(2M-Weak)-5♣-(p)-?
(2♦-Multi)-5♣-(P)-?
 
Is 5♣ preemptive here. 2♦ can include strong variants..Is 5♣ over 2♦ more preemptive then over 2M-weak?
..Or should 5♣ be constructive (you don't want to DBL followed by bidding ♣ because opps could preempt too much)?
What would you need to bid 6♣ after your partner did overcall 5♣?

..Was this question too easy or too difficult? Or is there no 'standard' for 5♣ here?

Is 5♣ preemptive here.

No. It's to make, taking into account pard will usually have 7-8 hcp. Expect 9-10 playing tricks for the bid and a very distributional hand.


2♦ can include strong variants..Is 5♣ over 2♦ more preemptive then over 2M-weak?

No, because 95%+ of the time the multi is weakish. (If the strong variants came up like 30%+ of the time, you might have to make some changes.)


..Or should 5♣ be constructive (you don't want to DBL followed by bidding ♣ because opps could preempt too much)?

Preemption isn't a big issue here. With a strong hand, you should prefre 5♣ to double when it is a more desciptive bid.


What would you need to bid 6♣ after your partner did overcall 5♣?

The best hand would be fit + aces + control of opps suit. It's hard to tell, really, but one thing you should NOT do is to raise with the same 7-8 hcp already took into account Here's what might be a good raise to 6:

(2♠) 5♣ (pass) ..?

If you double a natural 2M, there is a strong suggestion that you have something in the other major so would probably bid 5m with some hands that would have started with a dbl against multi.

So maybe 5m over multi should not be particularly strong. Without discussion I would expect it to show the same playing strength as over a natural 2M, though.

Btw agree with Whereagles.

5C bidder must assume 1+trick to be reasonably sure not shut out too often. 5C claims 1+ trick of making. 6C needs at least A better than 1-trick and consider why no cue first? No control?
