The Double-Bet 

This is a quick lesson, but one of significance. The first thing to distinguish is between the double-bet and two individual bets. In the following scenario:

Player #1: Opens

You: See and call

Player #3: Sees and calls

Player #4: Sees and raises

Player #1: Sees and calls

You: See and call


Now, it shouldn't be very difficult to see the difference between the previous scenario and the next one:

Player #1: Checks

You: Check

Player #3: Opens

Player #4: Sees and raises

Player #1: Folds

You: See and call


Assuming the betting rounds consist of single unit bets, then you've invested the same amount of money in both scenarios, but you did it in two bets in the first scenario and in a single bet in the second scenario. That's the only difference between two individual bets and the double-bet.


You are subjected to a double-bet when not one, but two players have bet since the last time you did. This sends you a bet double in size, and if game theory holds up, you will fold more often to this double-bet than you will to two individual bets.


Whether psychological or mathematical, this important distinction is worth retaining. I'll repeat it: a player is more likely to fold to a double-bet that he is to two individual bets. This is important from both sides of the fence: 1) when you have a strong hand and are trying to keep more players in the pot, and 2) when you have a mediocre hand and want to improve your chances by folding more players. Let's take a look at some of the ways that the double-bet can be used to your advantage.



The role of the double-bet is important enough that it may effect your decision to call or raise, depending on the position of the initial bettor relative to your position. The moves above are all ways in which you can use the double-bet to your advantage or in which you may need to avoid using it. As it pertains to your game, you may also find yourself more willing to fold the double-bet than the two individual bets. It's tough to counter this when staying in the pot puts you at the mercy of other players' betting. The double-bet is effective because it is two bets at once with certainty. With the individual bets, you don't know with certainty that you're going to get a second one until there's an actual raise.


When you are subjected to the double-bet, it may be too much to invest based on the cards you're holding. In effect, you may be folded from another player's decision to eliminate your potential-hand from the pot. Further, if you find yourself seeing two individual bets in one round (and one of them from a check-raise), then you may have just been set up by a strong hand keeping you in the pot to throw away money. Defenses against this are few. The best you can do is never fold a hand that beats the bettor's hand, and never call one bet, two bets, or a double-bet if you can't win the pot.
