I get fancy and play bad

[turnipmonster]

long time, no hand. the converter is weird/broken now, eh? anyways, villian in this hand is a pretty big donkey, and the table is very loose and aggro.

5-10 6 max, I'm (2k) in the bb with AhKd. villian (2k), opens for 30 in MP. folded to me and I call.

65 in the pot, and the flop is Ks 4s 5c. I bet 50, villian calls.

turn is 9c. I check, villian bets 120, I make it 400 straight, villian goes and gets a beer, watches a movie then finally calls.

the river is a Ts. there is 965 in the pot and we both have ~1500 left. what's my plan for this card?
