No stats, no reads. Not entirely sure what to make of villain's turn raise here, but it represents a stronger hand than mine. I'd expect villain to raise sets and at least top 2pair on the flop on such a wet board, but it's not inconceivable with all the FPS that goes on that he could wait until the turn to raise sets. AJ and J9s are obv real possibilities here. Against those I could justify flatting to try and pair the board. However, the danger is that if he's got a better two pair or (somehow) KK that he played tricky pre, I'm drawing dead and the board pairing could felt me. Sigh/fold seems like the best play to me here.
