Feedback appreciated on this hand

I would appreciate any feedback on this hand. (I am sorry I do not have the official hand history, but it is duplicated below).

About 2 hours into a 150 player $200 buyin in tourney on line. 50 players left. Top 20 pay.

I have about 7,000 chips -- good enough for 11th at the time. Villian in this hand has me covered with about 11,000 chips. Blinds are 100/200.

I am in BB with KK. Villian is UTG+1.

Villian raises to 600.

Folded to me in BB with my KK. I raise to 2000.

Villain thinks for a while and calls. Pot is now 4100.

Flop comes A-8-4 rainbow.

I check. Villian checks.

Flop comes another ace.

I check. Villian bets 2000.

Your move??

Also, I would appreciate any criticism/feedback on the other streets.

Thanks!

depends on if you want to gamble here.

you showed weakness on the flop and the turn.
so he can basically put you on a big pair and be running a bluff here.

it is really kind of player dependent...
