$10.75 NLTRN - TPNK vs. bad villian

[Insane_Steve]

2nd match in a 4 player HU SNG. Villian is a terrible very predictable calling station with the following betting patterns:

-Will call any bet on any "safe" (not monotone) flop with any pair or ace high.
-Will bet pot roughly 90% of the time he bets, with min-bets being the other 10%. The one time I went to showdown when he min-bet, he tabled a busted straight draw.
-If he bets the flop, he will almost always pot the turn, and again pot the river if you call.
-Has not once in the match raised my bets post-flop. He raises about 20% of hands pre-flop (about half min-raise, half 3x) and has never 3-bet. If he raises pre-flop, he almost always pots the flop.

My plan is obviously to pick up one big hand in a raised pot and let him bet or call himself into oblivion, but I've missed pretty much every flop so far in this match.

Also, the match started double-stacked (3,000 chips per player, 10/20 blinds).

Blinds are 20/40

BB: Hero (3,040)

Hero ???

Line check? Ok, so the flop call might be total spew, but against this type of opponent is this hand good enough on the turn/river to take a stand?
