Robot does not have to bid 2H. In fact, there is no reason to bid at all.

Hi Goffster
Welcome you to Gib robot forum. I would answer your question, but I think your point is wrong.
- Now first let's see your hand .

---

- You said Robot doesn't have to bid 2♥, in fact, there is no reason to bid at all.
Ok, I would check and replay your hand to tell its exact reason.

1- It normally goes :

---

2- If north pass, south must regard it as cooperative penalty double.

---

Result : 1♠Exx= 520


Obviously, there is a very serious consequence.
Any ideas? I can try to help you.

Since the XX shows 3cd ♠-support, South knows North is marked with 2 or fewer spades.
Even my dog can tell you, North's Pass is not for penalties.

Only an idiot would take North's Pass to be for penalties.

Very good reply.

I always remember that Stephen Tu had ever said " Gib is a kind of rigid...", that's to say Gib is a kind of loyalty model which determines Gibs' bidding are different from human.
Now I can take a real example.
Here is from 2016 USBC QF - Segment 7 of 8

So human isn't a kind of rigid model, there are many differences between Gibs and human.

I would consider bidding 2♥ to be a silly bid. If doubler has 5 clubs and 4 hearts, clubs will probably play much better. You don't have a strong preference so why bid a 3 card suit that may bypass your best suit? No guarantees, but I would have bid 1NT since I've got diamonds very well stopped and scattered values.

"Cooperative penalty double"?????? Only in the GIB world where there is a hole in the bidding charts.

As the song says,

What is it good for?

Absolutely nothing.

LOL
Oh, my god, how could I forget the brackets on Cooperative?
Now you see I am typing it as ( Cooperative ) penalty double, I think I have " fixed " this hole in the bidding charts.

Welcome you to point out my mistakes, and share with everyone.

It would tell you a story how world experts dealt with such similar hand, it is different from Gibs.

As I early said , Gib CC is
- bid 2♥= escape, weakish bid.
- pass, Gib will regard it as " agree with penalty option." This is a Gib approach, it differ with human CC !

North's best escape is 1NT.
