Jump in new suit in competitive auction

[EricK]

The auction starts:

1♣ (1♦) 1♥ (P)

2♠

 

Is there a standard meaning for this 2♠ bid? What do you think the best agreement would be?

 

Bonus questions: Assuming the same first round, what are the standard meanings for these bids by opener? And what do you think the best agreements are?

2♦?

3♦?

4♦?

2s: same as in the noncontested auction

2d: usually 15+ with 6 c + 3 h and.that is what responder should assume in first instance. Could also be some max opener without.diamond stopper.

3d: splinter

4d: void splinter

[WGF_Flame]

2S - normal

2D - 3Hs (same as support double no need extra or club length)

3D - ask for stoper usually based on strong club suit.

4D = spliter

Basically what helene wrote, except that I do not think 2♦ needs to be quite so specific:

 

2♠ = nat GF

2♦ = all the hands that are awkward, including strong 3 card raises without a better option and 18-19 bal without diamond stop; you can also throw minimum 3 card raises in here too if you like

3♦ = splinter

4♦ = void splinter

2♠ is a normal reverse, like opps didn't even intervene

2♦ is a general force which doesn't know what to do (GF with 3 or 4 card fit, balanced hand without stopper,...)

3♦ is a splinter with ♥ support

4♦ is a void splinter with ♥ support

Thanks for the replies.

 

My partner bid 2♠ on a GF 3415 hand - which didn't work out well when I had genuine support for his ♠. I suggested that this wasn't the wisest bid to make undiscussed; but he claimed it was standard (or he'd read it in a book) that 1♠ showed ♠ and 2♠ showed something in ♠ and ♥ support. Now I'd come across "fragment" bids before, but wasn't sure if it was this kind of auction. Also, i was pretty certain you had to have agreed them first.

 

When he asked what he should have bid, I suggested 4♦ as I felt 2♦ was a general force and 3♦ was primarily looking for 3NT (which is a sort of combination of some of the answers above!). Is it that useful to split the splinters into 2 immediately? I suppose one is spoilt for choice on this auction in that the opps haven't taken any room away, and have given you a handy low-level force on many awkward hands.

I suspect your partner was getting confused with the auction (1♦) - 1♥ - (P) - 2♠. It is not uncommon to play this as a fit jump, showing heart support, good spades and enough (offensive) strength for the 3 level. However, a typical thing to hear from some pairs is that "all jumps in competition show fit". The questions are whether this auction counts as "in competition" (it can be if you agree it to be but then either 1♠ needs to be forcing or 2♦ includes the GF spade hands) and also when fit jumps are on, if they have been agreed at all. Sometimes, a little reading/knowledge can be a dangerous thing. There is a difference between "a good idea after (much) discussion" and "Standard".
