CHECK BACK STAYMAN
The Stayman Convention (or 2 Club convention) is used by the responder over partners opening bid of 1 No Trump (or 2 No Trump). The purpose is to find a 4/4 fit in a Major suit. The responder should have at least 4 cards in one or both of the Majors. There are, however, other occasions when the Stayman Convention can be used. And one such occasion is when the is in the DMZ.*
        In example 1 below the responder's first bid was 1 D. She might have a long Diamond suit and a 4 card Major. In this case she wants to CHECK to see if opener also has a 4 card Major. To do this responder rebids 3 C. This bid is called CHECK BACK STAYMAN. In example 1, the 3 C bid is not support for partners 1 C opening bid, but a request that partner bid a 4 card Major. In this case the DMZ opener bids her 4 card Major, or if none the 3 D. This is just like regular Stayman over a 2 NT opener. The use of CHECK BACK STAYMAN in example 1 allows the DMZ opener to bypass the bid of 1 S or 1 H over partner's  1 Dresponse. The direct jump to 2 NT does not deny 4 cards in either one or both of the other Major suits.
 
1. OPENER              RESPONDER 
     1 C                               1 D

     2 NT                              3 C

       In example 2 below the responder's first bid was a 1 H. Responder might have 4 cards in both Hearts and Spades. (she bids 1 Hor "up the ladder" with 4/4 in the Majors.) Then the subsequent 3 C (CHECK BACK STAYMAN) bid by the responder gives the DMZ opener a chance to show 4 cards in the other Major (Spades). The responder is hoping partner has a 4 card Spade suit. (Then game is 4S.) If there is a Major suit fit then responder goes to game in that suit. If no fit, then responder bids 3 NT. This use of CHECK BACK STAYMAN in example 2 allows the DMZ opener to bypass a bid of 1 S over partner's 1 H Response. The direct jump to 2 NT does not deny 4 cards in the other Major suit. 
 

2. OPENER             RESPONDER 
     1 C                             1 H

     2 NT                           3 C

       Also in example 2 above, responder might have a 5 card Heart suit and is asking if opener has 3 card support. (This is similar to the New Minor Force.) Note: a 3 H rebid by the DMZ opener over 3 Cshows 3 Hearts. For if opener had 4 Hearts, she would have jumped to 4 H immediately over responders first bid of 1 H and not bid 2 NT. 
        In example 3 below responder could have 5/5 or 5/4 in the majors and is looking for a major suit fit. Again she uses CHECK BACK STAYMAN. A 3 S rebid by DMZ opener shows 3 Spades.  A  3 H bid shows 4 Hearts 
 

3. OPENER                RESPONDER 
       1 C                             1 S

        2 NT                           3 C

         Note: in all three of the above examples the 3 C bid is artificial and not necessarily a show a suit nor support a partners 1 C opening bid. The 3 Club bid is always CHECK BACK STAYMAN. Responder need not pass partner's game  bid. She can make a slam try or bid the slam directly. 

* The DMZ is a hand that falls between a 1 NT opener and a 2 NT opener.  The bidder shows this type of hand by jumping in No Trump
