Dealt to Hero A A

fold, fold, Hero raises to $0.75, fold, fold, fold, fold, SB calls $0.65, fold

FLOP ($1.75) T 5 7

SB checks, Hero bets $1.25, SB raises to $3, Hero calls $1.75
Hero bets the flop for value from lower PPs, 1 pair hands and flush and straight draws. Hero hates the almost minraise. I decide to call because the flop is fairly wet. There are plenty of potential draws but the bet size makes me nervous. It doesn't look like he really wants a fold.

TURN ($7.75) T 5 7 4

SB bets $6, Hero calls $6
86 go there. Nothing else really changed. Nervous call.

RIVER ($19.75) T 5 7 4 J

SB checks, ?????

OK now 86 and 98 got there, but villain checks to us. What's our best plan? I was trying to get to a cheap showdown. So, check follows that plan. However, is that giving up value? Can we get calls from hands like AT, QQ, KK? Would he really trap here when I haven't shown any aggression after the flop? I'm an unknown to him too. So, he can't have much reason to think I'd bet here. The check just throws me off here.

I'd check river. I'm pretty sure you are beat here and villain is too scared to value bet. I'd strongly consider folding the turn cause his line does reap strength.
