Pwned by Freddie Deeb, WPT Bellagio ME

On the first hand I would have played it completely differently. I would have not checked to let Freddy see the turn for free. I would have made a 3/4 pot bet on the flop. If I played the hand like you I would have tossed the first hand after the river since I had no hearts.
The second hand after Freddy bets 5k, I would have pushed all in on him. What could he possibly have, top pair, a higher pocket pair, or maybe he caught the queen on the turn for his Ace Queen hand?
