Considerations about opening bid with this hand as dealer all vul? IMP / Matchpoints differences?

My style is opening 1♣ but others say 3,4 or 5♣

I'd try 5♣, followed by double if opps butt-in.

[Blofeld]

5♣ looks normal at any scoring/colours.

Not keen on 3♣ or 4♣. At least a 1♣ bid has noble goals (even if it is misguided ; how do you show this hand in a delicate slam auction?).

[zimzam]

My 1♣ opening style is for bidding space and possible slam aucion, but off course I could be forced to 5 level next round anyway. 5♣ is putting tremendous pressure on opps I agree

5♣ any colors/scoring seems normal. For each time you miss a biddable slam, I'm sure there will be 10+ times that the preemptive effect of this either causes you to win the board or not lose the board.

I play a convention with regular p where a 4NT opening shows a very sound 5m opening (that is, a hand that would normally open 5m but is concerned that the partnership will miss a slam) If this option was available, would you use it? 4NT does give them extra bidding space.....

5♣ seems right when V, I wouldn't do it when NV...

I play a very similar convention (It's documented in preempts from A to Z by Zenkel and Andersen)

It might be useful to review their requirements for a 4NT opening:

1. An excellent 8 or 9 card suit
2. sound playing values for the 5-level (9+ playing tricks)
3. No more than one loser in any suit

They provide the following example hand

♠ 7
♥ 7
♦ A6
♣ KQJT98543

The club suit is way too weak to even consider a 4NT opening...

[pclayton]

With my sane partners, we don't allow preempts with 2 outside defensive tricks.

I'm stuck with 1♣.

[EricK]

Is nobody opening 1♠ to ensure the best lead against the opponent's 6♥ bid?

I would consider 5♣ if red. So I do not totally meet the sanity test.

Hi,

5C looks about right.
This may change a bit, if
you exchanged the x with
real cards, but not a lot.

The specific cards may be
relevant, vul. vs. non. vul. 4C
since they mmay make 4C look
a bid more attractive.

With kind regards
Marlowe

Do the specific spot cards matter all that much in a 9-card suit? You'll probably be able to draw trumps in two rounds, and whether you do this by winning or losing the tricks depends mostly on what honors partner is nice enough to show up with. You're not likely to be taking any finesses in ♣.

I'm willing to wager that if I have a 9 card suit, its gonna be trump.

Accordingly, if we're going to have any kind of controlled auction, partner needs some mechanism to determine the expected trump losers opposite his hand.

I see three reasonable possibilities:

1. Open at a low enough level that partner can ask about the trump suit
2. Use a disciplined opening bid (IF I am playing a disciplined opening, it makes more sense to show a solid/semi-soild suit than a weak one)
3. Don't try for a controlled auction

Stephen suggesting using an artifical 4NT bid to show a good 5 level club preempt...
This precludes option 1 + 3. Ergo, I think that he needs to promise a good club suit.

[Joe de Balliol]

3C as an opening bid is hideous, 4C only slightly less so. Pass, 1C, and 5C are the only things I consider [maybe 6C late at night...] and I go for 5C with no qualms.
