2/5 Live NL I love playing big pots with 1 pair

[JustPlayingSmart]

I was at the Winstar casino 1 mile north of the Texas border on Friday and sat in 1 of 4 2/5 NL games (buyin of $500). About 2 orbits in, I had played basically 0 hands. I wouldn't normally be that tight in a passive game like it was, but I was getting hands like J3o, so I didn't even have anything worth limping in position.

I usually raise 50% or so of hands that I would play when I'm on the button, and I raised a couple limpers to $25 with AQd. Only the big blind called. He was about my age (around 25 or so) and wearing sunglasses. I didn't know if he was good or not, but he certainly at least thought he was good, judging from the way he was talking to the guy next to him. When he called, I was pretty sure it was with the intention to outplay my "obvious" overpair.

The flop came T96 with 1 diamond. He bet $30 into a $60 pot, and I raised to 100. He called. The turn was a 7 and we both checked. The river was a Q and he moved in (I had $350 left, and he had me covered by $100 or so). I tanked for 3 minutes and called.
