So what's with 3D (alerted as denying 4H)?

 

Why not bid 3H (showing 4 hearts i presume and a 3 suited hand, oops, but that would be telling)?

It's also rather questionable why it should rebid 2♣ with only 4-4 in the minors rather than simply passing.

and what's with 1D (alerted as showing an opening bid)?

Good hand and good topic.

 

1- Obviously Gibs don't know how to handle with this situation after 4th suit.

Here there are two best examples.

A- When with 1N interference :

B- When without interference :

Result : 4♥E=

 

2- After 4th suit, here programmers need to improve its bidding rules on Gib CC.

Note 3♥ says " 4+♣,4+♦,4+♥,2-♠,11-16hcp,12-18TPs,forcing to 3N ".

Obviously "4+♥" is impossible, only 4♥.

However Gib has no way to rebid 3♥ showing 4-card ♥, in fact there is no related bidding rule.

It's also rather questionable why it should rebid 2♣ with only 4-4 in the minors rather than simply passing.

Yes.

However if simply passing, unfortunately a ridicuous matter will happen.

Note I only help West Gib to pass after 1N interference at the beginning.

So I think there is no related bidding rule.
