NL500: QQ on KJ967r board 3bet pot OOP

[Janis N.]

Hero is MP with Q[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/heart.gif[/img], $515 and TAG image.

CO is 19/16 TAG and covers; he's 3bet KQs from the blinds before against my BTN raise but we have no extensive history.

UTG folds, hero raises to $17.50, CO raises to $60, 2 folds, hero calls $42.50.

Flop K[img]/images/graemlins/diamond.gif[/img] J[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/heart.gif[/img] ($127.5)

2 checks

Turn 6[img]/images/graemlins/spade.gif[/img] ($127.5)

Hero bets $90, CO calls $90.

River: 7[img]/images/graemlins/diamond.gif[/img] ($307.5)

Hero checks, CO bets $90, Hero calls $90.

I think my turn bet is bad as he doesn't have AQ/TT/air often enough there, but it's hard to avoid betting when people check. Is river "meh, I call" or not really?

Edit - actually regret posting it as turn is a c/f or c/c and if c/c we eval river, idk.
