For what it's worth, here is my read from when I played 200 full with Renton:

o Plays good hands and plays them very fast, will back-up aggression, gives lots of post-flop action.
o Doesn't play blinds much. You can open light (and not just CO/BN), because he often folds.
o Outside of HuD stuff, poor reader of players

Constrast this with a guy like Lukie who gets out of line less, bluffs just enough to make you wonder, manages pot size, puts you on a hand and will make a laydown.

edit: One other thought. Learn how to induce routine bluffs. Another possible issue here is that you're starting to run into more people who know how to deal with players who pick good starting hands and just POUND POUND POUND.
