bad river spot vs maniac AQs 5/10

[bottomset]

SB is a 55/35 LAG
BTN is 47/10

couple hands earlier SB donked into me with 2ndpair weak kicker, but slowed down after being raised on the flop.

BTN seemed to make loose flop calls, but folded a lot of turns and rivers

so I have the feeling this turn c/r is a big hand most of the time, but getting 15/1 on the river means I only need the best hand ~7% of the time

good flop raise?
turn bet?
