Yaw control in a tandem rotor helo?

I've been working with a conventionally configured helicopter for a
few months and this suddenly started eating my brain.

In a 2 rotor helicopter you are countering the torque of one rotor
with the other rotor. But how do you do a pedal turn? In a coaxial
I'd think you'd increase the pitch of once set of blades and decrease
the other. But what do you do in a tandem, like a CH-46? Increase
the pitch, you get more torque, but you also get more lift, so the
aircraft would move forward or backward -

Any helo pilots out there that can set me straight?

Increase pitch for the portion of the rotation that the direction of blade
travel would "drag" the assembly sideways.

But what about the resulting left from the increased pitch? Wouldn't
that cause quitee noticable roll?
