2NT Stayman Relay

[Vampyr]

FWIW, here is how I show minor suit interest (combined with a version of Puppet Stayman):

 

2NT-3S demands bid of 3NT, after which 4♣ and 4♦ are two-suited minor slam tries, 4♥ and 4♠ single-suited.

 

2NT-3NT is Baron; 4-card suits are bid up the line.

 

A minor suit can be shown after first bidding Stayman to show interest in the majors (we don't play that after 2NT-3♣, 3♦ showing 1+ 4-card major, 4♣ and 4♦ by responder show both majors.)

 

It comes up infrequently enough that we have never felt the need to do anything more complex.

2NT - ?

3C = stayman, promising 4cd major

3D/3H transfers, accept with all hands except super accepts, next other major is SI

3S = both minors, at least mild slam try

4C/4D = natural slam try

 

2NT - 3C

3D = no 4 card major

3H = 4 hearts no 4 spades

3S = 4 spades

3NT = both 4card majors (then 4C is puppet to 4D for natural slam try and 4D/4H are transfers either to play or to bid rkcb later)

 

2NT - 3C

3D - 3H/3S = smolen; with strong 5-5 bid 3H and if partner doesnt bid 3S then bid 4C/4D as slam tries with 5-5 majors or 4H with signoff; jumps to 5C are 5-4-4-0.

 

new major is slam try after both stayman and transfer; new minor is natural slam try after which 4NT is negative and other bids are cuebids (or kickbacks if you fancy to play this).

 

2NT - 3NT is natural and to play (of course, any system which doesn't contain this is weak imo) as 2NT - 3C - 3D/H/S - 3NT.

 

This is imo the best system after strong 2NT and it's also quite simple.

IF you want to be able to bid all 2 suiters and all 5-4-4-0's you could add that 4H/4S bids are 5-4-4-0 with major void and 5-4 minors but I don't think it will ever come up.

It doesn't work. The system may look pretty but they will have too many chances to double your 3♠ (or make interference from lack of this double) on normal deals when you want to play 3NT. Additional accuracy achieved from freeing 3NT bid for other uses will never make up for this.

Maybe, but we have this auction a lot, and I can't remember when they last doubled our 3♠ bid or made (an inference?) from the lack of a double. Of course this may be because we have usually bid Kokish by the time we have reached that point, and the opponents are reluctant to ask about the 6th bid (and the 5th alerted bid) in an auction where the only action they can be contemplating is a lead-directing double. If this is so there is a problem, but I do not know what to do about it.

Well, if you're Kokishing the same player has already bid an artificial 2♠, so you don't lose much by giving your opponent a chance to recover from forgetting to double that :)
