This bid is used after an opening bid of 2NT showing 20-22 points where it can have a 5 card major. It’s used to find a 5-3 or 4-4 fit in the majors.

4♦

4♥
5/5 in the majors no slam try
4♠
5/5 in the majors slam try?
Opener bids 4NT to sign off or bids 4♦ over 4♣ to look for slam in clubs. Responder bids a major to show interest in slam in diamonds or bids 4NT to sign off.
It’s really critical you discuss this as a lot of people play this the wrong way and as soon as they hear 4NT they start answering RKCB. You shouldn’t play it this way in the minors…use the majors to agree a minor slam interest.
The Lavings convention is a simple way of asking for 5 card majors after partner has opened a strong or weak NT.
After an opening 1NT Bid and 2♣ Response
So it’s important to known you can only bid 2♣ with invitational hands.

The Bidding
a) 1NT (15-17) – 2♣ – 3♠ – 4♠
So the 3♠ shows a maximum and you simply raise it to 4♠
b) 1NT (12-14) – 2♣ – 2♦ – 2♥
Partner has invitational 5 card heart suit but after just bidding 2♥ you can pass this even with 3 card support.
c) 1NT (15 – 17) – 2♣ – 3♦ – 3♥ – 4♥
The original NT bidder is maximum with a 5 card diamond suit. You now bid your 5 card heart suit (game forcing) which gets supported to 4♥.
d) 1NT (12 – 14) – 2♣ – 3♠ – 4♠
The original NT bidder is maximum with a 5 card spade suit. You now bid 4♠.
e) 1NT (15-17) – 2♣ – 2♠
So the 2♠ shows a minimum with 5 spades which you can just pass.
f) 1NT (12-14) – 2♣ – 2NT – 3♣ – 3♠ – 4♠
2NT shows a maximum without any 5 card suit. 3♣ is promissory Stayman (it guarantees a 4 card major) and partner bids 3♠ which then gets raised to 4♠.
g) 1NT (12 – 14) – 2♣ – 2NT – 3♣ – 3♦ – 3NT
The 2NT shows a maximum without any 5 card suit. 3♣ is promissory Stayman (it guarantees a 4 card major) and partner bids 3♦ which denies a 4 card major. 3NT is then bid.
h) 1NT (12 – 14) – 2♣ – 2NT – 3♣ – 3♥ – 3NT – 4♠
The 2NT shows a maximum without any 5 card suit. 3♣ is promissory Stayman (it guarantees a 4 card major) and partner bids 3♥. 3NT is bid as you don’t like hearts and partner converts to the known 4-4 spade fit and bids 4♠.
g) 1NT (15 – 17) – 2♣ – 2NT – 3♦ – 3♥ – 3NT – 4♠
The 2NT shows a maximum without any 5 card suit. 3♦ asks for a 3 card major (should guarantee a 5 card major) and partner bids 3♥. 3NT is bid which partner can either pass or bid 4♠ if they have 3 card spade support.
So that’s how to play the Lavings bidding convention….a five card major ask after an opening 1NT.
The Michael’s cue bid is a very popular bidding convention to show distributional hands…hands usually with at least 55 shapes (5521).
This Michael’s cue bid is usually used in the direct position, i.e., immediately after an opponent has made their bid.
All these direct overcall bids are known as Michael’s cue-bids:-
Opening Bid
Direct Overcall
Shows
1♣
2♣
5+ hearts and 5+ Spades
1♦
2♦
5+ hearts and 5+ Spades
1♥
2♥
5+ spades and 5+ unspecified minor
1♠
2♠
5+ hearts and 5+ unspecified minor
For example if your right-hand opponent opened 1♥ and you bid 2♥, your 2♥ call would be a Michael’s cue-bid. This would show at least 5 spades and at least 5 card in either clubs or diamonds.
If your right-hand opponent opened 1♠ and you bid 2♠, your 2♠ call would be a Michael’s cue-bid. This would show at least 5 hearts and at least 5 card in either clubs or diamonds.
Better still if your right-hand opponent opened 1♣ or 1♦ and you bid the Michael’s cue-bid.
This would specifically show 5-5 (or longer) in the majors. This is better for you as you know exactly what two suits partner has.
What about points?
So that’s the shapes and the suits…but what values should you have for the bid?
Typically I imagine a hand like:
♠ KQ1072 ♥ KQ1073 ♦ 4 ♣ 75
You can play several methods but usually either a weak hand (say, 6 to 11 points) or a strong hand (a good 15 or more high-card points). Hands with intermediate strength should simply overcall at the one level, with the hope that the second suit can be shown later in the auction. Why do this? It’s to give partner some indication of our strength and involve him in the decision process as to how high we compete (sacrifice).
Responding to the Michael’s cue bid
So after 1♣ – 2♣ showing at least 5 / 5 in the majors….

Bidding in 4th position
You can also use it to show 5 / 5 in the other two suits like:
North
East
South
West
1♣
Pass
1♠
2♣*
Now the 2C bid shows 5 /5 in diamonds and hearts.
OR…..
North
East
South
West
1♣
Pass
1♥
2♣*
Now the 2C bid shows 5 /5 in diamonds and spades.
You could also have a different meaning for the other cue-bid:-
OR…..
North
East
South
West
1♣
Pass
1♥
2♥*
Now the 2♥ bid shows 5 /5 in diamonds and spades….but a stronger hand 15+
Another alternative….
North
East
South
West
1♣
Pass
1♥
2♥*
Now the 2♥ bid could show longer spades than diamonds at least 6/5. This is because you have bid the higher cue-bid.
And now….
North
East
South
West
1♣
Pass
1♥
2♣*
Now the 2♣ bid could show longer diamonds than spades at least 6/5. This is because you have bid the lower cue-bid.
So the Michael’s cue bid is a great way of letting your partner know your shape using just one bid….of course it does tell the opponents as well which means they might stop out of a game if they know the splits are bad. Quite often these bids can be used to find a good sacrifice.
Make sure you have an agreement with your partner…like I said a common one is to show the hand as either weak OR strong.
Alternatively you can play a bidding convention called CRO (Colour/Rank/Other). Using the CRO bidding convention you can specify what the other minor is.
After a strong 2♣ and 2♦ relay (waiting bid). Now the 2♥ bid forces 2♠. Now the 2NT bid shows 25+ points if the bid of 2NT shows 23-24 points.
Partnerships can have different points holding for 2NT openers so make sure you have a partnership agreement as some people play 20-21 2NT openers.
Let’s look at some examples of 2♣ openers using kokish relays :-
a)
b)
c)
d)
♠ AK ♥ AJ10 ♦ AQ532 ♣ AK7
♠ AKJ5 ♥ AQ9 ♦ A87 ♣ AK5
♠ AQ10 ♥ AK ♦ QJ104 ♣ AQJ10
♠ Q103 ♥ AQJ ♦ AQJ ♣ AK96
♠ QJ732 ♥ 98765 ♦ 5 ♣ 42
♠ 107 ♥ K108632 ♦ K52 ♣ 43
♠ 7432 ♥ 543 ♦ 987 ♣ 973
♠ KJ954 ♥ 42 ♦ 1074 ♣ 743
a) 2♣ – 2♦ – 2NT – 3♣ – 3♥ – 4♦ – 4♥.
The 2NT bid shows 25+ points. partner bids muppet stayman and the 3♥ response denies a 4 card major. Partner bids 4♦ to show 5-5 in the majors and 4♥ is reached.
The 2NT bid shows 25+ points. Partner bids a two under slam try 4♣ and partner accepts with a cue bid of 4♦. Partner does a quick check for keycards and decides 6NT is a better contract.
c) 2♣ – 2♦ – 2♥ – 2♠ – 2NT – All Pass
The 2NT bid shows 23-24points.
d) 2♣ – 2♦ – 2♥ – 2♠ – 2NT – 3♣ – 3♥ – 3NT – 4♠
The 2NT bid shows 23-24 points. 3♣ is muppet stayman, 3♥ denies a 4 card major, 3NT shows a 5 card major and partner bids 4♠.
The kokish relay is a useful system for keeping the bidding at 2NT when you have these 25+ point holding allowing partner to investigate major holdings below the 3NT level. The disadvantage of this system is in order to agree hearts you can end up bidding 4H…
2♣ – 2♦ – 2♥ – 2♠ – 3♥ – ? harder to agree hearts without signing off in 4♥
Where the bidding previously may have preceded with….
2♣ – 2♦ – 2♥ – 3♥ – now can look for a slam in hearts more comfortably
So it’s up to you if you want to play the Kokish relay system…how often do you pick up 25 counts?
Multi-Landy is a convention used after the opponents open 1NT. It gets its name from the use of the Landy 2♣ overcall and the Multi 2♦ convention. One purpose is to more precisely identify major-suit fits.
The conventional calls over 1NT are as follows.
Bids
Meaning
Double
Penalty 15+points (particularly against a weak 1NT). Against a Strong NT it shows a 4-card major with a longer minor. Double after passing shows a 4-card major with a longer minor.
2♣
At least 5-4 or 4-5 in hearts and spades. 8-15 points
2♦
5+ hearts or 5+ spades (no side suit). 8-15 points
2♥
At least 5-4 in hearts and a minor. 8-15 points
2♠
At least 5-4 in spades and a minor. 8-15 points
2NT
At least 5-5 in clubs and diamonds. 8-15 points
Minimum points usually at favourable vulnerability or/and when 55 or 6 card suits…don’t bid vulnerable with garbage!
Some example hands that might use this convention are:
1)
2)
3)
4)
♠ AQ102 ♥ K10963 ♦ 4 ♣ K75
♠ KQ10942 ♥ A8 ♦ 842 ♣ 75

♠ KJ763 ♥ 8 ♦ AQ109 ♣ Q76
5)
6)
♠ 9 ♥ 84 ♦ AQ1085 ♣ KJ763
♠ AQ ♥ K98 ♦ QJ1095 ♣ KJ8
Hand 1 would bid 2♣ showing at least 5-4 in the majors
Hand 2 would bid 2♦ showing a 5+ major without a second suit.
Hand 3 would bid 2♥ showing 5 hearts and a minor suit.
Hand 4 would bid 2♠ showing 5 spades and a minor suit.
Hand 5 would bid 2NT showing 5-5the minors
Hand 6 would simply double against a weak NT for penalties

To Play
Please note that these notes are merely ideas on how to play this convention…but you can change them how you want. That is one of the main points about complex bridge conventions…that you can change them to how you want to play them…as long as you agree them with your partner…that is the crucial point.
In Competition
Obviously when you overcall 2♣, the opposition might double this contract which might show clubs, they might bid diamonds…so it’s important you have an agreement what double, re-double or 2♦ means from partner?
I would suggest over 2♣ double, Redouble asks for the longer major and 2♦ is now natural.
Over a 2♦ bid double asks partner to bid their longer major.
The support double is a double, as the name suggests, which shows just 3 card support for partners bid MAJOR suit. Most partnerships just play this up to the 2 level.
Also if a double is made of partners suit then a re-double by partner also shows 3 card support.
If you are playing support doubles it means that bids of partners suit show 4 card support.
Let’s look at some examples
All of these are example of support doubles.
Auction 1
1♣ – P – 1♥ – 1♠
D*
Shows 3 card heart support
Auction 2
1♣ – 1♦ – 1♥ – 2♦
D*
Shows 3 card heart support
Auction 3
1♣ – P – 1♠ – 2♦
D*
Shows 3 card spade support
Auction 4
1♣ – P – 1♠ – 2♦
2♠
This now shows 4 card support because you didn’t double.
Auction 5
1♣ – P – 1♠ – D
RD
The RD doesn’t show extra points it just shows you have an opening hand and you’ve got 3 spades in your hand.
If we start with an auction with no intervening bidding such as:-
1♠ – 2♣
2♠ – 3♠
?
If we have agreed an 8 card fit in the majors then most of the time it’s going to play better in 4♠, therefore if we give up the 3NT bid as a natural bid, we can use it for something more constructive….The Frivolous 3NT.
Based on the principal of fast arrival 3♠ here can show a better hand. We can now use 3NT as the more useful Frivolous 3NT conventional bid.
So what are the kinds of hand that would bid 3NT, cue bid, or just bid 4♠?
Hands that would bid the Frivolous 3NT
a)
b)
c)
d) We open 1♣
♠ AQ10863 ♥ A62 ♦ K84 ♣ 7
♠ KQ10754 ♥ KQ8 ♦ 3 ♣ K65

Which auctions are Frivolous 3NT?
So in all the following Frivolous 3NT applies….
Auction 1
1♠ – 2♣
2♠ – 3♠
3NT
Okay if you cannot spot this as frivolous 3NT you’re in trouble!
Auction 2
1♠ – 2♥
3♥ – 3NT
The Frivolous 3NT convention may be used by either partner as this is a 2/1 game forcing auction.
Auction 3
1♠ – 2♥
3♥ – 3♠
3NT
Frivolous 3NT may be used after an intervening cue bid.
Auction 4
1♠ – 2♣
3♣ – 3♠
3NT
Frivolous 3NT may be used after an intervening raise of responder.
Auction 5
1♠ – 2♦
2NT – 3♠
3NT
Frivolous 3NT applies even if opener rebid a natural 2NT as long as the major is raised.
Auction 6
1♠ – 2NT
3♣ – 3♦
3♠ – 3NT
Frivolous 3NT applies after any game forcing raise of a major, even without a 2/1. Here the responses are to Swedish Jacoby.
What Auctions aren’t frivolous 3NT?
Auction 1
1♠ – 2♣
2♠ – 2NT
3♣ – 3♠
3NT?
Here the 3♠ bid only shows 2 card support so the 3NT can be natural.
Auction 2
1♠ – 2♣
2♥ – 2♠
3NT?
Jumps to 3NT aren’t frivolous…you can simply cue-bid over 2♠ or bid 3♠
Auction 3
1♠ – 2♣
2♥ – 3♠
3NT?
3♠ is a strong picture jump raise therefore the Frivolous 3NT is not needed when the partnership is already known to be in the slam zone. This could be a case of wanting partner to cue bid 4♣ before you bid 4♦
Auction 4
1♠ – 2♦
3♠ – 3NT
The 3♠ bid is similar to the last auction is a strong picture jump suit rebid setting the suit. Frivolous 3NT is not needed since the partnership is already known to be in the slam zone.
Auction 5
1♠ – 1NT
2♣ – 3♠
3NT
Since the 3♠ is a 3-card limit raise. Here the Frivolous 3NT is off since responder’s 3♠ raise did not create a game force.
RKC Minorwood is a bridge convention which looks for all the keycards in a minor suit at a lower level that the normal 4NT RKCB
If you play inverted minors for example then the sequences will fit into this system:
1♣-2♣-4♣
So here 4♣ is RKC minorwood and the responses are:-
4♦ – 1/4 Keycards
4♥ – 0/3 Keycards
4♠ – 2 Keycards
4NT – 2Keycards + Queen of clubs
A Next suit bid up would ask for the Queen of clubs.
A 4NT bid would be a sign off and a 5♦ would be the specific king ask…where the response are to cue bid your kings or bid the king you haven’t got if you have 2 kings. Here you can use hearts as diamonds, spades as hearts and NT’s as spades.
So a 5NT bid would show the king of spades or the King of diamonds and hearts.
1♦-2♦-4♦
So here 4♦ is RKC minorwood
4♥ – 1/4 Keycards
4♠ – 0/3 Keycards
4NT – 2 Keycards
5♣ – 2Keycards + Queen of diamonds
A Next suit bid up would ask for the Queen of trumps
A 4NT bid would be a sign off and a 5♣/♥ would be the specific king ask…where the response are to cue bid your kings or bid the king you haven’t got if you have 2 kings.
If you bid 5♥ to ask for kings…then you need to use spades as clubs, NT as diamonds and clubs as hearts.
So a 5♠ bid would show the king of clubs or the King of hearts and king of spades.
Again this is another bridge convention that people play in different ways…so you really need to make sure that you and your partner are playing it the same way before you agree to play inverted minors.
This version i’m going to describe I play with a prepared club (might only be a 2 card suit) and a 5 card diamond suit (unbalanced) with a strong NT.
So the whole point of inverted minors are that the 2♣ and 2♦ bid replace the 3♣ and 3♦ bids in normal Acol. In simplistic terms at least. However there is more complexity to it than that….
Let’s start with 1♣ – 2♣
This shows 10+ points, a 5 card club suit and is forcing to 2NT or 3♣.
2♦ = 15+ points or natural diamonds
2♥ = A heart stop, and possibly no spade stop or getting ready to show a 5 card suit.
2♠ = A spade stop, and possibly no heart stop or getting ready to show a 5 card spade suit.
