MPs, 4CM weak NT:



Do you rebid the hearts or show the diamonds here?

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

Is my partner called Boris ? ;)

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

2H

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

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.

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.

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.

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.
