I think I spend MORE time reviewing the game of poker as a whole than actually playing.
Whenever I am too tired or don't feel like playing, I usually spend that time reading poker articles
& guides, railing/watching all the different level of cash game tables to see how the "sharks" are playing at each level. I'm watching the MTT chip leader & shortest stack to see what they're shoving with.
I can go on and on... lol. Cliff Notes: I probably spend more time observing and trying to learn than actually playing. I hate playing while fatigued; it just leads to dumb mistakes.
