DRURY

[calabres]

Hi all

 

I know that Drury is played in diferent ways by bridge players.

 

I like a lot my way, that is:

 

After 1 ♥ or ♠ 3th seat oppening:

 

-------------------------------------------------------------------

2 ♣ = 4+ c. 8/11

 

2 ♦ by ptn to know my strenght:

 

2 ♥ = 8/9

2 ♠ = 10/11

-------------------------------------------------------------------

2 ♦ = 3 c. 10/11

 

 

I had lots of joy playing this, cause full info for ptn to bid game or try slam.

 

Regards

Interesting. A sort of reversed Drury, not opener showing but the answerer showing! :wacko:

Why not. It it perhaps better to let the still undiscovered opener make the asking.

Interesting-an extension of the popular two-way drury convention except that 2D shows 3 card support and 2C 4 card support, and allowing one to find the range of the 2C 8-11. Nice :)

Personally I prefer to use 2♣ and 2♦ as encrypted drury, designed to confuse my opponents while still being constructive. Taking spades as an example,

 

1♠ - whenever light in 3rd seat, must have A or K of trump

1♠ - 2♣ - Drury with exactly one of the A or K of trump

1♠ - 2♦ - Drury with either both or neither of the AK in trump

 

After the 2♣ response, often opener will have the other honor - either since he is weak and must have it, or if sound, will often have it. In those cases, the game tries and signoffs can be encrypted so the opponents won't know what is going on (and in cases where we aren't sure, we revert to normal methods).

 

After 1♠ - 2♣ :

 

2♠ - light signoff (with A) or balanced minimum (with K)

2♦ - light signoff (with K) or balanced minimum (with A) or any sound hand (with neither)

2N - encrypted 2-way game try (responder shows cheapest help suit with A, cheapest missing help suit with K)

3♣♦♥ - encrypted short suit game try in suit bid (with A) or in next higher suit (with K)

 

All rebids except 2♦ confirm the encryption. After a 2♦ bid that might be sound with neither honor, responder must bid 2♠ with the A (since 2♦ might be weak), over which sound openers may make a natural, unencrypted game try. Responder with the K (hence knowing opener is sound), he may make a natural, unencrypted game try over 2♦ (since opener might not have the other honor) or bid 2♠ to show a balanced minimum.

 

Observe that the sequences P-1♠-2♣-2♠-P and P-1♠-2♣-2♦-2♠-P could either be a weak hand signing off, or alternatively one hand showing a balanced minimum and the other declining to invite game. These are two very different situations from the opponents' perspective of whether or not to balance in the auction.

If i must play drury in a p/u game ...prefer novice drury.....will leave increapted to the real experts.

Instead of Drury, why not play Fit Non Jumps by responder? This will provide a useful bit of information to opener if he happens to have a proper opening, and will offer an alternative part score if opener happens to have a 4 card major suit and a minimum hand.

It seems like an interesting idea.

I'd like to hear people positive and negative experiences using it.

All the Israeli juniors used this.

Calabres,

What do you bid if you have 12 points (outside your 8/11 range)?

How about 13?

It's a passed hand. With 12+ hcp he would have opened the bidding last round. :lol:

Encryption is illegal, unless you play outside the WBF.

You're not allowed to use bids or signals if the key to untangle the meaning is hidden from the opponents.

 

It's possible that it might be allowed playing online - but I doubt it.

I can't speak for the WBF, but in the US encrypted carding/signals are banned, but not encrypted bidding. Of course there are much fewer cases where encrypted bidding is practical (as opposed to encrypted signals, like varying your 3NT leads from 4th to 3/5 based on if you've got >8 pts vs not).
