I "attempt" to open up a bit more in LP and steal blinds more with hands like A8o, K9s, JT etc...

I dont open up much from EP or MP though. I'm just not good enough yet to tell when I am ahead or behind since their range is still very wide on the flop and a hand like AT from EP is not fun for me to play. Unless the board is T high I dont have a lot of confidence putting money in the pot.
The other change i made was I open raised with all PP. Sometimes I will limp in with 66< to hit a set vs maniacs but I had the table fold almost every time when I raised with them...

I also reduce my 3betting (which isnt that high to begin with) b/c I find that when they were raising preflop, it was with very strong holdings so a 3bet would only really be a bluff.

It was a tough grind yesterday...I have a couple hands that I should put up here...one where I had QQ and I folded on the flop to a weak/tight player who all of a sudden found his balls and bet with a J high board. So I figured the only hand I beat was AK but since there was no A or K on the board so I didnt think the pansy would cbet that strong on a board he completely missed. It was a clear value bet by him. He probably had JJ+ and I was crushed but I cant be sure. That hand bugged me all night.
