i'm not exactly getting the advice i was hoping for here, maybe i'll give it some more time. i'm not saying that one should largely depend on notes taken on a player, but most of the time when I post a controversial hand I get asked what's the read, and I basically never know! It's not that I have no information, it's generally that I have no clue what to do with, which is why I'd like to take *better, more useful notes* and want some advice on that.

What exactly SHOULD i know about a player that will help me make the right call/raise/fold in a specific situation.

From my recent experience, the more aggressive i try to play the more i get screwed, and since I almost never play with the same people again (sng's for instance) I only have a very limited time I play with people, say a hundred hands tops.
