In cash games yes. And I also try to seat select. Ideally I want to have fish and LAGs on my right and nits on my left, because it allow me to play most pots in position. On smaller sites, which is basically everything other than
pokerstars, you do however sometimes need to take, what is available, if you even want to play. At least when you get above 2-5NL. But in that case I will sometimes just not play cash games, if I can not get on a good table.
In the micros the rake is typically around 10BB/100 for 6-max and a bit less for full ring. And the reality is, you are just not going to beat that, if you only play against solid regulars. Every sensible player know that, which is also why, regular cash tables tend to break down, if the fish leave. Especially at 6-max, where there is rarely more than one fish per table.
