» What adjustments should a tournament player make when they move to cash games?

Each variation of poker has different dynamics that you must adjust to regularly.  Tournament players must adjust to a blind that doesn't ever rise and the ability to rebuy if they go bust.  These change the game considerably.

"He should be humble and watch good players," says David Oppenheim, who plays the biggest cash games in the world. "Try to learn from the players around you. To be a really good cash-game player, you need lots of experience." 

It also helps, notes Oppenheim, that cash game players hate to lose. "They are unattractively competitive... They just have an innate refusal to lose."
