question on this hand

[slowbutwilling]

$300 max buyin 6 players. hero bb with AC 10C Sb decent player that likes to make moves and will carry them all the way but can lay a hand down also. Button total moron who calls down with A high and bottom pair quite often.
Hero $595
SB $750
Button $135
$2 $5 blinds
Button calls, SB raises to $25 I call button calls
Flop JC 8C 4D
SB checks I check button bets $55 Sb Raises to $110
I think for sure button will call So I call Button folds
Pot now $350
turn 6H
Sb bets $110 I call
River 7c
sb bets $50 I raise to $150 Sb calls and announces 2 pair J8

Not sure of my play in this hand, but was not sure if it was a move on flop to get heads up with moron or if it was a strong hand. SB turn bet just pulled me in.
