NL50 6 handed

[Go_Blue88]

No reads, just got to the table hoping to alleviate some boredom of studying.

Villian has 38, hero covers

Villian calls on the button, Hero calls in the sb with 77, bb checks

Dealing Flop 7c, Ts, 7s
Hero checks, Villian bets 1.40, bb folds, hero calls.

Turn: 10

Hero checks, Villian checks

River: Hero? Push or lead out? I'm 90% sure villian has a 10.

Edit--whoops, by lead out I meant value bet (which would be about 4 bucks).
