An Auction

(1♦)-P-(1♥)-1♠

(P)-3♦/♥

[jdonn]

I've never thought about it. I know that a level lower I would take 2♦ as natural and 2♥ as the spade raise. I could probably translate that logic a level higher and say 3♦ is the meaning of an unbid suit (fit jump for me) and 3♥ is the meaning of a cuebid (mixed raise). But I'm not sure how useful that is to be honest.

[kenrexford]

Never thought about it either, but the fit-jump meaning for 3♦ makes a heck of a lot of sense. I also would attribute a similar meaning to 3♥ as mentioned by Josh. So, I suppose two votes.

Well, we have thought about it, which doesn't mean our decision is wonderful. But we use both jump cues as mixed raises, with shortness in the one we bid.

 

Two-level cues are the opposite --length and invite with support.

(1♦)-P-(1♥)-1♠

(P)-3♦/♥

show the stopper you have?

[Siegmund]

My reg p and I use them both as mixed raises, but unlike aqua we jump in the suit we have the stronger holding in. Seems more likely to help us make an intelligent cooperative decision about whether to bid on or defend if the opps compete again; holding severe shortness, one can decide on one's own to compete one level higher in our suit.

 

(Actually, we have this agreement primarily when 2nd hand overcalls: after (1♦)-1♥-(1♠), advancer's 2♦ is limit, while 2♠ and 3♦ are both mixed. The posted auction is a logical extension of the above.)

2D is not forcing, which makes 3D natural and forcing, LDO? Maybe people who play new suits forcing after an overcall disagree, but if you think 2D is NF it is strange to me to not have a way to force in diamonds.

 

2H is a cuebid, 3H is a mixed raise. Diamond bids are not cuebids once you've passed diamonds and then start bidding diamonds.

If you play 1h-1s-p-2d as NF, which seems common enough, is it LDO that 1h-1s-p-3d is forcing with diamonds? I would expect there to be no way to force with diamonds on either of these auctions.

No, only because people don't know how to bid :)

 

LDO was just an inside joke, I have long believed it to be "ldo" to play a new suit NF, and a jump shift natural and forcing, but a lot of people make fun of me for this simplistic approach. Call me crazy but I think being able to bid a strong hand with a suit is more important than being able to make a fit jump, or a weak jump when you already have a way to show the suit, or whatever.
