Today, we are introducing GIBBO, the next evolution of GIB (Ginsberg’s Intelligent Bridgeplayer), bringing a noticeably stronger and more natural robot experience to your games.

This major update, powered by neural network technology, marks a significant leap forward in the development of BBO’s most popular bridge robot, GIB.

To mark the occasion, we are officially rebranding GIB as GIBBO. The new name reflects both the scale of this upgrade and the new technology behind it.

Read the full announcement here.

Feedback, comments, bug reports are always welcome in the BBO Robot Forum (please mention which game you were playing, when posting a hand).

GIB Upgrades Thread available with all GIB upgrades going back a few (many!) years. Changelog for V44 is posted here.

I was pleased to read this and the full announcement, despite thinking there was a bit of mystification about Basic Robot (it was hardly difficult to reverse the suppressions of simulation made to differentiate the two robots in the first place). Also, using a neural network to replace double dummy may well be equally effective, but I don't see how it improves the user experience. If the cost reduction is significant then I hope prices for Advanced robot will drop, or at least cease to rise astronomically.

I played a tournament with an Advanced GiB 2/1 today and failed to spot evident differences: did I jump the gun or was I just inattentive?
It made one discussable bid that cost a bottom (failing to open QT9 AJ83 AT32 84 in 4th seat unlike the rest of the field) and one unfixed system error (opening 1NT with a 5 card major and then missing the 5-3 fit despite Stayman) that cost another bottom.
I don't remember any evident improved leads or plays, but I wasn't actively checking.

Curious to hear the first experiences of others.

Any chance we can have Old GIB vs new GIB to compare them?

I haven't noticed any difference yet either, not sure if it's been implemented yet or in phases?

The name during play is still the same, if that is any clue.


It would be a step forwards if clicking on the name brought up a profile, as for a human player.

it's fully rolled out. any robot you play with is the new one

We tested GIBBO vs GIB V43 over tens of throusands of deals and each time GIBBO was vastly superior. Below is an example from a set of 4 matches of 4,000 deals between GIBBO and GIB V43:

Basic GIBBO vs. Basic GIB 43 - Matchpoints: GIBBO wins with 57.25%
Basic GIBBO vs. Basic GIB 43 - IMPs: GIBBO wins +3633 IMPs (+0.9 IMPs / board)
Advanced GIBBO vs. Advanced GIB 43 - Matchpoints: GIBBO wins with 53.86%
Advanced GIBBO vs. Advanced GIB 43 - IMPs: GIBBO wins +1594 IMPs (+0.4 IMPs / board)

"Vastly superior" seems a stretch based on these numbers.
