There was a non-GIB-based discussion of this topic in a recent thread: http://www.bridgebas...__1#entry587647

So, what is GIB's system for bidding over quantitative invites? I would have thought that showing the number of aces was "intermediate/advanced standard", but it appears that GIB expects something else. (Of course, we can't read the whole explanation of 5♥.) It seems clear that the description should not be "5- H", since "5- H" means "0-5 H". Does GIB think that 5♥ shows five hearts?

It's one way to play -- to suggest a possible safer place to play when accepting the invitation. But the 5- doesn't seem consistent with that. Perhaps GIB simply doesn't understand and the bid is undefined (the description being gibberish).

5♥-> -- 2-5 ♣; 2-5 ♦; 5- ♥; 2-5 ♠; 20-21 HCP; biddable ♥

Book bid on 5♥ is actually pass - to play with 3-4 cards fit in invitee's hand.

5NT seems like escape plan for misclicks, but are we sure it's misclick?

GIB would proceed with 6NT or Pass after such 4NT invite, so simulation led to 6N here. Supposedly there are just two answers on 4NT.

If 5♣/♦/♥/♠ are additional invites or aces answers you might go down even with all aces in hand.

5NT wasn't really defined, but added just in case when fit seems impossible like in the example if player picked 5♠. GIB would return to 5NT.

Then, should the description include "4-5H" rather than "5-H"?

I think this is bad. Any bid over 4NT should be an acceptance of the slam invite, and should not be passable at the 5-level.
