Looks like the robot was trying to set the contract and unblocking.

Firstly, it is not unjust, because if you had made exactly the same plays, you would have gotten the same result.

Secondly, it is a good play by GIB (and indeed by declarer), not illogical.

If GIB throws the Q, declarer makes 10 tricks (by playing a heart).
If GIB throws a , declarer makes 10 tricks (by playing diamonds).
If GIB throws the A, declarer makes:

- 9 tricks if east has the heart king
- 10 tricks if east has the heart ten not but king
- 11 tricks otherwise.

Assuming all 10 layouts of the remaining 5 hearts are equally likely, that's 40% for 9 tricks, 30% for 10 tricks, 30% for 11 tricks - thus a better play.
