Yes, unfortunately, the cardplay engine is buggy, too.
Quite similar examples, were reported here some weeks ago.

I guess Gib playing server is too old to do the work so well.

This isn't an age problem. A human beginner or a young program almost certainly wouldn't make that mistake and if it did it would be quickly fixed.
This is big problem. I saw Gib with Qxx if trump offside play the Q on first round of trump.
There is a major bug in card play.

And then we have these masterpiece defenses...

Not sure if the first-lead is a different algorithm than subsequent cards, but buggy it is.

...unless I missed a BBO announcement, that any of these have now been fixed, of course.

BBO is aware of this hand, and investigating. Thanks
Please let me know about any questions or interest or bug reports about GIB.

Can the bot be taught to count top tricks?

It knows how to count top tricks. My home copy of GIB just claims at trick 1.

Why it went haywire here, they'll have to investigate.

Once thing GIB seemingly does perfectly is accept or reject claims. I would not mind if BBO's GIB would claim when it has all remaining tricks certain.

We've moved on from hundreds of threads never being replied to, to your replies saying they're being looked into. Yet I haven't seen a single response with the result of said investigation.

Was anything found? Or did they give up? Bugs like the ones in this thread seem seem to be the highest priority given how common they are.

I think GIB needs a major overhaul in its card play program.

These absurd plays or bids occur when bots run out of memory. I don't know the technicalities but it's something about servers and memory, not about how robots are programmed. Happens only to challenge and daylong robots, you won;t get these when renting basic robots or in robot tournaments.

This statement is untrue about the rented bots.
I gave examples for the bot that I rented for 1$, an advanced robot which refused to take the defeating trick vs their slam in 2 different hands in 1 week.
Yes they make much less mistakes than regular bots but they still have issues.

Sorry I didn't mean to say rented bots have no bugs.
