Villain unknown.
These spots are so tricky for me. I believe every time villain (in that case a fish) trys to bluff me out.
OTF and OTT my thought was not to raise to keep Ax and over pairs in the pot.
River I though maybe slow played AA, KK, AQ or missed flush AcKc. . QQ, A2, 44 and 55 have me beat.
