1NT opening not always wonderful

[Zelandakh]

Thx again, Zel.... I only wish I had thought of that !

 

BTW, what do you use the 3D! "bonus bid" as ?

 

I use it as both majors, at least 5-5 with slam interest. This is in addition to 1NT - 4C which also shows both majors 5-5 and the auction 1NT - 2C (puppet) - 2D - 3C (GF 4+ hearts, 4+ spades), so no shortage of ways to bid this hand type!

Because of what twofor posted, I would think 5D was already a grand last train. Opener does not need to be asked twice. Responder asked for kings, knowing opener doesn't have any and knowing his partner knows this is the case.

 

First, I am not entirely sure that the analysis is correct for all people. AKx-xx-Axx-AQxxx seems too strong for me to open 1NT. However, some do.

 

Second, I was proposing an auction. If you want to be complete in the analysis, then 5♦ probably should be a Queen-ask contextually, not a King ask and not Grand Last Train. Using that assumption:

 

1NT-2♦

2♥-3♣

4♣(power raise, two top clubs, deferring)-4♦(RKCB)

answer-5♦(Queen ask)

5♠(queen)-5NT(grand last train)

 

Something like this is a start.

 

Third, though, all sorts of possible sequences are possible. The idea of "no two last trains" seems wrong. The first "last train" may be looking for heart help but the second "last train" looking for "other help." It depends on agreements.

I usually open 1C with this hand.

1C 1H

2S(good hand, 6+C) 3C(fit, gf)

3N 4D(RKC)

blabla.

 

If you open 1NT, it may go like this:

1N 2D

2H 2N(gf, waiting, using 2S for invitational hands)

3C(5+C) 4C

4D(RKC) 4N

5D 6H(HKQJ)

7C/7NT

Bidding this grand is a piece of cake if you start with 1♣, but what about 1NT opening?
