The maniac who barrels three streets on a dry board is bluffing way more than you think. Their range is almost never the nuts. They just can't stop pressing.

Why they do it

Maniacs at $1/$2 are action junkies. They're not running a balanced bluffing strategy - they just genuinely believe aggression wins pots, and they're right often enough against weak players that they keep doing it. Against you, it's a leak you can exploit.

The adjustment

Call them down wider than feels comfortable. Top pair on a dry board is a call-down hand against a maniac. Let them hang themselves. Don't raise unless you're stacking off - raising just ends the action.

What it's worth

A maniac running a 3-barrel bluff on a $200 pot is handing you money if you can just sit on your hands. One correct call-down per session against a maniac is worth $80-150 depending on stack sizes.
