I don't think this bidding is correct. After the jump to 4NT -- regardless of what it means or promises in the partnership -- the bidders are just groping around.

After the 4NT bid, which, it seems to me, both partners thought did NOT promise spade support, I think the auction went well.

My reasoning here goes something like this -- the 5H bid wasn't a suit, so it must have been conventional; it wasn't DEPO, so it was probably DOPI -- meaning that East thought he had two key cards, presumably implying that the partnership doesn't treat 4NT as keycard.

Six clubs was setting the contract.

I assume that six spades was offering a choice of contracts, given East's amazing club support. And the seven spade bid over seven diamonds was a reasonable choice, although 7NT is better.

I once picked up x, AKQJTxxxxx, x, x. In first seat, I opened 4C, which partner and I understood to be Gerber. He replied 4H (one ace) and I left him there. (We were college students and the grown-ups were not happy with us.) He understood that there was only one thing I cared to know about his hand: the number of aces.

Jumping to 4NT implies that the only thing West cares about is how many aces East has (and maybe kings, if he follows up with 5NT). If there's more conversation worth having, West can/should start with a forcing club bid. If 4NT says West only cares about aces, I'd take 6C as a sign-off showing something similar to my hand above (with long clubs).

Hi,

#1 5H - how many KCs depends on agreement, common is to play DOPI, i.e. 5H would show 2KCs.
#2 6C - since 4NT set trumps for most, 6C is showing a first round control in clubs, a grand slam try.
This is not 100% clear, you have Pass, 5NT av., so it is certainly sensible to play as some kind of
suggestion to play 6C
#3 7S is ok, ..., depends wht you read into 6S.

With kind regards
Marlowe

PS: I prefer 2C instead of ... cant think of an alternative ..., does one really want tto play 6C without
AK in spades, or without the major suit Aces?
With kind regards
