No I am not the best but I do try and be savvy. I see it all the time a good player or a player with an over inflated view of his/her abilities take a bad beat because someone sucks out on the river on a 2 outer and then they spew all of their poker advice like... "Don't you know who I am!" How dare you call my raise with trash and get lucky!
Also I'm playing the button and raise with an AK and get nothing on the flop, early positions are betting into me. Do I stay because "I'm the best player at the table", or do I fold am I still the "best player at the table"?
There are a lot of "Best Players" in the world who get knocked out of tournaments and games by rookies and average players all the time. There's a certain amount of hubris a good player should have, not too much, not to little. Like the game itself depending on conditions it's highly situational. 🙂
