I have found cash games to be difficult, especially 100NL. I imagine certain level SnGs will have become much harder. I know that turbos at say the $27 level are a lot harder now than they were a year ago. I haven't played a $55 SnG for a few months, but I bet those are difficult now.

salsa's right though, you should probably be able to beat $5.50 SnGs. I do think that the micro stakes SnG players on Stars have become a lot better than they were back when I first started on them, though.

If you like MTTs, maybe that's one place where you won't notice an immediate increase in level of difficulty. Once you get deep a few people will know what they're doing, but MTTs attract a lot of fish and some of these fish get deep and make money.

I totally just rambled. Just my opinions and thoughts.

Edit: this is all on Stars.
