"Consider your appetite for disagreements" by Adam Zerner

Poker

There was a time about five years ago where I was trying to get good at poker. If you want to get good at poker, one thing you have to do is review hands. Preferably with other people.

For example, suppose you have ace king offsuit on the button. Someone in the highjack opens to 3 big blinds preflop. You call. Everyone else folds. The flop is dealt. It's a rainbow Q75. You don't have any flush draws. You missed. Your opponent bets. You fold. They take the pot and you move to the next hand.

Once you finish your session, it'd be good to come back and review this hand. Again, preferably with another person. To do this, you would review each decision point in the hand. Here, there were two decision points.

The first was when you faced a 3BB open from HJ preflop with AKo. In the hand, you decided to call. However, this of course wasn't your only option. You had two others: you could have folded, and you could have raised. Actually, you could have raised to various sizes. You could have raised small to 8BB, medium to 10BB, or big to 12BB. Or hell, you could have just shoved 200BB! But that's not really a realistic option, nor is folding. So in practice your decision was between calling and raising to various realistic sizes.
