a new line for me w/ the 3'rd nuts

[TxRedMan]

villain is laggish, and a winner in the game to the best of my knowledge. he views me as tight and probably a little on the weak side although i've just been card dead for the 20 or so hours we've played together. ive never gotten out of line, but he has a few times. i think its pretty apparent to him at this point i'm not going to play a huge pot without a nut hand.

i get moved from the must move to the main game, and i've never played with UTG+1 before so I limp 10-10 after he limps UTG+1. Villain limps in UTG+2. Stacks are $1700.

Flop

J-10-7 rb

UTG+1 bets $35, I call, Villain calls, blinds fold.

Turn

7

UTG+1 checks, I bet $50, villain raises to $175, UTG+1 folds, I call.

River

4

I lead for $400.

I wanted to make a bet that a seven would have to pay off. It felt like my hand was pretty transparent, and I felt like the majority of his range was a naked seven, so after I call the turn I cant see him betting for value on the river.

Thoughts?
