“You don’t have to know your opponents, but if you don’t know yourself, you’re dead meat.” ~ John Vorhaus, Poker Writer and Player
“Ain’t only 3 things to gambling: knowing the 60-40 end of a proposition, money management, and knowing yourself.” ~ Pug Pearson, World Poker Champion
“Know Thyself” ~ the Ancient Greek aphorism inscribed in golden letters at the lintel of the entrance to the Temple of Apollo at Delphi, and inscribed in Latin (“Temet Nosce”) above the entrance to the Oracle’s kitchen in The Matrix
What is your poker play like when you’re hungry? How about when you’re tired? How about when you’re hungry and tired? What kinds of mistakes do you make at such times? How about when you’ve been up all night? Or when you’re angry? Or when you’re flush with money? Or when your day has been going badly? Or when you’ve had a couple of beers?
Know the in’s and out’s of your own poker play.
In other words, know yourself.
