as i choose whether or not to start a session
HALT: Hungry, Angry, Lonely, Tired. If I am any, don't play (friend told me that, if the credit goes to someone, please tell me).
Other odds (Stack to pot, starting hand goodness, etc)
Stack (how big is my stack relative to everyone else, which dictates how agro or not agro i play)
and other noteworthy observations.
sorta KISS, but its a ritualized and mnemonic way of playing sharp every hand, every session.
