In casino, I've seen people do this also. When I sat next to this guy, I asked the guy that he could've just checked and just fold when others bet. His reasoning for doing it was "I don't wanna catch something in the future and cost me anything." I just told him "oh, right. you got a point there. I never thought about how much I've lost from future streets." just to keep things social and not make him feel like I'm questioning his play but at the same time, I was curious why people did this.
I personally disagree with this because if someone makes a bet and others are faced with the decision to whether call or raise, I like to put slight pressure on them that I'm still left to act and that I'm capable of check-raising and possibly squeeze because I've done it so many times. But if I just fold rather than check/fold anytime I don't have a hand on the flop, then they can have comfortable decision since they don't have to worry about me.
Another thing is, whenever I just fold if I dont' have anything from big blind but when I don't fold, then people can instant narrow range of hands on me since people will assume I would've folded if I had complete rags from big blind that's been checked around.
But that's just me.
