For my hand,my 3♥ is reasonable in Gib CC,but after 3♠,I only bid 5♦ without stopper in ♥.
After Gib N cuebid 5♥,I bid 6♦ again,it shows weakness again,strangely Gib N don't signoff,and bid up to 7♦,whose fault?
If it is my fault,how to bid for me?

Yours and GIB's system. With a human, you could expect 5♦ to be interpreted the way you meant it. With GIB, it showed extra strength, which you didn't have.

After 3♠,it is not forcing if I rebid 4♦ with less than 17-18TP,I think it will lose games in many hands with 13-16TP.

You're right, and there are several threads about not being able to play 5m, only 4 or 6.

No blame, it's not easy to reach 7NT on these cards

It's a bit unfortunate trump are 3-0, but it does make more sense to start drawing trupms with the ♦A from south, since east is slightly more likely to have a void in diamonds.

I think you are playing results too much Lycier. On the prior thread you want to be in slam with the DK onside. (you are right that 2S was an underbid). But on this hand, you don't want to be in the nearly 90% (with no opposing bidding) grand slam? And with the opposing bidding it is nearly 100%. If you went down it was declarer error.

He's right but Gibs 7♦ is ridiculous. a small slam is usually sufficient for a good board. to bid a grand Gib should have solid evidence.
