1) Value bet/raise really wide. If you have a pair (of anythings) its usually worth sticking some bets in.
2) Recognize when they aren't bluffing
, and start folding even when you're getting 6:1.
3) Be good preflop. Read all the old hand chart discussions, and digest a ton of info. Postflop plays itself a little bit because the pot gets so big.
4) I played HORSE from $1/$2 to $15/$30 up until a couple of months ago, and I had pretty similar issues (weak at LHE, LO8). Message me on AIM @ "c9h13no3hcl" if you want any advice.
Oh, and moving up in stakes will NOT help you win more.
