2¨ showing 19-21 balanced or ¨ force

Responses 2© = ª transfer then

2ª = minimum. If responder raises to 3ª he shows only 5 trump as to right side game contracts.

If responder rebids 2NT he shows a six card ª suit asking opener to cooperate

2NT = ª super accept with 19-21 balanced. Responder may retransfer with 3©

All other calls show ¨ force. 3ª would show ª super accept with ¨ force .

2ª = transfer to 2NT then

3§ = stayman (opponent doubles stayman principles apply)

3¨ = © transfer If responder rebids 3ª he shows shortness.

Opener relays with 3NT to ask, responder then cues singleton (© = replacement for ª)

3© = minors (3♠ by opener suggests interest)

3ª = ♣ transfer (with medium values)

2NT = § transfer (either weak or strong) then

3¨, 3©, 3ª = shortness

3N = quantitative

4¨, 4©, 4ª, = exclusion bw

3§ = ¨ transfer then

3©,3ª = shortness

3NT = quantitative

4§ = shortness

4©, 4ª, 5§ = exclusion bw

3¨, 3©, 3ª, 3NT = 4441 (each bid shows suit below singleton NT = ¨)

Interference over 2¨

After overcall, x = negative with values to accept 3NT (Pass with 0 count)

Opener reopens with x on correct shapes, reopens with 2NT on absolute maximums , other reopenings show ♦ force

After 2© or 2ª overcall 2NT, 3§, 3¨, 3© = transfersohl as after 1NT opening
