The river had me in 2 minds. His bet is really strong to me, I raised pf and bet flop which means I could easily have an A and I notice players at this level tend to think you always have the Ace so that shows a lot of strength to me.

On the other hand I played very weakly after the flop and it looks like I don't have much so maybe betting lower and missed draw. I realise I am sort of contradicting myself from above but all these variables made decision somewhat tricky in my mind

So call or not?
