What is the 4 2 rule in poker odds? ›

The 4-2 Rule is a way of turning how many outs you have into your odds of hitting them. It's 4 times on the flop to hit on the turn or river, and simply multiply 2 on the turn to hit your draw on the river. E.g., a flopped flush draw is nine outs. Multiply this by 4, and the odds of hitting it by the river are 36%.

For a quicker way to determine your odds, multiply your outs by 4 on the flop, or 2 on the turn, to get a winning percentage. But poker is a game of incomplete information. To properly calculate pot odds, you must know exactly what poker hand you're up against.

In poker, the rarest hand is the royal flush. This hand consists of five cards in sequential order from 10 to Ace, all belonging to the same suit. The rarity of this hand stems from the specific combination of cards needed, which occurs only once in every 649,739 hands on average.

For positive odds, the formula is: 100 / (Money line odds + 100). For negative odds, the formula is: Money line odds / (Money line odds + 100). If the moneyline odds are -200, the probability of the event occurring would be: 200 / (200 + 100) = 0.67 (or 67%).

It is an estimate of equity. The player's number of outs are multiplied with double the amount of remaining streets. Using the example from before, the player had 4 outs with two streets to come. 4 outs multiplied by 4 (double the amount of remaining streets) gives an estimated equity of 16%.

The 7-2 Game is a side game in cash games where everyone agrees to pay a player if they successfully bluff with, then show, 7-2 offsuit. If you actually make a hand with 7-2 offsuit and win at showdown or have a bluff called you don't win, but if you can show a bluff you can collect a nice side pot.

To work out the percentage chance of an opponent acting after you holding a higher pair than you, simply multiply the number of players left to act by the number of higher pocket pairs, then divide by 2.
