3. Deciding that my image credits me far more then my hand, not realizing that my opponent has noe clue about image.

This one is a killer if you combine it with the following:

#2.) Long, drawn-out, elaborate bluffs that almost never work. Sometimes I get attached, and I can't let go, I'll c-bet, then plug the turn with nothing, then there's so much in the potby the river that I try "one more", and it costs me a huge pot or my tournament.

#5.) Raising small bets with nothing.. you know the weird 20% of the pot bets that people make online.. I've found more often than not they want you to call and they just don't know what they're doing.

Then this last one I do... even though they often are just bluffing it can be costly to find out.
