Is it really necessary to have an agreement? Surely partner can work out that 3S is stronger than 2S but weaker than 4S.

I don't know about that - 3S sounds a lot like a slam try to me.

Compare your description to msjennifer's and discuss.

Some have an agreement that over a drury call, 3M asks for cuebid of any aces. So I suppose it depends on how much partner knows, and how much he thinks you know, as to whether he'll be able to work out your meaning of 3S or not.

There are many ways a partnership can develop the auction after using Drury or Reverse Drury.Using simple Drury,If one has not discussed anything then the most SAFE bid is just 2S which is forcing for one round.It is for partnership to give various meanings to any other bid than 2D ( which is conventionally used to show a sub or minimum opening) Thera are many other ways to express a desire to investigate a slam possibility.Anyhow,We Personally feel that 3S does not show a slam possibility.After a suit fit is found we use the LTC method and not worry about the total HCP.We use the SST and LST to investigate slam possibilities after a suit fit has been clearly established. Accordingly the 3S bid suggested by me shows exactly 6 losers outside the spade suit and a super strong spade suit.I play Precision system and so even if a similar sequence arises when using that system the HCP are limited to 11/15HCP.Howevever,My comments are assuming only any Standard system like SAYC for example.I sincerely hope I have made the things clear.

Even using "standard" Drury, 2S isn't forcing - it just says "I have a real opening but I would not accept a limit raise". So you're already veering into custom agreements there. Added to the point that essentially nobody plays "standard" Drury any more, so almost everyone would take 2S as a sub-minimum, means that 2S is in no way a safe action on this hand.

More pertinent to the original post, both you and Graham asserted that 3S has a specific meaning. Without more detailed agreements that this partnership clearly does not have, stating that 3S has a specific meaning and that this hand is perfect for it doesn't help answer the question in the initial post. I'm glad your agreement works for you, but it has the potential to confuse people who don't know Drury all that well.

MPs, you open 1S in third, partner bids 2C drury (max passed hand with a fit).

Let's say you can only bid 4S or 3N, which do you go for?

Unquestionably 4♠ The two doubletons point to a trump rather than a NT contract
With 6 losers I want to be in game. and since partner cannot guarantee stoppers in the side suits,
I need the safety of trumps. 3NT is a contract that will go down among the dead men
