zenbiddist Posted May 4, 2020 Report Share Posted May 4, 2020 Playing a style of 2/1 where Opener's 2NT Rebid is 12-14 bal or 18-19 bal, obviously the bigger hand bids again.With a doubleton in Responder's suit, it makes sense for Opener to rebid 4NT quant. My question is, would 4♣, 4♦ and 4♠ over 3NT in this sequence show three card support for Responder's minor and a slammish 18-19 bal hand?[hv=d=w&v=0&b=8&a=1hp2dp2n(12-14%20or%2018-19)p3np4c]133|100[/hv] It seems logical to me playing this 2NT rebid style, but I've never read/talked about it, and I usually play a different structure.

DavidKok Posted May 4, 2020 Report Share Posted May 4, 2020 I'd argue that opposite 18-19 bal with 5332 shape and no major fit the most likely slam is 6NT even if you have a 5-3 fit in a minor, so I'd probably interpret this as a general cue bid, neither promising nor denying diamond support. Also I think this two-way 2NT is a bit shifty - the bidding is already GF, and now opener needs to introduce artificial bids at the 4-level to show his strength. Normally 2/1 avoids this, bidding slowly with strong hands. Quote Link to comment Share on other sites More sharing options...

Normally 2/1 avoids this, bidding slowly with strong hands. I was taught to respond 2NT as 12-14 and 3NT as 18-19 (17+ over 1M).Not sure what disadvantages this has compared to a two-way scheme, the advantage of clarity is obvious.

smerriman Posted May 10, 2020 Report Share Posted May 10, 2020 I was taught to respond 2NT as 12-14 and 3NT as 18-19 (17+ over 1M).Not sure what disadvantages this has compared to a two-way scheme, the advantage of clarity is obvious.I would have said the advantages of going slow were fairly obvious also - eg what if responder has heart support and was planning to make a delayed raise of 3♥ then start a cuebidding sequence? If the right spot is no-trumps, you can always show your strength later; if not, you get the extra room to find it. A poll was done on the 3NT bid at BW a couple of years ago - far and away the most popular option (45%) was a 15-17 that wasn't suitable for 1N, with 28% voting for 18-19 options, 12% saying never bid it, and 8% some form of minimum. Many of the voters / commenters who voted for it showing 18-19 said they'd still go the 2NT - 4NT route for suitable 18-19 hands. Quote Link to comment Share on other sites More sharing options...

E.g. if you are 2524, you get a much more defined auction if you first bid 2N and then follow-up with 4C. If you start with 3C, and partner bids 3♥ (which he often has to do on a doubleton), then what next?4D would show 3-card support. 1 Quote Link to comment Share on other sites More sharing options...

msjennifer Posted May 19, 2020 Report Share Posted May 19, 2020 Sir ,to me it sounds a club cue with an honour to three D support and of course 18-19 HCP as per the bidding understandings mentioned. Quote Link to comment Share on other sites More sharing options...
iandayre Posted May 22, 2020 Report Share Posted May 22, 2020 Seems to me it would show the higher range, with concentration in C with relatively weak S. Quote Link to comment Share on other sites More sharing options...
