First, 6 people saw that turn so someone will have a straight more than 50% of the time. Making multiple pot bets without one here is suicide.

You already represented a made straight and he called and now he's betting into you. There are only 3 possabilities : he has a 10 straight, a 9 straight, or he's an idiot (or perhaps a genius who has somehow put you on a 9 straight).

If my math is correct there's about $9 in the pot when villain wakes up and pots it.

Ignoring the last one for now, there are 9 ways he could have you tied and 12 he could have you beat. Therefore, a call nets you $4.5 9 times and costs $9 12 times for an average of just over $3. Now, if you have him beat you win $18. This means that he needs to be bluffing here more than 20% of the time to make a call an winning play. That's very high for this board at these stakes at Pokerstars where I play.

Now let's say he folds the 9 straight if you raise $X back and re-pots with the ten straight.

Your raise wins you $18 9 times out of 21 and costs you X 12 times out of 21. To break even you need to bet $18*9/21 = $7.71 or less. This isn't enough to qualify as call, much less a raise.

Unless you have a good (make that very good) reason to believe he has a set or less this is a clear fold.
