Hello, guys!
Preflop was pretty standard 3bet and also I guess the cbet was ok, but when the villain reraised me I wasnt sure what is the best play. He was opening very wide preflop so I was afraid of sets and two pairs (what he actually had), but on other side - I thought he could have had straight draw and he is just trying to steal the pot or maybe hand like AT which would be good for me. Also the SPR was low and it means I was too deep involved in the hand so I decided to call. Correct me if I am wrong. 
Also I would like to know about Cbet size. Was it okay or it could be a smaller or a bigger?
