Gib may forget its GCC?

According to Gib CC,I don't think it is right to open strong 2♣ with 26hcp in the balanced hand,it should open 3NT directly with 26hcp.ok?

I don't think Gib treats 5422 hands as balanced. I think it should, and this is a greater failing than whether to open 2C or (ugh) 3N

Anther question, why doesn't Gib make cuebid in support of ♥? It has mobster hand for ♥. Gib seems to cuebid and sign-off when it should cuebid or KC.

Exactly what bid are you suggesting by which GIB?

[georgi]

3NT opening could have only 5m332 or 4m/M(432/333) shape. GIB won't open having 5422 of any kind, including 5M or 2M2M 45 in minors.

 

Also about cuebidding, new suit by opener would be natural. 3♠/4♦ would be just 5♣+4♠(or other suit) and not confirmation for fit in hearts.

 

In theory is still possible opener having 5m4M and responder has 4M4M.

[Bbradley62]

(a)So, do we think that both East and West bid properly to end up in this 4♥ contract?

(b)Out of curiosity, in response to a 3N opening, what does 4♣ mean?

[Stephen Tu]

I think it's gross for 3♥ to only show 4+ H. IMO 3♥ should be 5+H any strength (I think it's too awkward to have to bid 3♦ with 4- total pts), and 3♦ should just deny 5 cd major and leave room for opener to bid 4 cd major if have one.

 

Also in general I think GIB needs to be more flexible about opening in NT and rebidding in NT, it should be allowed on 5m(422) patterns, and 6m(322) patterns. 3♣ should have 6+ clubs or singleton somewhere IMO, especially since it bids horribly after 3♣ rebids, continuations are much better defined after NT rebids.

(b)Out of curiosity, in response to a 3N opening, what does 4♣ mean?

 

After 3NT opening GIB plays:

 

4♣ - Gerber

4♦/4♥ - Major transfer.

4♠ not defined

4NT - Quantitative 6-7HCP.

5♣/5♦ - 6+ cards naturally, 4-6TP.
