You open 2NT (showing f.i. 20-21)
and opps intervene with a natural bid on 3-level or 4-level.
(without intervention you play Romex).
What system do you play after the intervetion?
DBL takeout?
3Y forcing?

* Dbl is TO.
* A new suit on the 3-level is natural and forcing.
* 4m is non-leaping Michaels (which is on in all situations where we have not shown any suit and opponents have bid on the 2- or 3-level)
* Bidding game is to play.

Note to self: Check with partner is NLM is on with less than 5-5 distribution in situations like 1♠ X 2♠ 4♣, after all we have shown "some" shape.
