Question:

You deal and open 1. Partner responds 1NT. You might play that as forcing, semi-forcing, or "nothing special". You need to make sure you and partner are on the same page. For our answer, we'll assume semi-forcing which means partner has up to 12 points and we are allowed to pass.

What is your action after 1NT with: 

K109765
AQ32
A2
2

Answer:

2. Always get the other major into the picture when you can. If you had 6-4 with a minimum, a decent major and a so-so minor, it would be okay to repeat your major. For example, with:

KQJ987
A2
J876
2

a 2 rebid would be acceptable.
