Hello! My partner and I play a simple Standard American system. In the following bid sequence, opener would typically have bid 2NT over responders 2D since a rebid of spades promises 6+ cards in the suit, and the 2NT would be the lowest possible bid over the new suit of responder (which is forcing).

In the bid description, I see that robot only promises 5+ cards when rebidding a suit. What would a 2NT response by robot opener mean in its system rather than a 2 spade rebit? Thank you and best regards.

Last I checked a couple of years ago, GIB never rebids 2nt with any hand. Most definitely not for any logical reason, of course.

Checked again and confirmed that 2NT simply does not exist for GIB.

While that's atrocious, 2 not promising 6 is a common bidding style in general - players are divided into two camps, one where it promises 6, and one where it doesn't.

The logic for those who it doesn't is that if you're forced to bid 3 with a dead minimum 5314 12 count (or 5-5 shapes which could be even weaker openers) as well as stronger hands, how will partner with, say, a 16 count be able to distinguish when you should be in 3NT and when you should be in slam with no room left to explore?
