Note taking while playing online

[IndyFish]

I also note specific information. Some players will ALWAYS bet from LP on the flop if there was no action before them. Note what hands they raise with, or DON'T raise with (I've seen some that won't raise with AA).
I also always date my notes. You can put more stock into recent notes than something from a year or two ago.

Make sure to read every hand history when it shows down. There's an absolute wealth of information in every one. At the low stakes you can be pretty sure they aren't mixing their game up so if you see them slow play a set they *always* slow play a set. If you see them min-raise a draw in position, they *always* min-raise a draw in position.

I typically write down the hand history and how the villan played the hand. Some general notes like 'called w. 2nd pair on a K8xxx board for 100bbs' or something like that.
