tournaments in earlier phases

i have a question about your opinions about how to play hand likes describe below

tournament with 150 entrants
chips 3000
the tournament is in the earlier phase, so i dont have any read
blinds 15/30
hero: in the cutoff with Kc Qc
raise to 90
button: call
the blinds fold

FLOP: Kh8h6s
Hero bets 200 (pot-size)
button reraise to 400

how you proceed in this hand?? or how do you play this hand before? I think i'm to passive in this circumstances...

hero: call
TURN: 3d

hero checks
button bet 600
hero calls

RIVER: 4s
hero checks
button bets all-in

i would be very happy for a opinion

I'd probably lose all my money in that hand

A very important piece of information would be the buy-in for this tournament.

I'd usually fold the river

the tournament buy-in was 30$
