25/50NL Hows My Line?

[Mad Genius1]

Heads-up, villian has about 6k I have him covered. We have been playing heads-up for about 30minutes since game broke, he is solid, not too creative, and I have been bullying him quite a bit. We've only gone to showdown a few times on significant pots and I've had the goods usually.

74s in BB, he raises to 150, I call. He was raising probably about 40% of hands, sometimes minraise, other times pot-raise. I defended a good % of times.

Flop 335r. I check, he pots it for 300, I make it 900. He continuation bet about 50% of time after raising pf, I would fold most of the time OOP. THis is only my third or fourth flop cr and first time I haven't had the goods.

He calls the raise. Turn is offsuit 4. I bet 1000. He calls. Rirver 3, I move in for his last 4k..

Will I make him fold his PP enough times on the river for my bet to be +EV, given the circumstances? We have no prior history with each other before this session, fwiw.
