Poor defense

by East in this deal trick 3 and trick 10

By bidding 4♥, GIB counts this as preemptive jump. Not game values.

 

So after you showed ♥K,♦K,♣AQJ you showed almost double than expected.

 

That's why West was seeded with ♠QJ and East ducked considering you are either void or singleton.

 

Probably strange from human point of view, but entire layout was twisted for EW and mostly East.

That doesn't explain playing Q♥ at trick 3, has no upside. partner might have QK double (rare) in which youll crash honors

 

or opponent may play your partner for QJ and go for a drop, playin Q gives situation away

There's also no upside to playing low at Trick 10. Declarer is known to have exactly one non-trump; either it's ♠Q (no matter how unlikely) in which case East must rise A, or it's not, in which case it doesn't matter what East does.

 

The problem here is that GIB doesn't figure overall probabilities, he deals a few random hands and those frame his ability to determine likelihoods. It would be nice if GIB could be told that when his play "doesn't matter", he should win the trick if he can and play low otherwise. Of course, that wouldn't be a gross simplification for a reasonable human player, but it would be a clear improvement for GIB.
