HI,

#2 4C over 3NT seems clear cut, most likely you will reach 7C or 7NT.

#1 If you dont bid 3NT, your options are 2H or 2NT, over both responder
will bid 3H, and you will find 7H or 7NT.

With kind regards
Marlowe

PS:

1H - 2C
2NT (1) - 3H
3S (2) - 4NT (3)
5H (4) - 5NT (5)
6H (6) - 7H (7)

(1) 15-17, bal
(2) Cue, showing a top honor
(3) RKCB
(4) 4 or 1KC
(5) specific king ask
or 7H - opener showed a 5332 hand, you are home,
if the doubleton is in spades or in clubs, and
with 3 cards in clubs, sometimes the Queen is coming
down.
(6) denies king of clubs and the king of diamonds, due to
the 2C bid a 5C response is possible
(7) since p denied a minor suit king, the chances for holding
the Queen ar not bad, and see 5

so all in all you are not 100% sure of making 13 tricks, but
natural methods will give you the impression, that 7 should be
on

This hand is a walking argument for strong ♣--once opener bids 1♣,responder knows immediately that a grand is likely and has a ridiculous amount of space to find the right fit.

1. Is this grand biddable in either standard or 2/1 GF, and if so, how?

2. Is this grand biddable in either standard or 2/1 GF starting with 1H-2C-3NT (18-19), and if so, how?

Did you even read the OP?

I don't really like 1♥-2♣-3NT. Let's assume that this shows 15-17 balanced, as seems to be the standard treatment. Do you really think the west hand is a 17-count? You have a lot of controls (7 by my count, very high for a 15-17 notrump). Even the club queen is working because that's partner's first bid suit. This hand looks more like 18-19 to me under the circumstances, and I'd bid 2NT which should make the subsequent sequence easier.

Elianna and I would probably bid something like:

1♥ - 2♣
2NT(1) - 3♥
3♠(2) - 4NT(3)
5♣(4) - 6♣(5)
7♥(6) - 7NT(7)

(1) Natural and extras; 15+
(2) Cuebid
(3) 1430 keycard
(4) Really has to be 4 keycards
(5) Asking about the club queen
(6) Club queen
(7) Counts 13 tricks, no reason to risk a bad break

Yes. Have you never answered a question with a statement that a different method is superior on the hand in question?

Playing 2/1, there is no such a bid that shows 18-19 hcp by jumping to 3 NT. In fact, there is no limit bid whatsoever after 2/1 auctions, and mostly no need either. Especially if u are using serious 3 nt (i think its a must for 2/1 players).

Someone posted a similar one to mine, i guess.

1♥--2♣
2NT-3♥
3NT--4♠ or 4 NT
5x---6♣
7♣/♥

2NT=bal hand no limit
3♥=forc
3NT=♠ cue with serious (good hand)
6♣ = asking Q ♣ for grand

I too like to use 4S! Kickback-RKC for ♥ as trump....

....but, then I'm fond of the Meckwell use of 4NT! as Voidwood for ♥, excluding the ♠ Ace

I am not sure that is specifically a Meckwell invention. I always assumed it was merely part of the Kickback convention, switching the normal meanings for 4S (in this case) and 4NT. Naturally in my suggestion you cannot use 4NT (or 5m) as exclusion when it is showing keycards so you need to give the void-showing response in this case. That is why it needs to be tested out practically, on whether the pros outweigh the cons or vice versa. In my relay system I use a bid of the Kickback step to show an undisclosed void on auctions where that is still possible but that would not work in this natural version since that bid is showing side kings.
