Questions people ask
- How do you calculate pot odds?
- Divide what you have to call by the total pot after you call. If the pot is $20 and your opponent bets $10, you call $10 into a $40 pot: 10 ÷ 40 = 25%. You need to win at least 25% of the time.
- What is equity?
- Your share of the pot based on how often you'd win from here. If you win 30% of the time, you have 30% equity. A call pays off when your equity is higher than the pot odds.
- Should I call with a flush draw?
- With one card to come, a flush draw hits about 19.6% of the time (9 outs out of 46 unseen cards). That's enough to call a bet of about a quarter of the pot or less (you need 16.7%). Against bigger bets it isn't, unless you expect to win more when you hit.
- What are implied odds?
- Chips you expect to win on later streets when you hit. They can make a call worth it when the pot odds alone aren't quite enough, but only if your opponent has chips left and will pay you off.
- What is the rule of 2 and 4?
- A quick estimate: on the flop, outs × 4 is roughly your chance to hit by the river; on the turn, outs × 2 is roughly your chance on the river. It runs a little high with more than 8 outs.
