RFI% is the % of times you raised when you were the 1st to enter the pot. Therefore, if somebody limped before you, you were not the 1st to enter the pot. It doesn't mean much to me...my AK RFI% is 37% but who cares?

I currently play at $50nl, 27k hands and AKos is also my 4th most profitable hand behind AA, KK and QQ. I play it as follows: Raise or Re-raise pf in any position. However, I will just call a re-raise if villain is a rock (3% pf raise or less) and hope to spike a K or A on the flop. I will take villain all-in pf if I am sure he doesn't have AA or KK. I always bet the flop hard (like I have AA) unless I am OOP and there are more than 2 callers in which case I will check if I miss the flop. I also raise 6xBB pf which seems to announce "I got AA" to the world. If I miss the flop and my c-bet gets called I will re-eval the turn and will likely check/fold if I am OOP but will continue betting if checked to me in position. The bottom line is that the way I play AK fits perfectly into my image...I am 15/7 TAG. Lastly, I would not recommend that everyojne play it this way....it works for me because of my table image. Since I am a fairly profitable player and have been playing the same site for all 27k of my hands, I tend to beleive that there are a ton of villains out there who probably have a "stay away" note on me. I tend to showdown only premium hands (57% W%SD) so I have no reason to beleive that many of the regulars out there want to mess much with me. In short, when I play AK like AA, villain beleives it and will fold the majority of times to my c-bet on the flop if it even gets that far. If you are loose and splash around in a lot of pots, you will get played back at much more than I do and therefore playing AK this way won't work well. The bottom line is that you need to play it in a way which suits your overall style to maximize profits. No one way is the best.
