8. Stop giving away the strength of your hand.
If someone opens for a raise pre-flop (assume $6 in a $1/$2 no limit cash game)and you are sitting there with AA do not make a small re-raise to $10 or $12. Either make a normal sized raise (to $18 to $24) or even just call. If you think your opponent has a big hand then raise. If you are concerned about playing your AA against multiple opponents then raise. If you want to get tricky and try to trap then just call. Either is a much better choice. The min-raise tells your opponent you have a strong hand and decreases your chance of winning a big hand. I see this mistake all of the time and is one of the easiest to correct. Improve your poker game.
