Playing in a BBO ACBL pairs tourney.

If you ask aces, partner has two. What then?

If you ask kings, partner has two. What then?

My real question is whether it's hopelessly optimistic to bid 7N after hearing about the aces & kings.

My calculus was something along the lines of: (1) 2/3 chance that pd has KD and 7N should then be in the bag except for 4-0 diamonds offside, (2) even if he doesn't have KD there's a good chance 7N comes home with KD onside, (3) even if KD offside maybe partner has long-suit source of tricks. So I guessed it was an 80%-plus grand and bid it.

As you might imagine by my raising the issue, things didn't work out even after partner held 18 points...

So was this a good percentage bid that just didn't work out, or is there a flaw in my logic?

If only we were playing a system that extends beyond gerber...

Set diamonds as trumps and sort it out. If you can't, 7NT.

I'd also bid the grand.

set diamonds, ask keycards, when 1 is missing, partner must have at least ♣AQ so 6NT is cold.

If only...

Didn't specify, but it was a pickup partner ("let's play your card, pd"), did NOT have agreement to use four-way transfers, and 1430 and Gerber were agreements on ace-asks.

I don't play 4 suit transfers, but do play 3♦ one suited and forcing, so 4♥ is keycard after this.

With a pickup I probably punt as you did.
