Villain is unknown.
It seems a clear push on the river but it is?
If we push he will call and win with AA, KK, AK, K5 but I'm not sure he would call with a flush or Kx here.
Our check/push otr would be super strong. bet, check/call, check/push
I would just call the river because I can't see value from worst hands.
I'm gonna show the result later
