99 vs a fishy LRR

How are these line(s) :

Capping the flop and seeing if he checks the turn in which case, i am checking behind and calling a bet on the river. (1.5BB to showdown)

Capping the flop, and calling down if he donks the turn. (2.5BB to showdown)

Calling the flop 3 bet, and proceeding to call down unless some serious paint his the board. (2BB to showdown)

Lately I've noticed weaker players limp/raising preflop with a bunch of random hands (T9s comes to mind), usually its a futile bluff attempt as they pray that by being aggro they can push a better hand out by simply being aggressive on the flop. Its not a bad play on paper, since most people will always put someone who limp/raises PF on a monster hand. Therefore, I am putting villian on two overcards before I am putting him on JJ+. I am hesitant to even consider the chance that he 3 bet PF with a small PP and hit a set.
