Partner opens then passes 1-2-3 times over GIB’s repeated Spade bids on
7HCP, a Jack-high 6-card trump suit, and a singleton in the suit opened by
partner then bid twice by GIB’s RHO.

Maybe I was a wimp with my passes. Nevertheless, if GIB's coninued overruling
with the weaker hand was the result of simulation rather than a bug I would like
to suggest turning off the simulator after the second pass when partner opens and
then passes twice.

I also notice my GIB was the only one of 22 which failed to make 9 tricks.

I wonder how that happened, but not enough to plow through the other table
results bid by bid and trick by trick looking for some nuance I might not be
able to recognize.

You have to have at least 3 ♠ to pass 1♠, so it competes up to the 3 level based on the LAW.

You have to lose 1♣ 2♦ 1♥ 1♠. Although if West fails to switch to a ♦ after the ♣A has been knocked out, a ♦ can be pitched.

Unfortunately, the travelers are no longer on myhands, so I can't see what happened at the other tables now. They undoubtedly had different auctions; you passed a forcing bid, when even in a best hand format partner could have enough for game. This must have caused the robots to defend differently.

Thank you for replying.

I do not understand the 3-card holding requirement for a pass.

Is there a LAW site where I can the details?

Other tables auction and play-by play were availble to me at my tournament results page.

3♣ could have been making but I think it goes down 1 because provided you duck the first finesse in clubs because GIB can only get into dummy twice but 3 ♣ could have been making so you should have raised to 2♠ or bid 1NT then hopefully you wouldn't have had a competitive auction and not got to 3♠.

North's 1♠ bid only promises a 4-card suit. If you're willing to play in the suit, you must have support, otherwise you would have bid something else.

I misclicked earlier, can I get an Undo?

Most of the auctions were 1♣ 1♠ 1NT 2♠. There were also a couple of 1♣ 1♠ 1NT 2♠ 3♠ 4♠ and a couple of 1♣ 1♠ 1NT 2♠ 4♠. With a different auction, you get different defenses. And there was one guy who opened 1NT instead of 1♣, so 3♠ was played from the South instead of North.

At all the other tables, West continued ♥ when it won the club. I it may have been trying to set up for a ♥ ruff. And in the case of the 1NT opener, it probably expected South to have ♦J, so switching to a ♦ won't gain anything (the robots assume you won't misguess).

Your auction probably really confused the robot. You passed a forcing bid, which made it impossible for it to deal out sample hands consistent with the auction. So your robots defended differently than all the rest.

Ah- OK that makes sense.

Undo acceptable this time. The rest sounds reasonable.
