99 on the button $5/$10 full table

[Paluka]

Folded to me on the button with 99. I make it $30 both blinds calls. Sb has about $600 left, bb has $1000 and I have both covered. Both players were new to me but had seen few flops so far.

Flop 456 rainbow. sb checks, bb bets $75, I call, sb folds.

Turn 2h putting 2 hearts on board. BB checks, I bet $175, he calls.

River Tc. bb checks. Seems like my options here are a) check or b) try a small value bet.

I'm pretty new to no-limit, so I was having hard time putting this guy on a hand. It felt like A6/77/67 to me.
