P P 1♠ P
2♣ DBL 2♦ ....

2♣ is Drury and 2♦ shows a weak opening bid! or does it?

When a conventional call id DBL'd should the meaning of responses be changed?.

Similar opportunities exist when Stayman, Jacoby, Bergen etc. calls are DBL'd. There are conventions like ROPI DOPI specifically designed to combat similar situations.

My question, then, is this. Is there a prevailing method of improving my bidding methods when the opps DBL a convention bid.

I like to play the same responses.

RDBL now shows a desire to play in the dbled contract. If my bid was going to be a catchall bid, pass shows the catchall now.

Not sure if this is the best approach!

To start with realize that the double by your opponents of your partner's artificial bid gives you extra options -- you can pass or you can redouble. Discuss with your partner what those will mean.

Realize as well that you might want the meaning of the double to affect the meaning of your subsequent calls.

I'm not aware of any "prevailing methods" (except for DOPI/ROPI) for bidding after doubles of artificial bids. Perhaps others here will have some suggestions.

Most important - Discuss with your partner. Better to ignore the double and keep the same meanings for your call than to make a bid that partner won't understand.

Our meta-agreement for responses to doubled artificial bids is:
pass: the suit named (here clubs)
rdbl: neutral/weak relay (here a hand that would otherwise have bid 2♦)
2♦: natural (here: must be a long suit trial)
3♣: short suit trial
Others unchanged.

Don't play regular Drury please. Play Reverse Drury, so 2♦ shows a full opener.

I've never discussed this, but with the double, pass should be a defensive minimum. 2♦ should be a full opener. 2M is still drek, but not a lot of defense. xx should be a suggestion to play.

My meta agreements leave me in no doubt that bidding 2♦ or 2♥ would show that suit, 2♠ would show the worst hand, redouble would show clubs, and pass would show the equivalent of 2♦ before.

Helene, I think you should have two sets of agreements for these situations. Yours for auctions where you are likely to be in trouble and trying to find a safe resting place, like (1NT) 2♣ (X) where 2♣ is majors. Then it makes sense for pass to show the suit bid so you don't have to play it redoubled. But auctions like the given one, where you have a fit you could safely return to and thus will only play in clubs if you really think you are making, it's better for redouble to show the suit and pass to be neutral.
Please let me know about any questions or interest or bug reports about GIB.

Thanks. My immediate thought is that I would be worried about messing it up. For example if NMF or FSF gets doubled we don't have a known fit to return to but OTOH we should have enough values to not be in trouble.

Gonna discuss it with p.

Go with the second option, assume you are safe. Perhaps a better way to think about it is go by the meaning of their double, if they are trying to penalize us then assume we are in trouble, if they are just showing a suit them assume we aren't. That's more like what I meant, I explained it poorly the first time when I said it was based on having a fit.

So Pass becomes the "weak call", all others would promise a full opener. Presumably, RDBL or Suit bid would be an attempt to get to game in ♠.

Read it again. He said 2♠ would be the 'worst hand'.

If you insist on playing regular Drury for some odd reason, 2♦ would be the worst hand.
