HU HH -- what's my play on the turn?

[the shadow]

The original thread was on what's my flop play with TPTK.

Here's the hand so far:

# 29
Round II, Level II (30/60)
Seat 1: 2nd villian (3855 in chips)
Seat 2: hero (2145 in chips)
2nd villian: posts small blind 30
hero: posts big blind 60
*** HOLE CARDS ***
Dealt to hero [7c Ah]
2nd villian: calls 30
hero: raises 120 to 180
2nd villian: calls 120
*** FLOP *** [6d 5s 7d]
hero: ?

The median vote so far is to bet between 2/3 and 3/4 the pot, with betting 2/3 the pot getting the most votes.

I bet 300, about 80% of the 360 pot and villian called:

*** FLOP *** [6d 5s 7d]
hero: bets 300
2nd villian: calls 300
*** TURN *** [6d 5s 7d] [9s]
hero: ?

What's my play on the turn and why?
