Don't Abuse the Fish
Everyone has heard this advice so many times that it's gets boring: "Don't tap the glass. You want to keep poor players at your table. Don't scare them off."
Personally, I'm not too concerned whether a particular fish stays or not. That may sound naive, but when you're playing 12 tables there are 96 other seats with players coming and going all the time so it's not worth bothering too much over any one individual. Besides if he did leave my table there's a good chance he'll sit down at another table where I'm playing anyway.
When you play so many full-handed cash hands each day, there is VERY little variance from month-to-month. Therefore, in the course of a month, you will win close to 80% of your 80/20s, and close to 90% of your 90/10s, and close to 96% of your 96/4s. The point is, it's not worth getting emotional about any pot that you lose as a favourite.
Although it's difficult, I try and remain calm and remove any emotions from my game. This means if I am to avoid getting frustrated when I lose a $500 pot with AA v KK all-in pre-flop, I also have to avoid any elation when I win such a pot. This frame of mind, in theory, should enable me to play my optimal game.
However, too often I find myself abusing the fish, with typical lines such as "You fucking useless cunt" or "You lucky fucking prick" when I should be remaining level-headed. The detrimental effect that this has is not reserved solely for the lack of emotional control. It often leads me onto pointless arguments which further distracts from my game- especially when I time out on my other tables.
Currently, I have simultaneous chat bans on Full Tilt and Pokerstars! I'd like to thanks Highstacks for his help with the Pokerstars one! :) This ban appears to have helped my game though. I am no longer able to abuse the fish and get side-tracked attempting to explain to vegetables why their play was terrible. I also don't have to feel bad later on for having called someone a useless fucker. I won't be requesting to have my chat privileges re-instated at the end of the 30-day period.
So my advice to multi-tablers is to either turn your chat off, or call everyone a cunt until you get chat-banned. :)
On a more important note, I've just taken a couple of photos of a great pair of tits which I'll post tomorrow.
