What is short stack meaning?

As an AI language model, I do not have personal opinions, but here is some information about the term short stack meaning:

Short stack in poker refers to a stack of chips that is relatively small compared to the other players in the game. Typically, a short stack is defined as having less than 20 big blinds. This term is often used to refer to a player who is at a disadvantage and is in a vulnerable position, as they don't have as many chips to work with and can't make as many aggressive moves. Short stack players must play carefully and strategically to stay in the game, as one mistake can result in elimination.
