Value betting with awkward stack sizes (100NL 6-max)

[stickdude]

I've been at the table a little while now, and villain seems call-stationy from what I've seen so far.

6 players
Converted at

Stacks:
UTG ($153.75)
UTG 1 ($75.35)
Hero ($99.00)
BTN ($112.75)
SB ($43.55)
BB ($6.50)

Pre-flop: ($1.5, 6 players) Hero is CO [Ah]
1 fold, UTG 1 raises to $2, Hero raises to $6.5, 2 folds, BB goes all-in $6.5, UTG 1 calls $4.5

Flop: [Ad][8h] ($20, 3 players)
UTG 1 checks, Hero bets $14, UTG 1 calls $14

Turn: ($48, 3 players)
UTG 1 checks, Hero bets ?????

The problem here is that villain has a little over 1 PSB left on a drawy board. Even a "normal" 2/3 PSB is almost all his chips. A smaller turn bet would let him call (if he's drawing) and either fold the rivers he misses or double up the times he hits (since I can't fold to a river "shove").

Would it be better to just go ahead and put him all-in now?
