Line Check

Do you guys feel i played this hand ok? Everyone's feedback is welcome.
No reads on this guy, I've only been at the table for 20 minutes. Would you push the river? If so, would it get called? Assume the other guy is fairly good/decent.
Results in white.

BANKROLL100K balance $213.20, lost $190 [ Kc Kd ] [ two pairs, kings and nines -- Kc,Kd,9s,9h,7c ]

I'd make it ~$60 to go preflop. I also check behind on the river.

Raise more pre flop, the rest seems fine.
