South has 8 TPs with 8hcp, how to bid at balancing seat on Gib CC?

Here is Gib CC.

1♥ = balancing overcall --- 5+♥,9+TPs.

2♥ = balancing jump overcall --- twice rebiddable ♥,13+TPs.

3♥ = banlancing double jump overcall --- 7+♥,strong rebiddable ♥,17-20 TPs.

4♥ = 24+hcp,strong rebiddable ♥,25 TPs.

What would you take next auction in this hand?

 

1- Pass

It is ok, there is no any thing to occur.

 

2- 1♥

If you really bid 1♥, you will have no any reason to rebid your ♥ suit.

- If don't rebid 3♥

 

Hand-1

- If really rebid 3♥

Hand-2

Now see the explanation on 4♥, how to suddently upgrade to "14+hcp,15-21TPs"? Obviously it is illogic.

 

- If really jump rebid 4♥, disaster will strike.

Hand-4

4♥ says " 24+hcp,strong rebiddable ♥,25+TPs ".

Obviously it is rediculous. West is a opener with 21hcp at most, then for South seat, it is impossible to have 24+hcp.

 

3- 2♥/3♥

This is a true lie, so Gib never do so except human.

 

4- Directly jump 4♥

 

Gib never do so, but human likes to do it. Here Gib partner would have two way to respond.

This hand has 8 HCP. Certainly more TP but I never bother with that for entering the bidding, either with GIB or otherwise. Any bid above 1H is a gross overbid, and pass seems bizarre with an 8 card suit, so make the normal 1H call.

 

Not sure how you set up these hands, seems odd that #2 passed 3H but #3 cuebid on the same auction. Let's see....gross underbid pass, mild overbid 3S, normal action raise to 4H.
