If seat 9 is average I am going to take his money because I am above average.
Seat 1 is terrible. I am going to take all of his money.
I want to know if these two players are in the pot (pf) so I can act accordingly and maybe get in some marginal situations. I also want to decimate them post flop. Generally I always try to get the worst players (loosest, most passive ones) on my immediate right and don't put much stock in anything else.
The tag on my left is a little troubling, but if he doesn't know I'm a TAG I have a while before he 3-bets me with KTs.
Generally I try to put the good players on my left and the bad players on my right.
