MPs, 4CM weak NT:

---

Do you rebid the hearts or show the diamonds here?

[DavidKok]

I'd show the diamonds, but the 4cM system might indicate a different bid. I'm not sure.

[pescetom]

Is my partner called Boris ?

Count me in for diamonds, so long as that also lengthens the hearts to five.

[P_Marlowe]

2H

This should show the 6th heart, if it still could be 5332, than 2D.

[apollo1201]

Playing 5CM, I was told to try to show the 4m suit if it is not too weak. Here KQxx are plenty enough.

Not playing 4CM, I don’t know how you show a 5th heart in a balanced hand, as I presume, 1NT will be 15-17 with 4. Does this mean 5M332 need to be opened 1NT when in range? Or 1NT means weak w/ 5 or strong w/4 and partner has some kind of complex check back?

So I’d prefer to show 9 of my cards instead of « 5 maybe 6 »

In Std Am or 2/1, with the 6-4 hand, you rebid the 6 card suit first with a minimum opener and the 4 card suit first with a stronger hand, the reason being that, if your partner does take a second bid, you can play in 3 of the second suit in the first sequence but not the second.

This is a minimum opener, so 2H.

But I don't know how it works with 4 card majors.

[AL78]

I decided to show the six card suit and bid 2♥. The full deal:

Making 10 tricks when the heart queen doesn't drop but 3NT also makes 10 tricks which one pair found so we only got 1 out of 4 MPs. I don't know how they got there as it was played by North.

3N is ludicrously lucky to make 10, it needs favourable layouts in spades and clubs, swap the ♣AQ and make them 5-3 with spades 4-2 and see how well 3N plays on a diamond to the J or a small club, you can still make 4♥ with a correct club guess.

The joy of matchpoint scoring, getting rewarded for poor bidding ending up in a poor contract which happens to score better thanks to a specific layout of the cards. This is one reason I prefer teams.

[thepossum]

Initially I thought only rebid hearts but I am leaning towards 2 diamonds
Now to read the thread

What system are we playing.

Just put it through one of my bidding test and South jumped to 2 spades which means 3 diamonds and not 2

MP is ok, just not 2 Table.

In American systems, 5M(332) is typically treated as a balanced hand and so opened 1NT when in range. In these systems it is also quite common, but not universal, for weak 6-4 hands to rebid the major and for a bidding sequence of M-M-m to show a different range from M-m-M.
In central European systems (SEF and Forum D) 5M(332) hands are treated a a separate hand type from normal balanced hands, which means that there are sequences devoted specifically to these, at the cost of often being a level higher than for American systems. In these systems, it is also standard to rebid the 4 card suit for 6-4 hands.
Finally, in Acol rebidding the 4 card minor also promises 5+ cards in the original major, so you get to show 5 cards with the rebid instead of just 1-2 (depending on how 5M(332)s are treated). For this system, it is generally clear to rebid the 4 card suit.

[the hog]

Standard amongst good players is to rebid the 6 card Major with weaker hands and to bid the 4 card minor with stronger hands.

2♥ -- the 6-1 will play almost certainly play better than a 4-3 if partner passes 2♦, and the rebid might coax a raise.

How will the 6-0 do against a 4-6 if partner has scraped up a response on their minimum 4063? There are pros and cons to both approaches and cherry-picking a particular hand to suggest your preferred style is the only one is just disingenuous.
