Maniacs are not smart enough to play good and bad hands fast.

They raise / re-raise with trash, and check the nuts. If I'm re-raised huge by a maniac I'm considering QQ the best hand all day long and putting my stack on the line.

The usually tight/weak 25nl cash player though would never re-raise/Push without AA/KK/QQ so most of the time you are pretty safe to fold in that spot.

This question is so much about the player you are playing agaisn't..
