Villain is a tough, tricky, aggressive player. He certainly isn't afraid to make big bluffs, although in this HU session he has been less aggressive and hasn't splashed around in as many pots as usual.

We have a lot of history together HU. Specifically, he loves checking big hands to me on the river. I have paid him off a couple times when he has made big c/r on the river, but I have never caught him bluffing when he takes that river line.

I'm not really interested in any street but the river, but feel free to comment on other streets.

Effective stacks are $16500

I raise to 150 PF w/ T4hh, he flats. (300)

Flop is 9h 6c 5h

He checks, I lead for 250, he makes it 750, I make it 2050, he calls. (4400)

Turn 6h, putting the 3 flush out. It goes check check.

River is the Ac. He checks quickly, I think for about 20 seconds and then bet 3400. He thinks for about 40 seconds until his time bank starts to run and then makes it 12400, leaving himself about 1700.

Call or fold?
