NL50: Flopped bottom set, get turn c/r by the initial raiser

[Gobias Ind.]

So yeah, worst month I've had playing poker. Trying to plug leaks. Is this call spew or just more variance?

Besides raise flop, anyone else play it differently? No reads on villian. Obviously in my mind, I know there's a distinct possibility I'm beat. . is an inability to fold sets a leak?
