Playing Checkback, I don't like opener to rebid at the 3-level, though some pairs use these to show shapely maximums. Are they right?

For instance:
1♦ - 1♠
1NT - 2♣
3♥ ??

Assume 1NT rebid = 12-14. Responder may not want to hear 3♥ with

♠AQT5   ♥A73   ♦KJ762   ♣8

Assume this is a suitable hand for checkback followed by 3♦ forcing, in case 5♦ or 6♦ is better. Or

♠AJ65   ♥5   ♦T6   ♣QT9875

2♣ then 3♣ is the normal way to sign-off in 3♣. Many (most?) play 3♣ directly over 1NT as strongish, maybe 5-5.

What is usual in your neck of the woods?

I don't know wich checkback you are using, nowadays I play XYZ (2-way checkback I think it is also called).

I used to play 'Roudi' wich is a checkback with step responses:

1x-1y
1NT-2♣

2♦ minimum with 2 cards in y
2♥ minimum with 3 cards in y
2♠ maximum with 3 cards in y
2NT maximum with 2 cards in y


If you are to find a 4-4 heart fit after 1♣-1♠-1NT, you start with Roudi, and then bid 3♥, you can find the new fit at the 3 level, there is no rush for opener to jump.

If 3♥ shows a 2452 or 1453 maximum, I think responder should be delighted to hear this.

2♣ then 3♣ is the normal way to sign-off in 3♣.

If 2♣ includes this hand-type, it's obviously unplayable to allow opener to bypass 3♣ (unless, I suppose, you restrict this action to hands with good club support).

Regarding your main question, most of the people I play with prefer 2-way Checkback.

two way checkback

1d=1s
1nt=?
2c=invite checkback (you can never play in 2c)
2d=game force checkback( you can never play in 2d)
3c or 3d=long minor and weak with 4 spades.
also add:
1minor=2h=5 spades and 4hearts....decent hand but less than invite. has many names including "reverse flannery"

Merry Christmas.

In the version of 2-way checkback that I play, 2♣ is a relay to 2♦, which allows you to play there or show an invitational hand of some sort, so saying that you can never play in 2♦ is not entirely accurate depending on your system.

my understanding is that it is a standard part of classic new minor forcing for opener to jump with max hands

Hi,

For us, 3H denies 3 spades, showes 4 hearts
and a max.
A 2H response would deny 3 spades, showing
4 hearts and a min.

The first hand you gave for responder: you know
diamond will play better, because the partnership
has at most 4 clubs between them, actually the
partnership will have precisly 4 clubs between them,
ignoring the fact, that opener bids 1NT with 4441,
and I am not sure, if you want to play 3NT in this
case.

The 2nd hand you gave: well I would pass 1NT, but
I usually play NMF, but who tells you, that 3C plays
better than 1NT.

With kind regards
Marlowe
