Maybe given how fast GIB plays, playing hands at lightning speed well under a minute, we should give it a break when it occasionally gets sloppy.
I gave this hand to my home GIB set to "par mode", long thinking time/large sample analysis, and it plays it perfectly to make. Same with some other declarer play hands posted in this forum recently. I think generally GIB plays quite well as declarer (not well as defender because of signalling ineptitude), when given plenty of time to think. The question is do we really want the BBO GIBs to take 60-90 seconds on the first couple tricks (it gets faster deeper into the hand where the number of possibilities drop fast and it has already analyzed possibilities), or will humans get frustrated waiting for it to play. Also how much computer time per GIB process given the hundreds of people playing robots simultaneously does BBO server farm have to spare?
The download client at least has control for thinking time, but tourneys you are at the mercy of the online server defaults.
Personally, I'd rather get through a lot of hands fast, and have my partner robo-declarer occasionally throw a hand, than sit twiddling my thumbs waiting. If I wanted to wait that long, I'd go play live bridge.
All irrelevant, it is a lousy contract requiring nice break in spades 2/2 or K/Q singleton onside- any 3 card set of spade onside or KQx offside are death combinations and all finesses to work but order of cards to play is irrelevant (except play spades as soon as possible to avoid being ruffed against) (North always ruffs at some point in all side suits). Whether West might hold K10 is irrelevant as East gives it away by playing the QS (Defence of the contract we don't care about and anyway he'd have to play 10S otherwise).
All GIB declarer has to do to make the contract is not assume/simulate is the unlikely singleton A
♥ offside and singleton K
♦ offside and any play other than A
♠ and low one (there is no combination of EW hands where any other play is right- a smoother play running the J
♠ doesn't work if West has KQ8 of
♠ since West just covers the J
♠ and declarer loses two spades.
All Souths who opened 1H deserve the result they got, its a crummy 1H and when your partner is poor at declarer play and opponents poor at defence- you want the best chance to play the hand and 1NT with transfers gives that.
