Party Poker 6 handed $200 NL

Villain is been trying all types of tricky moves and has donked off about $500 of his $700 stack when i sat down.

Villain ($332.20)
Hero ($358.85)
Button ($286.40)
SB ($198)
BB ($124.80)
UTG ($291.75)

Preflop: Hero is CO with Ad, Ac.
UTG folds, UTG +1 folds, Villain calls, Hero raises to $8, folds to BB who calls.

Flop: ($27) 6s, 7s, 8d (3 players)
BB checks, Villain checks, Hero bets $22, BB folds, Villain calls.

Turn: ($71) 7c (2 players)
Villain bets $40, Hero raises to $100, Villain calls.

River: ($271) 2s (2 players)
Villain bets $220 (All-In), Hero? What can I do here with $200+ still behind?

Just call turn for sure. The river probably plays different if you just call. I'm probably folding that river but it's hard to say with your given read (tricky, but also a donk).

Ya, I mean I would love to call and bust him, but his line seems like some sort of flush draw but he's so dumb he could have been after a str8......real tough spot with AA
