1N-2D opener generally bids 2H.  The only way to super accept H is to bid 2S.

 

1N           2D           2H           2S=relay forces 2N then:    

3C=4441 or 4450 force.  If opener cues singleton = total control ask 4D= Redwood

3D=4414 or 4405 force. Opener cues singleton = total control ask. 4C= Redwood

3H=5/5/majors invitational.

3S=5/5 majors force.

4S=3244 quantitative

1N           2D           2H           2N=natural, opener can bid 3C, 3D to further game try.               

1N           2D           2H           3C,3D=natural force does not promise slamish values.

1N           2D           2H           3H=natural invitation         

1N           2D           2H           3S=long H forcing. 3N asks singleton responder then shows singleton at 4 level

1N           2D           2H           3N=natural           

1N           2D           2H           4C=slam try no shortness, opener bids step bid with acceptance, opener may bid

                                                out         

1N           2D           2H           4D= slam try better trump no shortness          

1N           2D           2H           4H=slam try weaker trump no shortness         

1N           2D           2H           4N=quantitative

1N           2D           2S            Only heart super accept.  Responder bids 2N with heart length.  Opener

generally rebids 3C, allowing responder to retransfer (3D).  All other responder bids shown hand types of relay above.
