I have been grinding a lot of nl400 and winning nicely. But I have trouble beating nl600 (and nl800 games) if there arent any super fish sitting at the tables. On the other hand there are more 1k games going on and I have been thinking that is nl1000 sort of an entry level and 600 and 800 games have more 400 graduates? Sort of the same like nl50 might be tighter than nl25 and nl100 because 25 and 100 are entry levels where as nl50 is full of tightish nl25 graduates..
Anybody else noticed the same?
