The results are typically bizarre.

My question is: In normal bridge is it correct to pass the transfer here?

And what does South bid after North passes?

I bid 2H which was doubled and made 2HSX-3 for 800.

Here's what happened at the other table.

It's a somewhat common agreement to have 1nt bidder pass over the double of a transfer bid with only 2 cards, and accept with 3+ cards. This allows say a 2-suited 5-5 responder to choose their other suit to play in.

 

After it gets passed around to you, if you want to sign off at 2M you can either bid the major yourself, or with most agreements, redouble as a "re-transfer" to get partner to bid it. Other bids retain their natural meanings, but one can make distinctions between say direct bids vs re-transfer then another bid. Like 3m without redoubling to retransfer can be to play, while 3m after a redouble could be normal and forcing.

 

As for what GIB will do, how it will interpret things, you'd have to examine the hover tips carefully and hope they are accurate, I don't know if it will interpret rdbl sequences reasonably or not, I wouldn't count on it. Load up deals on a practice table and find out.

It is just a unlucky hand. Partner is minimum for 1NT. Has just 2♥. 6-0 split. West hand auto 2 x X. East auto pass. I would not lose sleep over what happened.

Does the robot system allow you to use Stayman on this hand? Doesn't help this time, but if partner had four Spades it might

No, GIB doesn't play crawling Stayman. 2♣ - 2♦ - 2♥ promises invitational values with 5-4 in the majors.

pass shows 2, bid shows 3card heart so normal is to bid 2hearts now
