gf+-hands with one fit in a major. I´m really clueless there.
- gf hands with no 4card major, but good minor(s), with slight slam interest. Maybe those hands wouldn´t be bid via stayman anyway; just asking in case they would.
I hope I am posting in the correct forum. Anyway, thank you in advance for any help.

For your questions: Obviously no more garbage stayman. But this is no big deal opposite a strong NT.
The given information is a huge point. You inform your opponents (bad) and partner (good). To me this did hurt more then it gains, this is why I stopped to play it.
2 step transfers are common after such a 2 NT response. The direct bid of a major suit shows slam interesst and here the systems works best: You can ask the limited dummy and declarers hand is concealed.
The transfers are invitational+ , so 3 club shows 4 hearts and 8-14 HCPs.
I am not sure what the French standard is regarding slam with a minor, but it is certanly not via stayman.

1NT-2♣
2♥-2NT
and it doesn't matter whether responder has a four-card spades or not.
The same is true if responder's second bid is 3m.
It frees
1NT-2NT
for other purposes while at the same time
1NT-2♣
2♥-2♠
can show an invitational hand with 5+ spades (admitted, you can't bid 1NT-2♣-2♦-2♠ with a weak hand with 5♠4♥), so you can also free 1NT-2♥-2♠-2NT/3♠ for other purposes.
Agree with Roland that the disadvantages are bigger than the advantages.

Hi Ron,
I pass and avoid the 4-2 fit after 2 Diamond opposite a typical 3325 hand.
And when I have a slam going hand, the bidding will be at 3 heart and I know that opener/dummy has 44(32) and 15-17 HCPS.
Try to have so much knowledge after any normal strong NT opener.
So, maybe now you can see at least one advantage of this system.
The advantages (some better games, nice slam bidding, freeing 1 NT 2 ♣ 2 ♥ 2 ♠) are there.
But the disadvantages are higher for most players.

We played it, and it did work ok, we did not feel, that we were missing
a lot not playing garbage stayman.
The adv. noone has mentioned yet is, that playing 2C as inv.+, you
can handle intervention after your Stayman bid easier, since you
are basically in a forcing pass situation.
All in all I dont think, that you need to play weak stayman, if you play
strong NT, that does not mean, you have to play the french version
The amount of add. infomation leaked to the opponents is not that huge,
basically the only case this happens is, if declarer is 4-4 in the majors.
We did play Australian Stayman / Extended Stayman, which goes even
further than the version mentioned in the original pot.
We switched to Crawling stayman, as we switched to weak NT, which
occurred 2-3 weeks ago.
With kind regards

May you explain this comment?
Do you think that the world like 2 NT to show both majors and disagree with my view that this is inferior?
Do you think that FES players are not part of your world?
Or do you think that the world like just to state their opinion instead of trying to explain what they think?
Or do you think that the world is too stupid too see that there are pros and cons in many approachs to the game and that a black/white thinking does not help to find the best way?
I guess you think something totally different, but I really would like to know what you think.

And that is a wrong assumption.
Because you may violate partnership agreements, and even if you get a good score on this board due to this action, the damage you may cause to partners
trust is not worth it.

We used to, and we did not feel, that it did hurt.
For us Stayman did promise at least inv. values,
and if did not have inv. values, we could not use
stayman.
We switched, but this is due to the fact, that we
switched to a weak NT, and now it makes sense
to drop the req. of inv. strength for stayman.
The whole discussion overlooks one point:
4441 hands are rare, if I recall it the frequency is 1
or 3% at best, now there are 4 possible orderings,
i.e. we are currently speaking about hands which show
up less than 1% of the time.
And this excludes the analysis, that we also need to req.
hands with less than ? HCPö.
Now you may focus to work on your system so that
you improve your bidding on hands which come up
less than 1% of the time, but I have more urgent things
to clean up.
All in all the whole subject we are currently discussing is
highly overrated.

Playing Stayman (even including garbage) I have often wondered whether you would be better off using rebids higher than 2S, particularly to distinguish min v max openers. Sure you can get a level too high (or I should say an extra level too high) if opener is max and responder has the garbage hand, and you may get doubled when you might have bought it in 2 undoubled. But you gain by playing at the 2 level when opener would decline an invite, and you are also ahead of the game in slam investigation. Certainly if you absolutely guarantee a game try with the 2C response (per P Marlowe) then it would be absurd not to make use of all of the available rebids up to 3N.
Bottom line is I don't think that there is a lot in it, provided that you make maximum use of all of the available bids once you commit to a rebid structure that extends beyond 2S. Just playing 2N to show 4-4 in the majors does not strike me as making maximum use.

I have no strong feelings about garbage stayman. When I played it, the ups and downs seem to level out and Jack summarized well, why.
Maybe a search in a database can find out whether garbage stayman is a long time winner.

Another (small) benefit of bidding 2NT with both majors is that it allows to locate a spade fit more easily in slam auctions (which otherwise would probably start 1NT 2♣ 2♥ 3 or 4NT
Over 2NT most player play 3♣ and 4♣ as transfers for H and 3♦ and 4♦ as transfers for spades. Playing 3♥ and 3♠ as natural SI(instead of natural GI) makes sense but a downside is that the 3 level xfers are no longer SI .
to address the information leak issue some pairs play that 1NT 3♦ shows 4M333 , 3♥ 4spades, 3♠ 4♥ without slam ambitions

Hi Ron,

Over 2♦ I bid 2♥ to show 4-4 or 4-5 & play the 7-card major fit

For me, Garbage Stayman is a proven long-term winner (32 years is long term ). We play a partscore in our best fit instead of playing 1NT with no chance of making it.

By the way, the variation of Garbage Stayman isn´t as well known in other countries as well, maybe. Once, I had 2 garbage stayman sequences in 5 boards, and the American opponents asked me to alert it afterwards. Besides, only about 2 other players bidded stayman according to the score sheet. Sure not representative, but...
