I would agree that 5NL-10NL is basically the same strategy. I agree with above that at 25NL villains can be much more aggressive and you need stronger reads to go after bluffs. Lower levels (2-10NL) you won't find as much bluffing
, so it's easier to play straight ABC poker and make a profit. Of course, you will find that certain tables are much more challenging than others, and the more players you know at the table (playing style-wise), the more likely you are to capitalize on the action. The more I've played the more I've discovered that table selection is a huge component of making a profit. Gl!
