I get what he means.
So far its been interesting. I still find the fish that I did at 50nl, probably the difference is theres often 1 or 2 people at the table trying to target ME. At least thats how it seems. I'm probably playing a bit nit-taggish, but on the other hand I still seem to make some hero calls. I'm actually finding people who will semi-bluff more now which has been interesting. I think as long as I dont get into bluff wars I'll run ok.
