I made a similar post here:

ok, i'll dual post... i've been meaning to do this for a while.

i use the following: #hands, bb/100, vpip, pfr%, call pfr, SDinfo, agg freq, WtSD, W$SD, WSDRT, WSDRR, Fold Flop Bet, Fold Turn Bet, Fold River Bet, Fold Flop Raise, Fold Turn Raise, Fold River Raise.

Explanations:

# of hands - helps determine accuracy of stats

bb/100 - shows me whether this guy is a moron or not. can vary widely when # of hands is low. i often use it to determine whether to respect someone's bet or raise (esp. in plo8 -- a nuts game).

vpip - basic info

pfr% - this is useful for seat selection. i often try to sit to the left of the aggro pfr people.

call pfr - this is useful when you want to see how much or how little action your raises will get. if this is high with a lot of players, you don't want to raise to thin the field -- it won't work.

agg freq - i was using agg factor before, but i find this as useful if not more so.

Went to SD - i like to know who's a monkey and who's not.

Win $ at SD - some people show down at a reasonable percentage, but they showdown a lot of junk. this is useful to know if you are playing a non-nut hand (in plo8) or a non-strong hand (e.g., TP weak kicker in 6max lhe).

Win SD when Raise Turn - does that raise mean anything, or is he just posturing and/or looking for a free SD.

Win SD when Raise River - does that raise mean NUTZ or does he value bet with marginal edges... or does he raise in an effort to get the best hand (but non-nut) to fold. MK, this stat's for YOU!!!

Fold to various bets or raises - This tells a lot about a player's strategy. for example, some players like to see the turn before they fold their junk. others fold on the flop -- fit or fold types. others just don't really fold much at all. the fold to raise bets are useful to determine whether you can push them off a hand or not with a raise. if they reraise you, you can often define their hand by looking at the WSDRT or WSDRR stats. if they don't fold, you should only value raise rather than count on fold equity (esp. for LHE).
