I failed in this hand,no problem,Gib still is a good player,after all.
Look at the explanations of both 3♣ and 4♣.
3♣ says " 5+♣,21-hcp,16-22TPs".
4♣ says " 4-♦,3-♥,21-hcp,twice rebiddable ♣,18-22TPs".
Now let's understand Gib better together,The blame is useless.
1-Should my 3♣ be a playable bidding?
If you think my 3♣ is incorrectly,what's your option?
I think almost of 3♣ should be 6-card long suit,5-card suit is rare.If really 5-card ♣,after Gib N cuebid 2♣,I would make double.
2- Should rebid-3♣ show 16+TPs at least?
3- 3♦ is no problem,but its explanations is worth discussing, should it be forcing a round?
In a word, the root causes of the error come from the explanations of 3♣,right?
