Hi all

I appreciate many of us like to be somewhat flexible with quantitative NT bids. This hand feels like it needs 34, this one feels like a 32

This one intrigued me since GiB (despite being a bot with precise bid descriptors) asked on the basis of 1 point less than the 12 specified

Nobody's complaining except those who didn't open 2NT



I am curious is this the result of a sim saying. We can get away with 32 this time. Only 2 Aces out. No problem

With 32 combined HCP, it is rare for the missing 8 points to be precisely two aces, and if they aren't both in the opening leader's hand, they may not cash one or both. I have made a grand slam off two cashable aces after a Blackwood misunderstanding. Opening leader didn't have either, and lead another suit, allowing me to take thirteen tricks.

This isn't based on a sim. Basic non-simming GIB will invite with every single balanced 11 or 12 count. The human descriptions of its bids are totally independent from the logic used to make them - while they roughly match in most cases, there are a number of cases where they don't.

As a side point, in almost every case, the possible hands that GIB may hold can't be described solely in terms of HCP / total points / suit lengths, which is all that human descriptions can state. That's why a lot of the time, you need to figure out the underlying logic behind why GIB made a bid, rather than learn what it means based on what the description showed.

Of course, in this case, the description being wrong is just a bug (or GIB making the bid is a bug, take your pick), but it is consistent in what it does.
