Yes.

oic because we usually play against the same players day in day out online. makes sense?

Its more along the lines of taking what information you've gathered from table, while you've been there. And making your decisions accordingly.

If I'm trying to make money I'd rather be at a table full of donkeys than a table full of good players. Even though occasionally the donkeys will make me question why I try. And this is coming from someone who has recently had their bankroll raped by variance/donkey-fuckers on PokerStars.

I have more than 1k hands on certain players, I associate with higher level players who talk about having 2-3k on regs at their stake. So...whatever man.
