I am winning, and it's because I play tight-aggressive. You can say it doesn't sound like a winning strategy, but when you look at the whole strategy, like stealing blinds to keep up with the rake, and then the table plays their loose game, and they don't expect it: when you come in with a 4-bet 2.5x the 3-bet. It's a bluffy looking bet, so it's easier to get paid off if the table is loose.
It's actually understanding what a winning percentage is in terms of the actual cards. Aiming for 24% variance instead of a 65%-35% situation like draws usually have that big of a disadvantage on the flop against top set.
