WSOP limit tourney, Hero has QQ in CO, blinds are $300-$600, limits are $600-$1200.
Hero's stack is maybe 17K, which is a but above average, but the blinds are going up pretty quickly so every chip is getting precious.
Villian just got moved from another table wth a similar stack size and was forced to post BB, so no read but looks like a newbie.

Hero raises first in to $1200 in the CO with , everyone folds including SB, villian calls.
Flop:
Villian checks, hero bets $600, villian checkraises to $1200, hero three-bets to $1800, villian four-bets to $2400, hero calls.
Turn:
Villian leads $1200, hero calls.
River:
Villian leads $1200, hero????
What does villian have, and did he play it correctly?

Critique each street.

The only thing that bothers me here is that he isn't afraid of the King. Not knowing anything about the opponent hurts. You could assume that he doesn't have you on a hand nearly as strong as QQ in a steal situation. He could be betting any pocket pair at this point like this up till the river, but again, him showing no fear of the King on the river is strange. What could he expect to be ahead of there with a PP? AQ/AT? There's too much in the pot now though. What are you getting? 9 to 1? I think you have to call here.
