Mostly, I just use PT, and PAHUD, but if a player makes a certain play that doesn't fit with there profile, I will make a note to be aware of the possibility of an unusual play for them.

For instance, if a player is usually passive, and I see what pattern he uses to semibluff, I will note that. Or if a usually aggressive player, plays a certain situation passively, then I want to think about that.
