Ok thanks guys, its quiet clear now.
When playing i felt that there was a lots of stabbing going on as everybody folds too much these days at zoom.
I thought BB is just giving it a go after Button checked the flop and he might give up without much thought to a c/r - this however was not the ideal spot to do so.
Going through a downswing and getting to a point where I question even the most basic plays so thanks for the feedback, I appreciate it...
