Only have 30 hands on the villain, for those he is 37/7/3.3.

Table was fairly loose passive, thought I could limp here without being raised, so I call preflop with JTs, 3 others are in the pot.

-Flop comes 6TT, two checks and I bet ~1/2 pot, one call and two folds.
-Turn brings a 7, I bet again about half the pot, villain minraises, I call.
-River brings a 5, I make a small bet that I can call without committing too much if minraised, about 1/3 of the pot. He minraises and I call.

This is a standard WA/WB situation, Im just not sure how I should handle it. Should I have just checked the flop? What about my turn and river bets?

What type of line would be considerend "standard" against a fairly unknown villain?
