It probably should be mentioned that playing with almost 50BI's at 2NL and only 20BI's when we move up to $5NL has a very psychological effect when playing for stacks. You need to make sure you are playing your same game, because it is the same game. The only real difference is what you see when you look in the cashier after a session in terms of BI's.

Also, never consider yourself a particular stakes player. You only play according to BR, just because you moved up, be very aware of your BI's and move down if necessary. Your not a $5NL player or a $10NL player, your goals are much higher. Move down as easily and as untilted as you move up. Nobody successfully moves up to every stake they try. Some go easy, some go horribly wrong.
