6 Note 1: Opener rebids 1NT: 2 forces 2 [all invitational hands], then Pass = weak 2M = balanced 5crd suit 2oM = 5/4 2N = invitational balanced (in principle denies 5M) 3m = 5crdM & 4crdm 3new = 5/5+ 2 is GF shape ask, usually with balanced or semi-balanced hand Rebids by both sides are natural and up the line with 2N used as a waiting bid 2M is to play 2oM is p/c if showing 5-4, or inv 4-4 if reverse 2N is a transfer to 3 [weak????] 3any shows distributional GF, 5/5+ Note 2: Opener raises to 2M: 2M+1 (enquiry): Opener may sometimes raise responder s M with 3crd support if a NT rebid is flawed. With game interest, responder may enquire with 2M+1, then: 3new ( * ) = shortage & 3crd support [Opener may now pass 3M by Responder if min] 3m = no shortage, 3crd support & min [3M now by responder is to play] 3M = no shortage, 4crd support & min 3N = no shortage, 3crd support [or 4M-3-3-3] & max JS = shortage & 4crd support 4M = no shortage, 4crd support & max ( * ) note 1m - 1, = shortage & 4crd support 1m - 1, N = shortage & 3crd support Note 3: Opener reverses at the 2-level: Opener s 2-level reverse is F1 but not 100% GF. Any bid by Responder other than 2N will however create a GF. 2N by Responder is Lebensohl, asking Opener to bid 3, and R can then show a weak hand and pass or make a NF re-bid. Suit below 2N is natural, NF 2N is trf to 3 [Note, with a GF hand Opener must break the Lebensohl trf to 3, and instead show their hand type naturally. This applies in all Leb situations.] 3-level bids, natural and GF

7 Note 4: Opener jump rebids 2NT: 3 = checkback; then 3 = 5crdm 3 = if M= then: 3crd and not 4crd (3 by R would then be a cue-bid) = if M= then: 4crd and not 3crd (3 by R would then be a cue-bid) 3 = if M= then: 4crd may have 3crd (If R now bids 3N, O has rights to bid 4 ) = if M= then: 3crd may have 4crd (3 by R would then be a cue-bid) 3N = Not 3M or 4oM or 5m 3 = if M, then 6+crd suit demanding cue; if om then 5/5 in Majors (O cues to agree, and bids 3N to play) 3 =if M, then 6+crd suit demanding cue; if om then 4/4 in Majors (O cues to agree, and bids 3N to play) Note 5: Inverted Minors: 3m = to play opposite minimum limit raise. Responder may now bid 3m+1 to ask about shortage: O now bids: - shortage (4m shows suit above and kickback applies) - 3N without shortage It is recommended that all hands which are GF start via the relay all other shape showing bids will show extra values, but R can attempt to sign off in 3m if unsuitable. Responses to the relay: after GF 2m+1 2M = shortage 2N = balanced 13+ [3 asks for range with 2pt step responses step1=13-14, etc] 3m = 6crd suit, inv, no shortage 3Relay = shortage 3N = balanced, Note 6: Forcing NT: 1-1N - Then 2 = 2+crd 2 / = 4+crd / 2 = 6+crd 2N = 18/19 bal 3 = artificial GF 3 = natural GF

Then 4 would be kickback If R does not relay it is an attempt to sign off even opposite GF hand.
