If there was no variance in poker then Phil Hellmuth would win every time and poker wouldn't be a game anyone would play.
You know how Aces beats Kings only 82 % of the time? That 18% of the time Kings beat Aces, which is 18% of the time, is variance. If there was no such thing as variance, Aces would beat Kings 100% of the time. It's the universe balancing itself out because for every 100 times you are dealt aces and up against kings, you are mathematically guaranteed to lose 18 of those times.
Variance is the reason for a bankroll and the reason to play within that bankroll. You keep many buyins built up so you can over time beat variance. You try to make the right decisions every hand and over time the right decisions defeat variance. Poker pros is this not the main idea of playing poker. Not getting lucky but make profitable decisions over and over.
So, today in a live $400 local tournament, I make the right call of an allin bet on the turn, and the river gives the bettor one of his 2 outs to knock me out of the tournament. So even though I made the right call at the time, I still drive home early with empty pockets.
So variance is at play. I made the best play i could, the other player was not any better than me. What strategies can we employ to help beat variance, or do we just accept it?
