What Are Pot Odds?
Pot odds are the ratio between the size of the pot and the amount you need to call. They tell you what percentage of the time your hand needs to win for a call to break even over the long run.
If the pot is $100 and your opponent bets $50, you must call $50 into a total pot of $200 (the $100 pot plus the $50 bet plus your $50 call). Your pot odds are 3:1, or 25% in percentage form. Your hand needs at least 25% equity against your opponent’s range to justify the call.
