I think Gibs have no ability to handle with two long suites since it is a sort of complex hands.
Hand-1
7♥ says " 1+♥,33+TPs ".
However it is impossible in the most situations.
Hand-2
There is no way to show opener's second suit on Gib CC, it often forces opener to return its opening suit so as to describe correctly. See this example hand.
Hand-3
6♥ says " 1+♥,29+TPs ".
However it is impossible in the most situations.
Hand-4
5♣ says " Strong rebiddable ♣,20+TPs ".
20+TPs? Does it really need 20+TPs when overcalling at 5 level?
