Reverse Drury

Similar to Drury, Reverse Drury is a way to check if partners 3rd or 4th seat opening bid is light or of full values. Reverse Drury has the added feature that the 2 bid promises support for partners major suit opening, and some play that it promises 4 card support.

Since it promises support, the opener rebids his major suit with a light opener, and may bid another suit or 2nt as sound opening bid.
