$10k WPT Foxwoods - Turn/river line with trips on a dry board

[psyduck]

Background: villain is a mostly straightforward TAG leaning on the tight side. He is one of the better players at the table and seems to be able to hand-read. He opens fairly tightly but also c-bets with a good frequency, almost always heads-up but he has given up some pots 3-way when he was the preflop raiser. He also doesn't value-bet thin at all, opting to showdown in position with middle pair-TK type hands, and some weak top pair hands as well. He also doesn't seem to double-barrel that much, but his flop c-bet frequency in HU pots is fairly high. He probably has some tricks up his sleeve but seems like 95% straightforward.

I have a losing image. I am down from 30k to 20k mostly because of two big hands, one where I double-barrelled on a J [img]/images/graemlins/spade.gif[/img] J T [img]/images/graemlins/spade.gif[/img] Q board and folded on the river (lost T5500 there), and once when I 3-bet AA preflop, and bet/folded on a K 8 5 rainbow board to a massive insta-check-raise-shove (lost T4000 there, and villain saw the AA fold). I am winning all my small pots and losing all my big pots. I have donked into the preflop-raiser a couple times on the flop and have either won or shutdown, and villain is paying attention to this very closely.

Eff stacks 20k, blinds 100/200. Villain opens to T600 exactly in MP at a 9 handed game, folds to me and I call in BB with 7 [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img]. Multiple reasons I called, but let's focus on postflop.

Flop Q 7 6 rainbow (pot 1300). Check, he insta-bets 600, I call fairly quickly.

Turn 7 offsuit (pot 2500). I lead 1200, he makes it 2800 fairly quickly, I call.

River 9 (pot 8100). I count my stack, and see I have like 15500 left. I lead 5200. He asks me to move my hands so he can see my stack, I do so and he sees I have very close to 10k left, and he shoves out all his 5k and 1k chips putting me in after about 1 minute.

Thoughts? I am interested in different turn/river lines, as well as how good this line I took was overall.
