Tactics against 3N-3W-3N-1

-MC-MC-MC-
-DML-DMC-DMR-
-DC-DC-DC-

Any ideas how to play against this formation? (which formation, tactis, etc.)

3n-1-4-2 with flanking and red arrows on ml/mr did not work :O

3-5-2 should work. The DMC is useless bc he doesn't have an AMC.

Yup! your opponent is full defensive, so you should press them! 3n-1-4-2 is not good option, you need more offensive. Like 3-5-2 v-style or maybe 4-4-2.
