Drury is a conventional 2 response by a passed hand after partner opens 1 or 1 in third or fourth seat. The 2 bid is artificial, showing a limit raise with 10-12 support points and 3+ card support.
Playing Drury, responder can keep the bidding low at the 2-level instead of making a jump raise. Since many partnerships open light in third or fourth seat, responder wants to bid conservatively opposite a weak hand.

|2||A sub-minimum hand (10-12 points)|
|2||A normal opening bid (12+ points)|
|All other bids||Natural, with normal opening values (12+ points)|
