Everyone vul. GIB held the following hand as North.


T
432
K985
K8763

I was dealer as South and the bidding went.

1=1N=3=3

The description for the 3 bid was 3 ; 11-12 total points; forcing

This has to be some kind of bug, right?

I believe most people playing 2/1 use 4 to show the 3-card limit raise and 3[spades ]is preference. Because Gib plays constructive raises preference could include 3-card support.
Is possible Gib has switched meanings because it uses constructive raises.
Sarcasm is a state of mind

That's fine but the fact remains that GIB preferred spades with a singleton over diamonds holding four card support. The fact that it announced that it had three spades when it only had one is incidental but might shed light on what's wrong.

Looks like a clearcut bug to me, I can replicate it on a bidding table too. Not sure why GIB wouldn't bid 4, as its hand matches that description perfectly.
