Responder must take into account opener's minimum HCP count & 3rd hand openings!
Rubinsohl is not used over a simple overcall. (only over weak 2 jump overcalls made at the 2-level
say OR good values in opponents suit. Partner (a good one!) will re-open with a protective double
or a second suit
With a major
pre-emptively - 2, 3 or 4 level;
Over a 2-level response, trial bids operate.
2NT!: A sound raise to 3-level

4♣|♦! see SWISS bids: Good raise to game with 4+ card, Balanced 15+
With a 4+ card Ma' At the 1-level a 4 card major must be bid with 4+
HCP. 1-level bids are to be treated as forcing. A 1NT rebid by
partner is 12-16 balanced. At the 2-level 5+ card suit 4-7 HCP is
required & announced as non-forcing. A new suit by partner follows 5-4 rule
With a minor
fit Single raise 10+, see Inverted minors Pre-emptive minor raises to 4|4|5 levels;
2NT!: A sound raise to 3-level & 4+ card support - same as for Major opening!
FORCING see Negative Double

(4 card major OK at 1-level);
Pre-emptive Jumps in

NT contract if partner
guards 'X' well.
3Y 2-suited. At least 5-4 in the unbid suits
To play, Natural, Solid
guard in 'Y' .
Note: A 1NT rebid by opener is structural. It shows 12-16 HCP Crowhurst, (2♣
inquiry shows 9+) it does not promise or deny
a guard in 'Y'!
However if responder has passed then 1NT rebid is 15-18 with Crowhurst (2♣
Opponents make a 2-level simple overcall
a 2-level new suit bid without jump shows <10HCP and a 5+ card suit.
a 3-level new suit bid is pre-emptive!

- Partner should be prepared to 'PROTECT' if feasible.
(9)10+ at 2-levell
Natural 3+ card support. Competitive. 1♠
4-9 HCP Natural 4+ card support. Competitive. 1♥
Following these simple Major
raises, opener will usually PASS wih sub-opening values, may make a
simple 3-level raise invitationally, bid game, bid a new suit - a trial
bid -forcing to 3-level, cue-bid is also a trial bid. If RHO also bids
then raises are competitive, new suits are trial bids.
5.-9 HCP pre-emptive with distributional values.
10+ unlimited inverted minor raise. May hide a 4 card major.

3-level competitive Major raise - with 4(3 Spades
Shortage (0-1) in opponents suit with game
values. Forcing. Probable 3+ card support for partner but could
be a strong 2-suited hand 5-5 or better in the remaining suits. Opener
must rebid a second suit if present or failing that rebid with a
moderate 6(5) card suit or bid 3NT with a strong guard in a flattish
hand (5332 or 4333)
means about 1 1/2 Trick short of a 'limit'
raise made without the intervention
2NT NF rebid by opener following a negative double (9+) is 12-15(16),
natural with a Guard in 'Y'. Unbid
minor is now an inquiry
3NT NF rebid following a negative double is Natural, with good 'Y' guard: To Play
2NT NF Natural following any new suit at 2-level is a denies support of responder's suit but promises good guard in 'Y'.
With a weak Jump overcall: 1X-J2Y(opp)-?
This is the first duty! Direct raises are distributional limit bids
No fit. Possibly values in 'Y' - partner invited to make a
protective double with good defensive values.
Opening values over 3-level intervention 11+. Probably interest in the
other 2 suits. Can be
converted to penalty

below with shortage (0 or1 card)
Mandatory with 16+ with exception of SWISS & 4NT

ERKCB, agrees partner's suit
Opening values, shortage in 'Y': 0-1 card - 5-5 or better in
other 2-suits. No fit with 'X'
With a 1NT strong overcall (Not unusual type): 1X-1NT(opp)-?

Opponent is showing values and controls in your partner's suit
A common bid in this sequence!
(9)+ HCP All distributions
- invites partner to rebid a 2nd suit or rebid a 6+ card major or PASS for penalties
Bid new suit Not
favoured! If an excellent 5 card suit with invitational values use
Rubinsohl or Double
Can be used with a 7+ card suit weak.
Major 2X At least minimum
support: 3 card spades
or 4 card Hearts & 5-(9) HCP with a TOP honour! a
limited & competitive distributional bid
3|4X At least 4 card support - requires good distributional values-
competitive - use LTC.Note: The issue with raising partner is the knowledge of trump controls with
the 1NT bidder. These raises are safer only when holding at least a top
Raise minor 2X: 10+,
4+ card support (inverted minor) - ignore holding a major suit
3|4X distributional - competitive
(9)10+ Rubinsohl - transfer to 3C, Shows 6 card club suit
A continuation to Partner's suit shows 3 card support.
Rubinsohl transfers to 3♦♥♠
Shows a 6+ card new suit and denies support for Partner, however if a
transfer to partners suit it shows 4+ card support invitational. all other transfers denies any
usuable support for 'X' .
Transfer to 3NT (available - but this must be rare!)
Note: Transfers are preferred to put 1NT bidder on lead.
OR: INT 'unusual': 1X-1NT!(opp)-?
Usually showing a long minor or interest in minors (alertable) or our own multi NT!
Single Raise of partner Limit bid
(not pre-emptive) shows 4 card support & likely to be distributional
SWISS Solid raise to at least the 4-level, Balanced
(No voids or Singletons)
leaves all options to partner - but denies fit
2 New suit
HCP, 5+ card suit
2NT,3♣♦♥ (9)10+ Rubinsohl transfers, Show a good (5)6 card new suit
; transfer to partner's suit shows 4 card support
Rebids after ....2NT!-3♣
. Show a 5+ good card suit & a good control
in lowest unbid minor.
Transfer to 3NT
With a 2-suited bid (Cue-bid, 2NT or 3♣ etc)
Raise partner E.g. 1♥ - (2♥ or 2N or 3♣) - 3|4♥ shows limit raises to 3|4 level
4♣|♦ SWISS balanced, Solid raise to game,
Slam potential (maybe short in opponents bid suit)
Forcing. Any new suit. Agrees partners suit. Shows Control maybe
2-3 cards. Forcing to
game. Partner may
3NT or 4 of his Major. Slam bidding will be
TURBO. If partner cue-bids, bids 4NT or higher.
(9)10+ Negative Double.
No fit. Usual potential support for unbid suit(s)
3-level Double (11)12+
Negative Double. No fit. Can be converted to penalties. Partner may
also continue with an unbid suit.
3-level Pre-empt e.g. 1♠-3♦(opps)-?
Raise partner - as above
Negative * - as above
New suit - as above
Shows game values, A good guard, support for unbid suits. Partner has options : PASS to play 3N; bid his 2nd suit;
or game in his 1st suit
Note the imperative reason for this 3NT bid is the lack of bidding
space when opponents pre-empt you to the 3-level. We have ways to
show game support: balanced: 4mi or unbalanced: either new suit
with control or directly bid game or Double then game see above sums
this up) but there is no other good way to explore both
the other major and a NT game. This is a reminiscent of the
sequence: 3mi-3NT...where one major is shown and looking to plat 3NT or
game in the other major.
Overcalls of 2♦ Multi e.g. 2♦-Y-? or 2♦-*
PASS: with nothing to say. Partner will protect if strong: 3-suited 3C|D, 2NT or a Protective double
with a balanced hand. Also, if weak, competitively discloses a good
6 card major 2S, 3Ma competitively
Double: shows a normal 2NT response. Partner develops his hand normally
