Playing your preferred natural system (but no transfer responses to 1♣), please select all that apply.

I assume that the "stronger/weaker than 1n rebid" is meant to be "stronger/weaker than 1n opening" unless I'm completely misinterpreting.

(at least in strong NT context)

Corrected; I mean "same strength as a NT rebid" (which is weaker than a 1NT opening, in a strong NT context).

[steve2005]

mostly play mp, so always rebidding 1N as were a weak NT so want to get back with field who opened 1N. At imps 4-4 concentrated vales will rebid 1M.

Adam, I don't know why you are using the term, "the same strength as a 1N rebid". The requirements for 1♣ - 1♦ - 1M is based entirely on shape, with a very wide HCP range.

Walsh partnerships can decide if they want to require a 5th club, or just a weak doubleton in the unbid suit for 1M. Up the line isn't part of Walsh, but for poll completeness I guess its OK.

The second part of the poll is entirely about balanced hands. Obviously everyone bids 1♠ with an unbalanced hand.

Since most people open 1NT with balanced hands in range, there are basically two ranges of balanced hands which open 1♣. One of these is the range that normally rebids 1NT (for strong notrump openers, this is 12-14 or the like; for weak notrump openers its 15-17 or similar). The other is a stronger range (18-19 in standard, but for some people probably 17-18 or 17-19). I believe there are people who bid up the line on a weak notrump hand but will never rebid 1M with the stronger hand (preferring 2NT).

I knew I should play xyz after 1♣-1♦-1M, and that I should bid 1♣-1♦ with strong 4-4, yet I don't for simplicity when playing with most of my partners (Clients)

[Vampyr]

"INV" above is somewhat ambiguous. If it means "invitational after a 1NT rebid", then the range will vary a lot depending on the NT range in use. If it means something else, like "invitational values opposite an opening 1-bid", then how does one define 8+ HCP?

[mycroft]

Hmm. I would explain my reasoning, but it would look like I'm quoting steve2005. 1M rebid "Tends to show an unbalanced hand".

[rmnka447]

Playing weak NT in all seats, 1 NT rebid shows strong NT, so we always make the NT rebid with a balanced hand.

A 1 ♦ response shows diamonds. If we have a major and bid ♦, it will be a hand where we are willing to reverse into the major.

We play

1 m - 1 x
1 M - 2 ♣

as a bid asking opener about his HC strength. 2 ♦ by opener shows a minimum range hand, any other bid shows extras. Responder makes the 2 ♣ bid on any hand with an invitational raise opposite a more than minimum opener. Responder can then take the appropriate action dictated by the strength of opener's hand.

We play this convention to allow showing the major with any unbalanced hand minimum or not. Without it, opener would have to rebid his minor to limit his hand and hope to find the major fit in subsequent bidding.

In this context, the auction

1 m - 1 x
1 M - 3 M

is absolutely forcing and shows a GF hand opposite a minimum opener.

[Winstonm]

I admit my knowledge is not current, but the way I learned and still understand this sequence is that opener bids 1N after 1D to simply describe a weak NT hand, assuming 1NT opening is strong. At the level of 1N, stoppers and specific shapes are not as important as limiting strength and shape with 1 bid.

[mike777]

1) 4s 5+d(not 4d)
2) never with balanced hand
3) xyz puppet to 2d

[mgoetze]

Hard to shake the feeling that some people missed that this was a multichoice poll. Anyway, my votes should be taken with the caveat that all the options presented were actually rather far from my truly preferred systems.
