All in poker 101: Key strategies and tips for success

Poker has grown massively in popularity in recent years, thanks to televised tournaments and online platforms being easier to access than ever.

The “all in” moment is often seen as the ultimate high‑stakes thrill in the game, and while many players dream of that defining moment, going all in requires skill, timing, and discipline at some of the best online casinos. With the right mindset, you can use this bold move to your advantage at the table.

However, over‑committing at the wrong time can cost you your stack really, really fast. Here, I’m going to explain what going “all in” means, how it works, and when, and when NOT, to use it! I’ll also cover side pots, bluff tactics and key strategies for making all‑in moves with confidence, so let’s get into it.

What does all in mean in poker? In pretty much all types of poker, “all in” means a player bets all of their remaining chips on a single hand. Once you go all in, you can’t make any further bets in that round. If other players continue betting, side pots are created.

Going all in is a high-risk move often used to pressure opponents/bluff or maximise value with a strong hand, so this isn’t something to try if you’re just learning how to play poker.

Poker all in rules A player may go all in at any point during a hand when it’s their turn to act. Only the chips already on the table can be used, players cannot add more mid-hand. If a player goes all in and others call with more chips, side pots are created. The all-in player is only eligible to win the portion of the pot they contributed to. All-in moves must be clear, either verbally declared or physically pushed in. In no-limit poker, all-in bets can be any size, up to the player’s full stack. How to go all in poker? To go all in, wait for your turn, then either announce “all in” or push your entire chip stack into the pot. Why? Because this signals that you are betting everything you have left. You can go all in at any stage: pre-flop, post-flop, turn or river, but once the move is made, you can’t take it back or make further bets in that hand. If multiple players call, side pots will be created to manage any excess bets. Going all in can be a powerful tool when used at the right time and with the right hand.

When going all in is a good idea Going all in makes sense when you’re short-stacked and need to stay in the game. For example, in some of the best online poker tournaments (with 10 big blinds or fewer), an all-in shove can pressure opponents and potentially double your chips. It’s also wise when you hold a premium hand, like pocket aces or a flopped full house, and want to extract maximum value. 

Additionally, all-in moves are effective when opponents show weakness and folding equity is high at the table. In these situations, the risk-to-reward ratio justifies aggressive play and can help you regain control.

When to avoid going all in Avoid going all in with marginal or speculative hands, especially when you’re deep-stacked. For instance, shoving pre-flop with King-Ten offsuit from an early position can backfire if you’re called by a stronger hand. 

It’s also risky to go all in against multiple opponents, as the chance of someone holding a better hand increases almost exponentially. Similarly, if you’re in early position and unsure of other players’ intentions, an all-in bet might expose you unnecessarily. In these cases, a smaller, more controlled bet gives you room to fold or adjust your strategy, based on how others act.

Going all-in as a bluff Bluffing with an all-in can be effective, but it’s a really high-risk tactic. This move works best if you’ve already built a reputation for strong hands at the table. For example, on a dry board where your opponent checks the turn, an all-in shove can represent strength and force a fold.  It’s also more likely to work if your opponents have medium-strength poker hands, such as top pair with a weak kicker. However, bluffing all in too often becomes predictable and dangerous, so your success with it relies heavily on timing, table dynamics and accurate reads of your opponents.

Purpose of side pots Side pots are used in poker when one or more players go all in and others still have chips to bet. They ensure fair play by separating extra bets that the all-in player cannot match. 

For example, if Player A goes all in with £50, Player B calls with £50, and Player C raises to £100, a main pot of £150 is created (from £50 each), and a side pot of £50 (from B and C) is formed. Player A can only win the main pot, while B and C compete for both. This keeps betting balanced and organised and is always implemented by the best online poker sites .

Mastering strategies for going all in poker Using the all-in move effectively requires timing, discipline, and awareness of the game situation. Here are some key strategies to follow:

Know your stack size – Short stacks (10–15 big blinds) often justify all-in shoves. Assess hand strength – Only shove with strong or well-timed speculative hands. Use position wisely – Late position gives more information before acting. Target weaker players – All-in moves work best against cautious or indecisive opponents. Avoid predictable patterns – Mix up your play to prevent being easily read. Read the table – Watch for betting habits and opponent tendencies before shoving. FAQ What are the risks of going all in? Going all in risks your entire chip stack in one move. If you’re called and lose, you’re either eliminated (in tournaments) or need to rebuy (in cash games). It removes flexibility and should only be used when the reward outweighs the risk.

Can I go all in pre-flop or only post-flop? Yes, you can go all in at any point: pre-flop, flop, turn or river. The timing all depends on your hand strength, position, and stack size. Pre-flop shoves are common with short stacks or premium hands, especially in tournament play.

What is a fake all-in? A fake all-in is when a player pushes chips forward to give the impression they’re going all in, but still holds some back. This is often used to manipulate opponents, though it’s frowned upon and may be considered unethical or against house rules.

Can a player be forced to go all-in? Yes. If a player doesn’t have enough chips to call a bet or post blinds, they are automatically all in for their remaining stack. They can still win the main pot but are not eligible for any side pots created.

Can I go all in with any hand? Technically? Yes, you can go all in with any two cards. However, it’s usually only advisable with strong or strategically chosen hands. Random all-ins without a plan often lead to quick losses and early exits from games.

How does all-in work in tournaments vs. cash games? In tournaments, going all in means risking elimination if you lose the hand. In cash games, you can rebuy after going bust. The risk is the same, but the consequences and dynamics are different, making all-in timing more critical in tournaments.
