How to raise 1 NT?

[Richard V]

As someone already told, in GIB Stayman is not promising a 4 card major and has to be used for an inviting raise.

 

The complete system is described here:

Bidding after 1NT Opening

[pescetom]

I am beginning to think that while bidding is a critical part of what makes Bridge interesting, it is also its Achilles heel. For my part, I never thought that glancing at the opponents' bidding card before a session was sufficient to capture what they are doing, especially if they have some unusual features in their bidding. Having a photographic memory would be helpful, but I don't have one. If you have to ask one apponent what his partner's bid means all the time the it damages the flow of the bidding, besides which it affords the opponents an unintended means of communication. The ACBL has outlawed some conventions (such as the strong pass/weak 1S system), presumably because they are too disruptive. BIL (and others) outlaws psychics. Having a system that is designed to disrupt the opponents' communication is allowed as long as it isn't TOO disruptive. Kind of like NASCAR allowing innovation but not TOO much innovation... Anyway, playing with the robots has rubbed my nose in this aspect of Bridge which I don't seem to like very much.

 

Bidding and the right of opponents to know your agreements are the cornerstones of bridge, otherwise revert to whist (which was also fun, admittedly).

Asking an opponent what his bid means does NOT afford an unintended means of communication in a well designed electronic system.

GIB plays minor suit stayman, a type of 4 suit transfers, and 2nt may or may not have a 4 card major. Not that uncommon.

Perhaps REAL bridge means something like LONDON bridge which opens as and when needed.

 

Terrific gag.

However it should probably be Tower Bridge, not London Bridge...

As you should probably know, the BBO system card is based on the ACBL convention card. This barely covers opening bids, and a few responses, and a few initial defensive bids. Once you get into the 2nd round of bidding you are usually on your own unless rebidding after a conventional response. I have never been able to find the section where if you bid game on your own (not opening preempt) you show something like 25-40 points.

I don't see what that has to do with anything.

The simple answer, Jschatzman, is that if you want to play with and against the robots, you have to learn the 2/1 bidding system. That is what they play. I don't know how long you have been playing but 2/1 has been the most popular system in the USA for players above the beginner/intermediate level for decades.

 

To answer your first question, to invite to 3NT you must start with 2C Stayman, then bid 2NT the next round.

Obviously not. B-)
