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
