Perfect perfect beat

[reshumate]

1-2 NL, villain raises to 12, I pick up 8s so I call. Two other callers. Board is 7 8 3 rainbow. Villain bets 40, I make it 100, others fold.

Stack sizes preflop were 400 for me, 500 for the villain. Turn comes a 10. I make it 200. Villain thinks FOREVER, almost mucks it, then throws out a huge sigh and calls. River is a J. I put in the rest of my stack.

Villian calls and turns over 99 for a perfect perfect straight. Trying to think if there was anything I could've done differently. Maybe going all-in on the turn might've priced him out, but it would've only been another $90.
