Reverse Drury

Every time we have 10+ points and 3+ support for partner’s third-seat major suit opener, we respond 2♣. This is an artificial bid, which must be alerted.

2♥	Natural game try
2♠	A hand that would not have opened 1♠ in first or second seat, either light in HCP, or only 4 spades. Must be alerted.

Most of the time, responder will simply sign off in 2♠. However, if you have a distributional hand with seven losers that was not an opener because it lacked the quick tricks, you can make another try for game by showing your long suit, and trying to find a double fit.
