Pre-Flop All-In

All-in before the flop

In this article, we’re going to discuss what is sometimes known as the nuclear bomb of no-limit hold’em: moving all-in before the flop! No matter how much we try to avoid it, there just comes a time in almost every tournament when we find ourselves sitting on a short or (at least shortish) stack. While this is not a desirable spot to be in, it does in some ways simplify our decision-making process; because we’re down to a kind of all-or-nothing situation. Either we’re going to fold our hand pre-flop or we’re going to push all-in, in the hopes of doubling up! There is really no in-between…

Why Move All-In Pre-Flop?

Why would we ever consider moving all-in-pre-flop and risking all of our chips? Well, there are really two good reasons for this.

  1. By moving all-in we place all of the pressure in the hand onto our opponents, who need to decide if they are willing to risk a significant portion of their stacks to call our bet. Because it’s such a significant portion of their stacks, we’re putting a lot of pressure on them; so they are very likely to fold! That’s really good for us, because just the Blinds and Ante sitting down on the table will represent an increase to our stack of usually about 25 to 30%. Something we really want when we are short stacked.
  2. Moving all-in saves us from having to make a tough decision after the flop. Especially, when we are in a hand against post-flop player.

What If We Raise?

For example, let’s say the blinds are $200 and $400, and we have just 10 big blinds. We have 4000 in our stack. And we’re in middle position, and we find ourselves with an Ace and a King. If we make a standard 3x raise and get called by a player on the button who has 30 big blinds in his stack, what happens whenever we see a flop of Seven of Diamonds, Four of Clubs, Nine of Diamonds? All we have is two overcards on the board. What does our opponent have? Did he hit? Does he have a pair? A flush draw?

With over eight big blinds in the pot and just seven big blinds left in our stack, what are we supposed to do? Do we bet our hand? What do we do if he calls? Are we supposed to check and see if our opponent is betting purely to put some pressure on us? If he does move in, are we supposed to call with just Ace-high? Are we supposed to fold? What do we do? This is a really tough dilemma. And it’s one that we could actually have avoided if we had just played our hand differently.

What If We Move All-In?

Let’s look at the same situation, but this time instead of raising three acts preflop we just move all-in.

  • Moving all-in-pre-flopThe first thing we notice is that instead of risking just 10% of his stack to call our hand we’re now asking our opponent to risk fully one-third of his stack to stay in the hand. And that’s a huge difference. We can really do a lot of damage to his stack.
  • The second thing that we notice is that we no longer really have to worry about making a difficult flop pot decision because all of our money is already in the middle. So the hands just going to play to showdown and we’re going to get to see five cards.

So, how do you decide on whether or not to move all-in before the flop?

Well. As we’ve already pointed out, the most important factor in making this decision is really making the size of your chip-stack in relation to the size of the blinds. If you have a stack that’s only about 10 big blinds, you’re looking to move-in really in the early and middle positions with any pair and nearly any decent face card that has something with it, like, you know, King-Jack, King-Ten, Queen-Jack, Queen-Ten, those kinds of hands. Now, if you are in the late positions, like on the button, and everybody happens to fold around you on the button, and you’ve got (say) 10 to 12 big blinds, you could actually consider moving-in without looking at your cards, because the probability that the small blind and the big blind are gonna fold is so high that you’re almost always just going to get those blinds and antes into your stack. And you know what? If you do get called, you can still win; because, you know, any two cards can actually win!

Likewise, if everybody moves around to your small blind, and they’ve all folded, you could also move in the small blind without really looking at your cards when you’re in that serious serious danger zone of like 10 big blinds. Now, when you get into the 15 to 20 big blind range, you can be a little choosier about your hand selection because you still have time to wait, but you don’t want to be too much choosier. We mean, we wouldn’t recommend ever moving-in without looking at your cards when you have as much as 15 to 20 big blinds; you’re not that desperate yet!

Ideally, you always want to be the first player to act, when you finally do decide to move all-in. This is because it’s always better to bet all-in, than it is to call all-in for your tournament life, because your opponents can fold when you’re betting, and you can pick up all those blinds and antes. When you’re calling, you just have to win the hand.

Now, of course, when you have a really good hand, that you actually believe to be better than the hand your opponent has moved all-in with, like, you know, you have Aces or Kings or Ace-King or Queens or even a hand like Jacks, then calling all-in is certainly acceptable.

Timing is Important

Another key to moving all-in preflop is timing. If you have a premium hand, you’re going to move all-in no matter what. But if you’re holding something more speculative, like King-Jack, you would ideally like to make this play against opponents who are likely to fold to your race.

If your stack isn’t very short, which is about 20 to 25 big blind range, then you can really use the all-in play as an effective way of re-shoving or re-raising an opponent when you can put a lot of pressure on him.

Let’s say again that the blinds are still that 200 and 400; and let’s say you have 20 big blinds in your stack. An opponent with 35 big blinds now makes a standard 3x raise from middle position, and you’re looking down to find a hand like Ace of Clubs, Jack of Clubs on the button. A hand that normally you might consider just calling with! Well, that is a good hand; but certainly, there are plenty of hands that beat it. Which means that calling that much of your stack when you’re already a little bit short might actually be a bad option. Instead, this is a spot where you really consider re-raising, and pushing all-in against your opponent, in order to push out any players with weaker hands than yours, and to apply the maximum amount of pressure to the original raiser. Without a premium hand of his own, your re-raise doesn’t give him the right odds to call, because he has to call 17X more, which is actually most of his stack. That means that not only can you steal the valuable blinds and the valuable antes in the pot, but you also get to steal his original raise! That gives you a lot of time to wait for a good thing to happen to you, so that you can really increase your stack later.
