$50 FR - blind battle grows into large pot

[MadMat]

Not my usual play in this position, BUT, villan is very LAGgy, 54/20/6.5 over 50 hands, and has been 3-betting preflop very liberally, especially against my late position raises.
Did I pick the right spot to play back against a maniac here?

Yes.
Some people will tell you to wait for a better spot, but this looks good to me.
He is definitely looking for fold equity here.
