Systems after 2NT-3R

[Poky]

After 2nt-3M-3nt i play 4M as forcing with the major and suit below and 4M-1 as a retransfer. that makes opener play it when you're long and weak and keeps the bidding open when you're strong. i play 2 under slam tries rather than texas though.

 

There are laydown slams and thin slams. Since thin slams are more frequent and valuable, you need more room to bid the proper ones.

 

Knowing that, how can be better to have:

2NT 4m

as a general slam-try

 

instead of

2NT 3R

and superaccept available with such hands, trying to gain one whole level for exploration purposes?

 

Furthermore, if you bid, as you say:

2NT 3R

with hands containing 6M, being just a bit below a genuine slam-try, does that make your sequence:

 

2NT 3R

3M 4M

?

 

forcing, when opener holds the hidden superaccept with 4 trumps?

 

Say:

♠Axxx ♥AQx ♦AQJx ♣Kx

♠Kxxxxx ♥xxx ♦x ♣Axx
