Interestingly, that’s pretty much my strategy. Well, in that I tend to check/raise l when I hold those cards and then get more (or less) aggressive as the hand plays out. I try to take into account the style of the other players as well.
I’m coming up on a personal milestone- $500k in the bank soon (ring game winnings and daily bonuses only- I’m intimidated by tournaments- and unless I blow it all tonight). I made a bunch of stupid mistakes the first couple of months I started playing- chasing impossible hands, stupid bluffs, etc- but now I win more than I lose due to figuring out the style of play you describe.
