Responses to 2-suited Bids.
1 minor - 2 minor - 7+ points at least 5/5 in the Majors.
Because the bid does not promise a large point count Responder should only take preference to 2 of a major unless having a strong hand or good fit.
Responding in the other minor - Partner has shown the Majors so bidding the other minor shows a long and strong suit and shortage in the majors. It suggest that partner leaves you there unless very strong.
Responding in NTs - These responses are natural with stoppers and denying interest in the Majors. The minimum for a jump to 3NT would be a 15 count with some help in the Majors so as to establish them. 2NT is only invitational say 12-14.
Responding in a Major. -
2H/S - These deny any interest in game and won't have a big fit. With equal length respond in hearts. It will normally deny opening values unless short in both M.
3H/S - These bids show a good fit and are invitational based on distribution rather than high cards so will have less than 10 points.
Cuebid Response - As always the cuebid shows 10+ with an interest in game if partner has more than a minimum.
Responses to the cuebid - define strength and distribution -
3H = Any minimum so 7-10 - now the bidding can stop in 3H or in 3S if that is the rebid by cuebidder.
3S = Some extra values so 11+ - spades equal or longer than hearts.
4H = Some extra values so 11+ - hearts longer than spades.
3NT shows a stopper in the opened suit and 11+ points with 5/5 distribution.
4m = strong hand say 14+ with values in the bid minor.
1Major - 2 Major - shows opening values+ with 5/5+ in the other major and a minor.
Responding in partners Major when partner shows spades and a minor -
2S - weak hand - may only have 2 spades.
3S - good fit not a strong hand.
When partner shows hearts and a minor -
3H - heart fit but not a strong hand.
Responding in a minor -
3C - is weak and asks partner to pass or correct to 3D.
3D - is weak and asks partner to pass or correct to at least 4C.
4C/D - are based on a good fit and ask partner to pas or correct.
2NT Response – 10+ with interest in game asking for description.
3C/D to show his second suit and a minimum - say 10-14 ish.
3H/S to show 15+ and 5/5 (H=C, S=D). These are game forcing.
3NT = 15+ with 5/5 distribution and a stopper in the opened suit.
4C/D to show a very distributional hand with some extra values.
If opener bids 3C or 3D the sequence is not forcing and responder must jump or cuebid to force. A return to overcallers Major is invitational or why bid 2NT first.
1 of a Major - 2NT - shows opening values+ with 5/5+ in the minors.
Responding in the other Major - Shows a long strong suit and is not forcing. I suggest partner is invited to raise a major with good top cards.
Responding 3NT - This is to play so opening values with stoppers - remember the lead will come through your hand.
Responding in partners suits. -
3C/D - weakish hand not forcing. - if overcaller bids on show shape or a stop in the opened suit.
4C/D - more preemptive than strong.
Cuebid - game interest - asks stopper and/or range.
Responses - 3NT shows a stopper - any range - now removal to 4C/D is invitational in that suit and a cuebid is a slam try in a minor.
4C - a minimum with no stop - now 4D is to play.
4D - extra values could still be 5/5.
5C - extra values longer clubs.
Cuebid in a Major - control in a strong hand. (4NT = strong hand and controls in both Majors).
I of a minor - 2NT - shows opening values with 5/5+ in hearts and the other minor.
Responses are very similar with 3 of partners suit not forcing.
A cuebid can be used as a game try in hearts as a response of 3H shows a minimum.
