10/20 Standard?

[Drontier]

This is standard for me? But that may be a huge leak.

I am in the bb with Ac7s

Folded to button who raises(less than 25 hands on button, but ive seen him raise in LP with 1 or 2 less than premium hands. I call

Flop Js3s3c
check, bet, call

Turn 4c
check, bet, call

River Jd
check, bet, call

If flop was slightly different so it was unpaired what do you do? What if river didnt pair the the jacks? Is my line the best? This hands make me feel lost sometimes.
