Final Pot: $50.35

How do we play the turn, lead out again, give up, c/c, I thought check raise got rid of weak combo/bluff?

Since he already has ~60% of his stack in I don't think you can get him off his hand with the check raise.

Against an unknown player I bet/ call his push..

In 3bet pots, it is fine to cbet less of a percentage of pot. But, on a monotone board such as this, I cbet little closer to size of the pot.

On turn, we arent giving up and we dont wanna give a free shot at a heart. A psb is close to rest of effective stacks, so I would just open shove.
