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.
