Those are precisely the blinds im talking about. There you can raise w/ KQ and it is profitable. At 50/1 to 2/4 it is an entirely diff story.

With respect to what I raise with, I will raise w/ anything. I raise w/ AQ pretty frequently, but not always. I will also occasionally limp w/ AK. On the other hand, I will raise w/ a variety of other hands like 66 - AA and a lot of suited connectors. You can build a loose image faster by raising w 24os and then buying a pot and showing than by raising w/ a variety of face cards, trust me.

Overall, I have found it tremendously more profitable to play aggressive post flop as compared to preflop. If you are thinking about moving up levels, take this advice! Usually, when you raise preflop and then c-bet, players are just thinking about ways that that hand DIDNT hit your hand and they are trying to put you on a c-bet. On the contrary, when you call a bet and then bluff, players are trying to see how the hand did hit you. This wasnt true about a year and a half ago and still isnt true at some of the lower levels, but is becoming more prevalent. Players are just wising up to the raise and c-bet (which actually helps when you do hit your hand and makes it more profitable to avoid slow playing and represent a buy).

I've actually found it to be more profitable to raise. Check and then raise huge on the turn representing a slow play. This is the "new" c-bet. Sure you are vulnerable to the extra card, but you are representing a tremendously stronger hand than the regular c-bet.
