I have my own system of note taking that has proved very successful and I have certain things that I look for. Another reason is that I want to know what a player is possibly feeling now...this minute and not just blindly follow some notes of what they did two weeks ago. Has a player just had a series of vicious outdraws and has then started raising like a crazy man, are they tilting, possibly feeling tired etc. Just because you cannot physically see them does not alter the fact that there are human beings behind those avatars and screen names and they suffer from emotions just like everyone else.
If you try and become at one with the screen then it is surprising just what information can actually be gathered. Much of which would be beyond the capability of poker software. I do not multi-table for this reason also. Multi-tabling may work for certain players but a massive amount of information is lost when you do this and your earn rate per table falls dramatically. Another reason that I do not multi-table is that it starts to feel that I am not actually playing poker, just some glorified fruit machine.
By 10:30 am, I am ahead by 24 big bets which is $1440 but I have also had my share of luck. This is far and above what my hourly earn rate is but you have to take the rough with the smooth especially in a game like limit hold'em where the overlay of a good player is nowhere near as great as it is in no-limit hold'em. I get dealt A-K again, it feels like I have had this hand a hundred times today and another pot comes my way.
I do not let my emotions carry me away when my session goes through the $2000 profit mark at just after midday. The day before yesterday, I had lost over $1500 on another site. Limit hold'em can be a very frustrating game to play especially at the lower limits below $10-$20.
