So I guess to start... Limits in a game there are 2. a low and a high- when are each used... like does the player have a choice when they are betting or does each round have a specific limit (from the 2) and thats the amount you bet.
Just to answer this specifically:
You'll see the stakes for a game listed or described as, for example, $1/$2. That can mean two different things depending on whether the game is a
fixed-limit game (which would be called "one-two limit") or a
no-limit game (which would be called "one-two no-limit").
In a
no-limit game, the listed stakes are the
blinds. The first number is the
small blind and the second number is the
big blind, these being the forced first and second bets by the first and second players in the first round of betting. Subsequent bets can be any size, up to the bettor's entire stack of chips.
In a
fixed-limit game, the listed stakes are the
bet sizes. The first number is called the
small bet and is the bet size used in the first two betting rounds. The second number is called the
big bet and is the bet size used in the last two betting rounds. Every bet or raise in fixed-limit games is always the same size, either the small bet or the big bet depending on which betting round it is. The exception is that at the start of the first round, the first player must post the small blind, which is a forced bet of half of the small bet. The next player must post the big blind, which is a forced bet of the full amount of the small bet.
