Light 2/1 Style - Frances And Others - 1M-2x-2M NF

[Finch]

What about this sequence?

 

1♥ 2♦ 3♦ 3♥

 

And another one:

 

1♥ 2♦ 2♥ 2NT

 

or:

 

1♥ 2♣ 2♦ 2NT

These are easy. They are all non-forcing, invitational.

 

The first because this is the way you show a 3-card invite.

The second and third because this is the way you show a raise to 2NT. (If you are playing really basic Acol you might have responded 2NT with a raise to 2NT but we don't play that.)
