#1 isn't horrible if you have an expectiation of it getting raised behind you. I've even limped in CO before when both the button and SB were VERY aggressive. (Raising any pair and any 2 face cards type of aggression. One guy was good and used his reading skills to bluff at most pots, the other guy sucks.)

#2 I absolutely hate. The ONE advantage of it is that you MIGHT get a hand like J 10 to fold - if they're solid. No point. A useless play...Unless you plan on tabling your 99 and later c/r with top set.... hate this line.

#3 I'll make this play live at a weak table when I'm confident of my reads. Any crazies, any loosies calling down 2nd and 3rd pair, any TAGs who will C/R or bet out draws heavily - this move is HIGHLY -EV. ...but I don't abuse my button privelages even so...people get suspicious quickly. Besides those table conditions being right, I'll usually NOT make this play - though still may on occasion later in tourneys if I have the table image to accompany.
