(1♥) 1NT (Pass) 2♦?

Is it any different at higher levels

(2♥) 2NT (Pass) 3♦?

I am also interested if you have some non-standard treatment.

Wayne,

The first issue you have to deal with is whether the suit could be "a poor 4 carder" as in some versions of Symmetric or Blue club which would mena that you might want to lay in that suit.

Assuming that is not the case, the next issue is whether sytemically your NT overcall promised a stopper. Assuming that it does - you do not need a checkback.

I use a treatment from BW which expects that in the case of a 5+M shown we do NOT wish to play in their suit.
Hence, sacrificing Puppet Stayman,

a) lowest C is transfer to Other Major (which allows at least one superaccept below the OM, 2 in the case where it is S) implying 5+OM

B ) lowest D is Stayman - implying likely 4OM

c) H is transfer to C (note that we have 2 superaccepts available to clarify relative quality of superaccept ie 2 top hons etc)

d) S is transfer to D (see above).

If their suit shown is a minor, simple transfers (D &H) to both H & S, om natural nf, S= forcing in om and m= Stayman.

regards,

fred

For lack of having thought of anything better, I play it as "Gameforce - with no other good bid available."

Can't remember having bid it.

[gnasher]

I have played it as:
- Just a transfer (because I often play against 4-card majors).
- Invitational with five of the other major, so that you can stop in 2M.
- 3-suited with shortage in their suit.
- 4 of the other major with a 5-card minor

None of them come up much.

You have five bids here but only four denominations available at the next level:

Diamonds transfer to hearts

Hearts transfer to spades

Other minor natural (but other minor could be diamonds which is a transfer above)

Spades forcing in other minor

minor Stayman (but minor could be diamonds which is a transfer above)

This is non standard but easy to remember:
We play 4 suit transfers and a transfer to opps suit is stayman.

[FrancesHinden]

I don't think it's standard, but we keep things fairly simple, and play the same system as over an opening 1NT or 2NT, but a transfer to their suit is either

i) length in their suit (if the transferer subsequently passes, or raises it to game)
or
ii) 3-suiter, singleton or void in their suit (if the transferer subsequently does something else)

I play 3♣ diamond transfer and transfer to cue stayman.

[kenrexford]

Stopper asking. Presumably a 2NT or better raise without a stopper. Overcaller is expected to bid 2NT(min) or 3NT(max) with a double stop, complete the transfer (2♥) with a single (or worse) stop minimum, and "super-acept" with a single-stop maximum (natural 2♠, 3♣, 3♦, or punty 3♥).

Same treatment for "Smolen" and other calls tat would usually "show" Opener's suit.

Guess I'm the only one who plays it as natural NF in auction 1

I play (1♥)-1NT-(p)-2[CL/♦/♠ as natural stop to put the opener on lead.

As someone who does too, I would be interested in how you play

(1♠) - 1NT - (pass) - 2♥

Apologies for absence of clarity: where the opened suit is a minor, order of priority is

1) maintain standard transfers to both Majors as available (ie D to H, H to S)

2) effectively then C becomes Staymanic

3) lowest S is transfer to unopened minor

Again - quick posting without checking.

THat is just my preference these days.

I think that "standard" is usually just "system on" over a standard (as opposed to Raptor/Polish etc) NT overcall. Whereas that may have some advantages in simplicity, it is clearly less than efficient use of space.

I particularly like the ability to super accept below the M and then, potentially retransfer whenit is S; and similarly the ability to differentiate between the most likely to run holdings (where 6 card minors are likely) and those which won't...

I play 1H P P 1NT P 2H as natural NF, as I do 1H P 1S 1NT P 2H.

I agree with this treatment. This is also where you have a long minor, are invitational or better, don't see your way to 5 of your minor yet, are short in the opponent's suit, not sure if partner can withstand the onslaught of the suit (because of your shortness) from both sides of the table to establish the necessary tricks and therefore probably need an extra stopper from partner.
If partner denies an extra stop and you revert to your minor, partner looking at a maximum (or quick tricks) with excellent values in your minor, can probably shoot to 3NT himself. However, I am unsure of the “super-accept” if it will propel the auction to the 4-level without good values in my suit. Partner can probably make his next move after I have revealed my intentions.

If you play System On after a NT overcall from partner, this bid is free for the above treatment. Note that you can also transfer to your minor, but then the decision is with you. On the lighter mode, why take the blame if you can transfer it to your partner?

This treatment is really useful where partner overcalled 1NT in the pass-out or 4th seat where a stopper is not required.

Hi Wayne,

As we local club members trying to find sources seems traditionally system on. Asking for a heart stopper. But I personally suppose it may vary.

1♥  1nt  p  2♦ ALERT!

If you have hearts stopped, you bid 2NT. If not, you complete the transfer by bidding 2 and your partner can sign off in a safe 2, 3 or 3 without being afraid that he is missing a makeable 3NT.

Sorry I have no idea what happens when auction level increased, such bridge books & articles etc not reached here yet and sometimes it is really hard to find updated web pages, mostly off-beat, stale and depends different SUBJECTIVE trends.

When system off
All bids are natural except a cue bid of the opponent's opening bid, which is Stayman, showing a 4-card major.

(1♠) - 1NT - (pass) - 2♥

I'm interested to hear this also

I like every bid as a transfer, transfer in opps suit is stayman. It's a simple agreement and gives you some oportunities.

So after 1♥-1NT-pass-?:
2♣ = 5+♦
2♦ = stayman
2♥ = 5+♠
2♠ = (5)6+♣

Same as after 2♥-2NT-pass-?.

After the stayman transfer, without 4 card Major you can differentiate between accepting the transfer and bidding 2NT for example.

The biggest drawback is when opps bid ♠, since you're bidding too high...
