When you stake all of your chips, you are said to be all-in. All betting rounds in the game, including the preflop, let players to go all-in. An all-in is used in No-Limit Holdem in the following circumstances:
The “premium” hand has been gathered by you. The best rounds to go all-in are Turn and River since later in the game, opponents are more likely to call your bets.
You’ve got a strong hand. It is a good idea to increase the stakes if you are certain that your hand will produce a powerful combination on the flop stage. Making an all-in might be a wise move if the opponent calls aggressively.
You want to bluff because you have poor cards in your hand. It’s a common scenario in movies for someone to go all-in with a bad hand, but you shouldn’t do it unnecessarily in real life.
You are a participant in the tournament and have the largest chip stack among your rivals. You make an all-in and increase your stack with blinds and ante since you know that players with lesser stacks will do whatever it takes to win the event. Players that have larger stacks play more aggressively than those who have lesser stacks.
However, your rivals also have the option of going all-in. The best course of action in this situation is to simply examine your cards; if you have a powerful hand, you may call with confidence, while folding is preferable for those who have a bad hand. Depending on the amount of large blinds given to each player and the potency of the combination, the stack is divided if several players go all-in.
