Slam try minor 2-suiters after 2NT opening

[Free]

I'm looking for a good scheme after the following auction:

 

2NT - 3♠*

3NT** - ???

 

* = puppet, to play 3NT or with a GF hand with both minors

** = obligated

 

So basicly, every bid now should show a slam invite hand with both minors, starting with 44+ ♦-♣.

Scheme from forrester's TRS system:

 

2NT 3♠ (puppet to 3NT)

3NT ...

 

4♣ = 5♣ 4♦ slammish. Now opener 4/5NT = misfit min/max, 4♦ = fit, 4M = club fit, cue.

 

4♦ = 4♣ 5♦ slammish. Now opener 4/5NT = misfit min/max, 4♥/♠ = ♣/♦ fit, slammish

 

4♥ = 6♣ slammish. Now opener 4/5NT = misfit, 4♠= good fit

 

4♠ = 6♦ slammish. Now opener 4/5NT = misfit, 5♣= good fit

 

4NT = 55 minors slammish but NF. Now opener 5m = the end, 5♥/♠ = ♣/♦ good hand for 7

 

5♣ = 55 minors slam force. Now opener 5/6NT = bad fit max/min, 5♦ = fit, 5M = club fit, cue.

 

Other sequences:

 

2NT 3NT = BARON (prone to memory lapse, though). This is how you find minor slams with 44 minors. Now if fit is found, it's slam force and next step RKCB. Else 4/5NT bids = misfit min/max.

 

2NT 4♣/♦ = ♥/♠ slam try. Now opener 1st step = good fit, 4/5NT = misfit

 

2NT 4NT = 55 minor not slammish NF, but better usead as quantitative if 2NT has a 3-pt range

I'm looking for a good scheme after the following auction:

 

2NT - 3♠*

3NT** - ???

 

* = puppet, to play 3NT or with a GF hand with both minors

** = obligated

 

So basicly, every bid now should show a slam invite hand with both minors, starting with 44+ ♦-♣.

Here's a common scheme played in my area:

4♣: both; equal length or primary ♣

4♦: both; primary ♦

4♥: single-suited ♣

4♠: single-suited ♦

4NT: (23)44

 

Over 4♣, 4♥ is RKC in clubs. Other bids are natural.

Over 4♦, 4♥ is RKC in ♣, 4♠ is RKC in ♦. 4NT/5♣/5♦ are to play.

Over 4♥/4♠, cheapest step other than 4NT is RKC in partner's minor.

 

 

Here is another possible scheme:

2NT-4♣: both minors; equal or primary ♣

2NT-3♠-3NT-

4♣: both minors, primary ♦

4♦: RKC in ♣

4♥: RKC in ♦

4♠: 2344

4NT: 3244

 

Over 2NT-4♣ or 2NT-3♠-4♣:

4♦ and 4NT are natural.

4♥, 4♠, and 5♣ are RKC responses for clubs.

 

This scheme allows the more unknown/shapely hand to be in control of the auction, which may work better for slam bidding. Note that there is no Gerber in this scheme.

gerber is evil and should never be mentioned in this forum. same thing with flannery

Reg partner and I also play that, after 2NT-3♥-3♠-4♣, 2NT-3♣-3♠-4♦ or any similar auction where a minor is introduced at the four level:

 

Cheapest step is a rejection of partner's suit. This is like a natural 4NT bid. Other responses are as if partner had bid RKC in his suit. Over the rejection, partner can still insist on his suit by bidding the cheapest step as RKC.

 

2NT-3♣-3♠-4♣-4♥ = 0/3 keys, likes clubs

2NT-3♦-3♥-4♦-4♥-4♠-5♦= 2 keys w/o trump Q, doesn't like diamonds

Apollo's scheme is what I use when I am forced to play 2/1 - it's quite similar or identical to the Soloff convention (have not read it in detail, just glanced at it).

 

Let's say it together: Gerber is a baby food manufacturer. I have graduated from peas and carrots...

 

I feel better.

Tnx for the responses, but the singlesuiters are not included in this bid. We use 4 suit transfers (3NT = 6+♣, 4♣ = 6+♦) after which we can cuebid if we have a slam try hand. So there's extra room for a better description of 2-suiters. :P

Any accidents involving 2NT-3NT yet? :P

 

IMO any gain from playing 3NT as forcing is offset by the effort needed to remember the method. Even the best players forget things once in a while.

It seems like one of the weaknesses of the approach Noble (Apollo81) outlined is that keycard responses may not be useful when the minor two-suiter has a void. Given at least 5-5 in the minors, a void is not all that low probability. Since Free doesn't have to deal with one-suited hands, perhaps he could use:

 

4♣/♦ = better minor, no void (bid clubs with equal)

4♥/♠ = void, now opener's 4NT rejects and otherwise respond to "keycard" where the five keycards are AK in each minor and A of the non-void suit.

How about then

 

2NT 3♠

3NT ...

 

4♣ = 54

4♦ = 45

4♥ = 64

4♠ = 46

4NT = 55

5♣ = 55, stronger

Hi everyone

 

I let opener bid 4m with a 4(+) card holding, his 4M show a slam type 4(+) card holding in the ranking minor. If you do not let opener show a 4 card minor, he might not end up playing the hand.

 

2NT-3S-3NT-4C=4C and 5+ Ds

4D=4D and 5+ Cs

4H=1255(0355) numeric bidding

4S=2155(3055)

 

Opener plays the hand in the vast majority of cases.

 

Single suited hands do not use 2NT-3S* as their start in my methods.

 

Regards,

Robert
