CRO

On 28 August 2020

This is a bridge acronym standing for:

Colour
Rank
Other

It’s similar to the Unusual NT and the Michael’s cue bid all wrapped in one. I think some people (me) have also called it Modified Ghestem as well.

It’s used to specify 55 distributions when the opponents have opened at the 1 level…the difference is you can specify exactly what suits the 55 are in where you might be left guessing using the Michael’s cue bid.

Same Colour (C)

So the Cue-bid (C) show at least 55 in two suits of the same colour…

Oppo Bid	Your Bid	Meaning
1♣	2♣	Shows 55 in the red suits
1♦	2♦	Shows 55 in the black suits
1♥	2♥	Shows 55 in the black suits
1♠	2♠	Shows 55 in the red suits

Same Rank (R)

This time the 2NT bid shows two suits of the same rank. Soif they bid a minor…you have at least 55 in the majors and if they bid the majors then you have the minors again at least 55.

Oppo Bid	Your Bid	Meaning
1♣	2NT	Shows 55 in the majors
1♦	2NT	Shows 55 in the majors
1♥	2NT	Shows 55 in the minors
1♠	2NT	Shows 55 in the minors

3♣ – The Other bid (O)

This one usually takes a bit more thinking about to work out but it’s easy when you get used to it!

Oppo Bid	Your Bid	Meaning
1♣	3♣	Shows 55 in diamonds and spades
1♦	3♣	Shows 55 in clubs and hearts
1♥	3♣	Shows 55 in diamonds and spades
1♠	3♣	Shows 55 in clubs and hearts

So the advantage of using CRO over say the Michael’s Cue Bid is partner knows what the other minor is:-

So if the bidding for example goes:-

Using a Michael’s Cue Bid


North	East	South	West
1♠	2♠	4♠	?

Suppose east has made a michael’s cue bid showing hearts and an unspecified minor. West might have a good sacrifice in Clubs but not have a sacrifice in hearts or diamonds…so he’s forced to pass as otherwise he’d be guessing to bid at the 5 level which could be a worse score than them making 4 spades.

This time using CRO


North	East	South	West
1♠	3♣	4♠	5♣
Pass	Pass	Double	Pass
Pass	Pass

This time West is able to bid clubs and find a good sacrifice…North south collect 300 for the doubled club contract but they could have made 4 spades vulnerable for 620!

The disadvantages of CRO are:

You tell the opposition what the other minor is
It’s slightly more stuff to remember
You lose the 3♣ bid as a natural bid
The opposition can use the minor as a cue bid as well

It sounds like I’m putting more negatives than positives but personally I think it’s worth it as I’ve found loads of sacrifices in the minors using this system and for me that outweighs the negatives.

Typical hands To use CRO

So these hands you could use CRO to describe your hand

♠ 4 ♥ KQ1076 ♦ AJ1073 ♣ 72
♠ AJ987 ♥ KJ1086 ♦ J7 ♣ 7

So I tend to visualise a hand with about 10 points

Hands NOT to use CRO

You wouldn’t do it with these hands:

♠ AQ ♥ 107654 ♦ J10873 ♣ K
♠ AKQ ♥ KJ1086 ♦ 65432 ♣ Void

The first hand you don’t have 10 points in the two suits…but you have some defensive values. The second hand again has a lot of your points in the other major.

Michael’s Cue Bid

By John Stell

On 23 June 2020

In Conventions

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….

Response	Meaning
2♦	Natural, good diamond suit (usually 6+) Non-forcing.
2♥	Sign-off…may be equal length as spades.
2♠	Sign-off…must be longer in spades than hearts though.
2NT	Natural and invites partner to bid 3NT
3♣	Artificial, game / slam interest in hearts or spades. Forcing.
3♦	A very strong diamond suit (6+ cards). Forcing
3♥	Preemptive, usually with 4 hearts
3♠	Preemptive, usually with 4 spades
3NT	To Play

So after 1♦ – 2♦ showing at least 5 / 5 in the majors….

Response	Meaning
2♥	Sign-off…may be equal length as spades.
2♠	Sign-off…must be longer in spades than hearts though.
2NT	Natural and invites partner to bid 3NT
3♣	Natural usually shows 6+ cards. Non-Forcing
3♦	Artificial, game / slam interest in hearts or spades. Forcing.
3♥	Preemptive, usually with 4 hearts
3♠	Preemptive, usually with 4 spades
3NT	To Play

So after 1♥ – 2♥ showing at least 5 spades and a minor suit as of yet unspecified.

Response	Meaning
2♠	Sign-off.
2NT	Asks for the minor
3♣	Natural usually shows 6+ cards. Non-Forcing
3♦	Natural usually shows 6+ cards. Non-Forcing
3♥	Forcing
3♠	Preemptive, usually with 4 spades
3NT	To Play

So after 1♠ – 2♠ showing at least 5 hearts and a minor suit as of yet unspecified.

Response	Meaning
2NT	Asks for the minor
3♣	Natural usually shows 6+ cards. Non-Forcing
3♦	Natural usually shows 6+ cards. Non-Forcing
3♥	Preemptive, usually with 4 hearts
3♠	Forcing…usually slam interest in hearts.
3NT	To Play

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.
