RHO opens 1S, you hold Qxx xx KQx KQ10xx. Will you overcall 2C? Do you think most of your peers make the same choice?

[lycier]

Very good !
This is a classical hand which is suitable for bidding at balabced seat,not for overcall,whatever vulnerable or non-vulnerable.
so my choice is all pass and never overcall.

[Adebisi]

Good hand,opening strength, seems automatic 2♣ bid, only pass after passed partner.

[Fluffy]

Do I have 6 card suit? No, do I have extra strengt to compensate? No. So no overcall, I don't expect the others to do the same but they are stll wrong.

If playing Ghestem I supose you should even overcall less, since 2♣ bid is already overloaded with some 3♣ preempts.

*** The cheapest space-consuming overcall, lead-directing with HKQx side stuff, SQxx defensive quack,
blabbing stuff with a "minor that won't win this declaration", partner with SKx and CA tries 3NT but not 6+C.
What upside does anyone see? What hands would be left to reopen - a rag 8?
PASS.

I think my choice to o/c at reds & IMPs is best described as a quirk. Team opponents have good uses for 1NT and 2C responses, and I will take the risk to interfere with those. Nail me.

[Phil]

Good problem, since my choice differed with all three vulnerabilities.

This does not mean I had a good answer.

[lalldonn]

It's very important to include whether or not partner is a passed hand, in my opinion. (I will use that as my lame excuse to not answer yet)

[han]

Partner is not a passed hand.

[JLOGIC]

w/w MP, w/r imps, w/r MP.

I could see myself sometimes overcalling w/w at imps, not sure what my standard action would be, it is the only debatable one in my mind.

[gszes]

Too little to gain and the balanced nature of our hand means even finding
a good sac is unlikely. If p is so weak they could not have balanced there is
a huge probability we have nothing offensively. This means our 2c bid will
most likely result in either helping the opps in the play of the hand or in
finding a better contract or both.

I am more than happy to let p do the majority of the work in the PO seat
and let them know Im stronger than expected with a nice cue bid. If p
is too weak then at the worst I am leaving the opps to find their way with
as little help from me as possible.

I much prefer to be able to back into the bidding with this type of hand if the
opps show we own half the deck or more:)))))))))))))))))))))))))))))

To quote Lady Thatcher: No, no, no.

[steve2005]

2♣ this a great hand, sure no A's and Q♠ is not pulling its weight, even with out QS have 10 pts
However, you want partner to lead ♣ against NT and probably suit contracts too and this might be last chance to mention them.

[lmilne]

Favourable I usually end up bidding. I'm not sure how good this is opposite a passed hand, but I want partner to lead clubs and possibly interfere with their auction.

I would probably pass at nil matchpoints opposite a passed hand but bid otherwise. I think at IMPs I would pass at nil in 2nd seat but it would depend on momentum factors etc.

[MrAce]

Never

[lalldonn]

I will say only when w/w or w/r at mps.

[jogs]

Vul: never. Non-vul: rarely. Must be known weak opponents.

LHO has singleton or doubleton spade. The first three tricks
are ♠K, ♠A, spade ruff. This hand looks unlucky.
