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♥

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.
