GIBBO messes up despite having a full count

West GIB has full knowledge that his heart card is worthless. West also knows, nearly 100% certainty, that South has the ♠K. At trick 9, when South cashes the ♦K, even a novice human in the West seat would discard a heart.

Not our favourite bot, though. Our hero west chucks a spade! Absurd! Absurd!! Absurd!!!


PS: Worth linking this example from a few weeks ago where the bot messed up a 2-card ending (https://www.bridgeba...ard-ending-how/)

i want to look into this.
it will help me if you share the movie of the entire deal (like you did for the linked 2-card ending)

Will do tomorrow.

The deal is from a Daylong that ends late tonight.

This was Board #4 from the Free Acol Daylong Tournament dated 9th August.

I led the ♦K at trick 10, and West threw a spade while retaining the useless heart. I can't see any logic for this action.

Acol tournaments use another robot.
I have forwarded the issue.

This happened again. In an Acol Daylong tournament.

The West bot had a complete count, but it retained a useless card even as it discarded from the useful long suit. Will share the link tomorrow after tournament ends.

The discard of ♠10 at trick 11, when West held an obviously worthless ♥9, is a joke.

For reference: Board 7, Acol Daylong 01 Sep 2026.
