I like to isolate alot in LP, so a player that limps alot, but has a rather high fold to c-bet% is rather ideal. Or ones who love to limp/fold. And i find that alot at 50nl on stars. Players either limp/fold, or limp/call, check/fold. So that's fun ..

Also a player that is incredily passive on all streets (AF 1ish) makes things very easy. You can build a pot when you want because they tend to still call with shit, but you can also keep it small when you need to.

I have a question, well regarding the fish you stated (High vp$ip and low pfr). I realize we need to attack these players, and assume isolating their limps with any hand with potential is a good way to do this. But what about the rare times they raise? Should we tend to 3b them lighter, or just increase our calling range?? I'm rather sure it's the second, just never been told for sure. So still 3b our value hands but instead of 3b bluffing just add in alot of those hands into our calling range (suited aces, suited one gappers, etc)?
