99 in Blind battle

33$
Blinds 200/400 i have about 20k and villain as well.

He completes, i raise to 1600, he calls.

Flop 853r he leads out 2400, i call
Turn: 4 he bets 4k, i call
River K he checks, i bet 5k, he calls


My question is: would u raise the flop?
Would u valuebet the river?

I pretty much put him on a 8 or a small pp, i think he would not check king on the river.
