Micro cash games
I play only micro limit PLO cash games now, some basic strategies:
Play all 4 cards working together
2 pair is crap, a set is only good if none of the board cards are working toghether and the board hasn't paired.
Ck or call with flushes below K high and the board hasn't paired
Never play the idiot end of the straight unless everyone is checking all around.
Be careful of pulling the FH with low set and middle pair, like 4's over 7's when board pairs 4's. Often something like Pocket 9"s making a set will dominate you.
Don't raise the pot pre-flop in position unless you have a very good starting hand, then raise at least 4x BB to limit calls.
If flop is dead or very marginal fold to raises otherwise check.
Don't slow play unless you are WAY ahead and want to keep as many in pot as possible, I'm talking K's over J's FH hands with pocket kings. Nut or 2nd nut flush on flop (happens more times than you'd think) raise pot don't slow play.
About the only time you can
bluff on showdown is the A bluff with flush, and then you have to bet big. Otherwise bluffs get called far to often with straights or Q high flush.
Like all poker everything is relative to your villians and being able to read them.
