The auction (uncontested):
2C (strong) - 2D (waiting)
2H (Kokish) - 2S (forced)
3S (4-5 in majors, forcing) - 4H

Do you make a try for slam?

[luke warm]

pass is probably right, but i voted 4S... a question here is, what would 4NT by partner show? anyway, after 4S he has room to show a club, a diamond, a spade, none of the above

I have my minimum and no extra shape, think its kinda clear.

Pass seems clear.

Opener has already shown a good hand with 4-5 majors and he has nothing special here.

If slam is good, then responder maybe underbidding this one, as 4H is non-encouraging.

Responder may feels under pressure with good supporting hand for hearts, being forced to rebid 2S and has no room to agree hearts below game.

Imo, Kokish needs some works on responder's rebid and the continuation.
Playing 2S meaningless puppet would make responder start to describe his hand at 3 level or higher, and it is a difficult task.

A reasonable scheme (not recommended for casual partnership, or one that prefers simplicity at all costs):

2C-2D; 2H (hearts or big NT)-?

2S = default, usually balanced, may have long diamonds.

2NT = spades, (avoid wrong siding spades contract), denies 3H.

3C = clubs
*Opener, holding hearts, can make his planned rebid (unless he plans to rebid 3C, then he can go for slam hunt here). If he is big balanced, then he can agree clubs or rebid NT.

3D = diamonds, with heart support (a hand with long diamond will not directly bid it, as it may rob opener of his 3C rebid)

3H = hearts support, together with spades.

The exact requirements of strength is not listed here, and it is up to each partnership.

I am not sure whether Kokish worths it trouble, however, I am quite sure that some additional works to expound this agreement would help as the toy is so space consuming.

[luke warm]

well 4S seems to be a big loser on the voting (probably rightly so)... i still would like to know what 2c : 2d : 2h : 2s : 3s : 4h : 4s : 4nt would show... the reason i ask is, can that possibly show the ♠K? responder has already signed off, it seems unlikely he'd want to bid rkc now given that opener is cuebidding (and he shouldn't bid it anyway)

ok, so pass seems clear to everyone... i just thought it was worth a stab at responder having a couple of kings

I voted for pass
If partner has the right cards 6 might make, possibly consistent with an unimaginative 4H bid, but there is I think a greater risk of failing in 5H.

[mr1303]

The question I'm interested in is do you play 2H as double negative or something similar. If 2D is both waiting and negative at the same time, then partner can have something like

when you don't want to even be in 4H, let alone 5 or 6. Without any extra information, I assume that he might well do, and so pass

If slam is better than 50% then partner should have done something else other than bid 4H.
