Deep Stack NL Hold'em Theory

[jdefoe]

On GSN's High Stakes Poker, I noticed preflop that players often limp in with suited connectors and suited gappers like 5 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/heart.gif[/img]from any postion. Why are they doing this? Why would you do this in this game but not in a tournament?

and, in the WSOP, why does Daniel Negreanu play every hand? And, did he mainly play the hands calling in position or just raising every pot regardless of position?

thanks
