In our partnership, we have agreed to combine xyz and Walsh and therefore are able to show game force or invitational hands after a 1c:1d bid. Does this mean responder with 4 diamonds and a 4 card major can bid up the line with 4 diamonds, as can later invite with 2c? Thanks for your help.

I think 2c followed by 2M shows five diamonds so opener will correct to 3d with a doubleton in the major.

NO

You always start with the major when 4Major and 4 diamonds. You do this with all hands of any strength.

That means if you start with 1d and have a 4 card major you 100% promise a 5 card diamond suit and game force values.


A simple example:

1c=1d
1h=1s

opener has shown 5c and 4h
responder has shown 5d and 4s and gf values.

another example:
1c=1d
1s=2h

opener has shown 5c and 4s
responder has shown 5d and 4h and gf values.

to repeat responder with 4d and 4 major and any strength you start with the major and skip over the d suit.

We have those agreements, plus one more ---which might make us a minority-of-one pair:

1C-1D
1H-2H. Those who dislike this addition to the G.F. array have good points, but their objections don't seem to come up at the table. With the hands of less than G.F., 3-card heart support, less than 3 clubs, less than six diamonds --- AND three bad spades, we are willing to rebid NT as responder. If the opponents hold ten Spades, someone won't be letting us play NT.

xyz and walsh allow for all sorts of undiscussed auctions.

1c=1d
1h=2c
2d=2h

opener has shown 5c and 4h
responder has shown 4+d
2c then 2h by responder is invite but responder has denied 4h. Keep in mind with 4h and invite or less hand responder starts with 1h, you skip over the longer d suit.

Perhaps the hands are something close to:
xxx...Axxx...x...AKxxx
Qxx...Kxx...AKxxxx....x


1c=1d
1h=2h is gf with 5d and 4h.
