Villain is basically unknown. 23 hands, 26/17/0

Preflop is standard and the board is pretty dry so I choose a rather smallish cbet sizing.
After his call he might have Tx, 9x, low pairs and straight draws and seldom some random floats like Ax or KQ.
The turn gives me showdown value and kills action for his draws so I check with the intention of calling the river depending on his bet size.
On the river he checks again and I hit the Q, so i decided to go for value against his small pairs and other Ax.
After his x/r I fold because I dont see him doing this with anything worse than Tx, 9x or KJ.

Makes sense?
