I am not a limit expert, but I've looked through all of the DERB hands posted in this thread and, from that dozen or so, already see two common plays. At least one of them is something relatively difficult to exploit theoretically and unobservant opponents will never catch on. (Specifically, when he runs into resistance with any overpair, he's almost automatically raising when the board pairs. Coupled with his aggression on prior streets, he probably doesn't get reraised often.)

I have no idea how he plays outside of that, and some of those river calls are horrible. But I think he is at least attempting to study the game - either that, or being trained by someone who does.
