1NT-(2♣ Landy for Majors)-DBL
We play this DBL as wanting to penalize opps in one of the two majors. Next all DBLs are penalty.

Question:
(2♣ weak with both Majors)-DBL
We also play this DBL as wanting to penalize opps in one of the two majors.
But does this work?
In the 1NT case both opps have showed strength, but after opps open 2C then partner can still be very weak.

1)
(2♣ weak with both Majors)-DBL-(2H/2S)-DBL
Should this last DBL be PEN or Takeout (takeout to allow partner to show some strength)

2)
(2♣ weak with both Majors)-DBL-(2H/2S)-Pass
(Pass)-??
If DBL by partner would have been penalty then maybe partner passed with some points but no good bid?
