$1/$2 L08 3-handed

[yellowjack]

I've been playing very lag in $1/$2 HORSE on stars, and we're on 08.

I raise Th 8s Js Jh on the button, SB 3-bets, BB folds, I call.

Flop is Tc 2s 4h giving me just top pair, no low.
SB bets, I raise, SB calls.

Turn is 8d, giving me top two with a low now possible.
SB checks, I bet, SB check-raises, I call.

River is 7d.
SB bets, I call.

SB shows 9s Jc As Ac for the straight and scoops.

1) Does my flop raise suck? I wanted to buy a free card and bet if I improved.

2) Is SB's turn c/r terrible? We're fairly unknown to each other so this is for sure not metagame.
