Fire out or check?

[Jim T]

Early in a MTT. I have about average # of chips at 1500. Villian has me covered by a few hundred and he has just been seated so no reads. I have 99 in MP, no spades. UTG calls 30, UTG+1 (Villian) bets 150. It's folded to me, and I call. Everyone else folds so it's heads up.

The flop is K56 rainbow. Villian checks and I bet 210. He calls.

Turn brings a 7, now 2 spades on the board. He checks. Should I take another stab at the pot or take the free river card to see if I hit one of my 6 outs (hoping that the spades are good)?

I would check here, Your hand just improved ( giving you more outs), and he obviously likes his hand to call the flop with no real draws. Plus your stack is getting a little small to bleed it off here.
