At a table with two or more maniacs, the correct adjustment is to tighten your opening range and widen your calling range. The opposite of what most players do.

Why they do it

Most $1/$2 players respond to maniacs by either spewing back at them or tightening up completely and not getting paid. The correct response is in between - play fewer but stronger hands preflop, and then call them down more often postflop. Let the table chaos work for you instead of getting swept up in it.

The adjustment

Open tighter. Call 3-bets with strong hands instead of 4-betting light. Postflop, call down wider with made hands. You don't need to generate your own action - the table is generating it for you.

What it's worth

Adjusting correctly to a chaotic table instead of matching the energy saves $100-200 in EV per session and puts you in more favorable spots when you do play big pots.
