Final Pot: 9 BB

No draws came in on the river so I thought getting 9:1 and executing a free card play on the turn, I had a call here.

Hand 2:
I was new to this table so no established reads.

Hero does what?

I probably have the best hand on the river but having the best hand if called is the real dilemma. Betting into an Ace is even EV or -EV. Betting into a 5x is -EV.

I think a check/call can pick off bluff attempts from missed draws enough times to make it the superior play.
