Turn semibluff, time to fire 2nd barrel on river? 5 10

[KINGOFINLAND]

In previous hand I folded to villains mini check-raise on turn in a relatively big pot, villain seems to be agressive side, no better read since this is the first time I'm playing against him.

Villains stack is 2k and I cover.
