My partner (a strong player but new to KS) is concerned about responding to a 1m opening on certain balanced 9 counts.
If opener is balanced and...
... opens 1C:
- when responder holds =3334, it begins 1C-2C-2N...
... opens 1D:
- when responder holds =3343, it begins 1D-2D-2N...
- when responder holds =3334 or =xxx5, it begins 1D-2C-2N...
Responder can't pass 2N, opener may have up to 19. With these flat shapes, there's no sensible m-suit rebid, so it appears we've endplayed ourselves into 3NT. This may put us in 3N on a combined 24... against the field at matchpoints and pretty aggressive even at IMPs.
Has this been a problem for your KS partnerships? How do you manage this?
