[Al_U_Card]

Use 2D (this hand has a higher frequency than most other uses of 2D except perhaps multi). Flannery players can use 2H as the 5H4S 11-16 hcp hand bid.


Pass ....To play (a weak hand with a diamond fit).
2 H / S....To play (opener raises with a maximum and 3 card support).
2 NT........Asks for a description of opener’s hand (Looking for 3 NT.)

Resp. 3 C – Min. with no major suit stoppers. ||Resp. passes or corrects to 3D.
Resp. 3 D – Min. with one major suit stopper. ||Resp. shows his stopper(s).
Resp. 3 H – Max. with a spade stopper. || Responder bids 3 NT or 5
Resp. 3 S – Max. with a heart stopper. || of a minor to play.
Resp. 3 N – Both major suits stopped. ||
Resp. 4 C – Max. with no major stoppers. || 4 level bids are ace-asking.
5 level bids are to play.
3 C…..…To play.
3 D…..…Shows 4+ diamonds, with only one major suit stopped. Opener
shows stoppers etc.
3 H / S.…Forcing for one round. Shows 4+ cards in the suit, an opening hand,
stoppers for no-trump and a fit for at least one of the minor suits. Opener
raises with 4 card support (or a good 3 and a max.); re-bids 3NT with the
other major stopped, or re-bids 4C .
3 NT......To play. No fit in the minors and both major suits stopped.
4 C/D……Pre-emptive bids.

How about opening on the 1-level?

[Al_U_Card]

It is about non-natural* systems, and it is also about the lies you tell when you rebid.....

[luke warm]

i don't see anything wrong with 2♦ for the hand you show, except maybe there's a better use for that bid... however, in general i'd rather just keep things simpler and open 1♦ (or 1♣)

Open 1♠ like in MOSCITO

[helene_t]

In the Borring Club system they open this shape (slightly narrower range) 2NT.

I don't see the merrit of those conventions, presumably you can't open 1♦ with this shape for some reason. Can you decribe all 4441-shapes, and 5431-shapes with a bad 5-card clubs + 4M, in your system?

This 2d wont get you to good scores, it has many flows.About your structure it spends too much energy on not trumps showing stopers, instead of fits.
the 3 level bids like 3h to show 4 card doesnt seems right.

[pclayton]

4-5's used to be a problem. They aren't anymore.

Rebid 1N with a stiff or raise on 3. No need to misdescribe by opening a canape here.

The idea of playing at the 3 level opposite a ?-?-1-2 is not appealing either.

If you want to use a 2 level bid for this call, perhaps make a 2♦ opener the strong bid and use 2♣ as the 4-5. 2♥ can still be Flannery.
