Also called All-in, it is the action of engaging all of your chips when you want to bet, call or raise.
It is a perilous action since it puts you in a situation where you can be eliminated.
If someone has more chips from you and has a better hand, you are eliminated. It is a very interesting weapon since it often shows a lot of strength and can scare your opponents.
When a player is all-in, they can only win a portion of the pot up to their contribution. If other players continue to bet, a side pot may be created for the remaining bets.
