So my partner and I have a severe disagreement over the non-competitive auctions 1m 1M 2M

What hand shapes do you raise to 2M with only 3 card support? Does it change depending on relative strength of suits? Does it change depending on MPs vs IMPS?

We had the auction

1♦ 1♥
2♥ 2♠!
3♦?

Can this 3 diamond bid show only 3 hearts? is it possible that 3D actually shows only 3H and not 4 or can a x45x hand be possible?

I had

xx
Jxx
KQJxxx
Ax

Should this rebid 2D or 2H? All views welcome!

[gnasher]

I don't mind a style where the raise promises four or an unbalanced hand with three. I also don't mind a style where it can be a balanced hand with three card support and a low doubleton outside.

I think it's OK to bid 2♥ with a 2362 shape, but not with ♥Jxx and ♦KQJxxx. This will play well in diamonds even opposite a singleton, but 2♥ in a 4-3 fit will often be poor.

The meaning of 1♦-1♥;2♥-2♠;3♦ is a matter of agreement.

[mike777]

strongly prefer 2d not 2h, not close.

assume 2s is a game try and 3d is a counter game try, agrees hearts.

[Cthulhu D]

Yeah, rebid 2D. Seems perfectly normal, if P bids again you can support hearts.

I prefer a style where you raise on 3 only with a difficult bidding problem otherwise. For example:

S: x
H: Kxx
D: KJxxx
C: KJxx

1NT is a bit of a joke, 2S is of course out, not hugely enthused to rebid diamonds, leaving me with 2C or 2H.

2♦, I wouldnt bid 2♥ in a milion years.

[wank]

with this shape 2♥ is fine and many people play 2♠ (or 2NT over 2♠) as an enquiry to determine what type of raise you hold.

on this occasion though the diamond suit is too good relative to the heart suit.

[chasetb]

2362 minimums should be bidding 2♦ AT LEAST 95% of the time. When you have a good 6-card suit, rebid 2♦ EVERY TIME. Once you agree on Hearts as trump, you are stuck in playing Hearts, or rarely playing in NT. So 3♦ after you bid 2♥ and partner makes a game try is saying no for Spades (assuming natural), but I have too much to just sign-off.

[JLOGIC]

Some styles are bad

[perko90]

2♦. gnasher said it best.

[EricK]

In general, I like raising on 3 card support with a minimum unbalanced hand, but here, the only reason you opened this hand was the good ♦ suit, so you have to rebid it to let partner know. If you do play a style where opener frequently raises on 3, then in response to the asking bid, opener's bid below 3M should show 3 cards in the major; while higher bids promise 4. So in your sequence, if you have chosen to raise on a 2362 hand, then 3♦ shows that sort of hand (3♣ would show something like 1354; 2NT something like 4351). With a x45y hand you bid 3♥ if minimum for your raise, and something higher if not-minimum.

[Zelandakh]

How you play this depends on which system you are using. For example, in SEF or Forum D you never raise with 3 card support here. For the Anglo-American style, gnasher seems to have pretty much summed up the main options. On the given hand I prefer 2♦ to 2♥ and 2NT to 3♦.

[Phil352]

Fair enough this seems pretty conclusive. I probably should have mentioned that we were playing a weak NT and so 2353 hands are automatically discounted. When I play strong NT with another partner we frequently bid 2M with 3 card support and a small doubleton as gnasher suggested.

Am I right in thinking most people are looking at playing in the best/safest partscore rather than trying to help partner make a decision about borderline games where we have a double fit? For example would you expect partner to move again on eg. xxx KQxxxx Ax Qx? I guess he could bid 3♦?

Raising on a 3 card is quite alright when the alternatives are not appealing. I haven't had many issues after a 3 card raise when we avoided the following situatons:
- 1NT with a weak doubleton
- 2m on a 5 card suit (example 1c-1s-2c with 3-1-4-5)
- poor 6 card suit

The OP's hand has a good 6 card suit, so just do the normal thing and rebid 2d. Swap DK for HK and I'd probably raise.

I wouldn't think of passing 2♦. I wouldn't pass any rebid by opener (well, maybe 5♦).

[JLOGIC]

Wow playing weak NT makes raising so much worse too. That was pretty relevant info.

[fromageGB]

I never raise on 3 card support unless I have a singleton or void outside, so 2♦ rebid always on this hand. You can always support hearts later if needed. I like partner to be able to rely on this when he makes his next bid.

Apart from style, if 1♥ is unlimied, you seem to be giving up the idea of a diamond slam if you do bid 2♥. Partner will never know your diamonds are so good.

After the 2♠, 3♦ would confirm only 3 card support.

[awm]

It's really important to have agreements about this. There are definite advantages to raising often with three-card support, but a lot of them will be negated if partner does things like blast 4M on indifferent four-card suits in this auction. It's also good to discuss how you explore further after the raise (i.e. after 1♦-1♥-2♥ is 2♠ natural or an asking bid? does it set hearts or are other trump suits possible? if natural, is it a "help suit try" or always 4♠?). Without these discussions I would raise much less often on three than I do in my regular partnerships.

With suitable style agreements, I like to raise on three a lot, and will raise on three with 2-3-6-2 shape pretty often. However, this particular hand is all about the diamonds and you really should repeat them. I think the main consideration on this hand type is whether you would rather play a 6-1 diamond fit or a 4-3 heart fit (i.e. the worst fit likely in each suit). With such robust diamonds I think the choice is obvious. On a diamond suit like Axxxxx or even AKxxxx and a higher heart honor (or if the diamonds are downright lousy), the choice can easily go the other way.

[Phil352]

Justin how does playing weak nt make it worse? If anything surely it makes it easier for partner to know what to do since some hand types are automatically discounted?

I agree with Phil352 that

• It is a good idea to raise with three cards on some hands.
• Assuming that possibility in this auction then it seems natural to use 3♦ to admit to a 3-card raise.

IMO 2♦ = 10, 2♥ = 9. Decision is close.

It depends. Do you play:

(1) Weak NT with 5-card majors;
(2) Weak NT with 4-card majors, but opening the lower of two 4-card suits; or
(3) Weak NT with 4-card majors, but opening the major before the minor?

I expect that Justin's answer was assuming (1).

If you play (1) or (2), then a sequence like 1♦-1♥-2♥ is consistent with 15-16 balanced and therefore has a stronger upper limit than the same sequence playing 5-card majors and a strong NT (when the typical hand type for this sequence is a weak NT). Therefore, playing (1) or (2), you don't also want to be raising to 2♥ on unbalanced hands which are relatively weak for playing in hearts. Otherwise, how does partner know when to make a game try?

If you play (3), then yes you could agree that 1♦-1♥-2♥ is often a minimum 3-card raise.
