Update 
Just played a quick session on nl5, like 300 hands, it's not even a sample I know lol, but came into few interesting spots and would like to discuss it with someone if they feel like it.

The thing is, I knew I was behind with that hand on that flop most of the time, I still opted to cbet because for all I know, opponent may not have A there or any straight-draw.. When he called it, I was ready to give up, but then I saw he has like 0.87$ left and I decided to be ready to bet/call just because of that.. Probably the most stupid reasoning, but it's late right now to change anything.. 
And, am I giving up too easily in this spots? :/

But I also think 3bet stat is flawed in previous examples, because HEM2 now shows that 3bet stats after those hands have happened.. :/
Hope to get someone's opinion..
