yeah less tables is prolly a good idea.

i'm confused about the math...he went up 100, down 150, and is now down 250 total?

He is down TO 250. That's what I think anyways. What site does he play? Does he understand table selection? I sujest playing less tables at a time but sticking to 1/2

he's down 250 big bets ( 500 dollars ). he currently plays on betonbet ( pokerroom skin with rakeback ). he was playing on party for a while but quit in favor of rakeback on betonbet. he's also not playing with a PA hud or anything which i think is a mistake. in my opinion playing without a hud is always a mistake since one is so valuable at any limit.

also i was somewhat of the opinion that table selection was not terribly important at limits as low as .50/1 and 1/2. i'm sure that it is far less important than it is at 10/20 but i'd be interested to know if you all feel that it is very important at smaller stakes too.
