Quick question

[TMFS9]

Lets say 20/40+ game, villan is a your typical 40/25 lag that can read hands but is not overall very good. He raises in MP and only you call in the bb with 57s.

The flop comes A 5 7

What is your line against a villan who will go multiple bets on flop and turn with top pair and good kicker, would probably call down with an overpair to the 7's, and fold any other hand either on flop or to a turn bet but might bluff the turn if you just called the flop.
