A6s line check

Party 3/6

Villian is 25/14/2 after 50 hands. The only hands I've really seen him show down were a few hands where he called flop bets with overcards and donked the turn/river when he hit a pair. Once he gets involved in a pot postflop, he doesn't like to fold.

Flop

I donk, he raises, Hero??

What is the best plan:

1.)3 bet and let the hand play itself.
2.)Call and donk/3bet the turn.
3.)Call and checkraise the turn.
4.)A different line entirely, involving some kind of flop check...


Thanks
