Partner must respond to
this 1NT overcall following an opps opening of 1mi, if other opp
passes, either by announcing a 4+ card Major: 2H or
2S or else 2NT. If RHO has bid showing a Major suit of precisely
4+ cards, then double shows the other Major, otherwise PASS if RHO made any bid
then PASS denies a Major AND if opp passed and you do not hold a Major
bid 2NT to keep the bidding open.
Its very important to show your Major if you have one as it allows the alternate contract of a Major game if partner has a fit!
If opps have intervened use PASS - when NOT
holding a 4 card Major. Either way partner now has a rebid capability
of 3 in his minor unless a 4-4 Major fit is exposed: then a raise is the
required bid. Otherwise the 1N o'caller should call 3 of his minor,
Partner's rebid is usually in his 5+ card minor except when
when a major fit is located. Bidding his minor suit or showing a major 4-4 fit
bids .
Bidding then continues as with 2Ma openings with cue-bidding and use of
4NT TURBO.
Blackwood has not proved to be a good way to
continue:- bidding experience has shown a strong tendency to bid
failing slams via 4N following a 2Ma opening. Although the 4N option is available our preference is cue bidding and a TURBO 4N.
This revision is pleasing in the sense that BETA now has a
'minor' equivalent to our long time sucessful sequences following
2Ma opening!
Importantly this approach discovers any 4-4+ major fit
promptly.This is a critical outcome as a Msjor game needs to be
discovered as a priority. It also could sid redirection towaeds a 3N
game. These investigated before closing in a minor contract.
