Think u played correctly all the way. And call the river bet. He knows it´s a scary card for u and may attempt a bluff with Tx or something else. Raise is too dangerous, risking two bets to win one. There are many hands that beats u.

Think u should bet the flop. If u don´t they might get suspicious since a pf raiser typically raise a ragged board like this.

Impossible to put him on a hand I think. He doesn´t have the odds to draw to a gut-shot, but at this level, who cares?
