I quickly worked out that the North robot was unlikely to have many Hearts.
Normally in this sequence bidding 3NT over a minor opening in a best hand tournament lands one in a fairly safe game contract.
But not today.
What does the North robot have?
What would you bid?

I'd expect him to have what he had although more often with the 10 being the A and the A being smaller. I'm bidding something other than 5 no idea how GIB would interpret 5 but to a human I would expect it to show a heart control and no diamond control (so presumably a club control of some sort) and to know whether I want to play in spades or clubs assuming 5-6.

Since the robot would expect you to double with 4, he would only bid this way with 56 in the blacks. This hand is probably worth a 5 cue, as you have the fillers in his suit.

If you don't play MAFIA then I read North as being 56 in the blacks South has denied 4 by failing to X 1.

5/ should be makeable with slam as an outside chance.

I pass 4 or bid 4NT (2 keycards) if taking a risk.

A 5 response shows the control I'm looking for denying AK, with the requisite keycards/Q for the slam try. 6 follows
