how does the "limit" work. Like I understand it is a limit on the betting per time around the table but is there some sort of cap on the chips on the buy in?
In a fixed-limit game, every bet and every raise is always the same amount. So, for example, while in standard no-limit hold'em game if you decide to open-raise you might bet somewhere between 2x and 6x the big blind depending on your chosen strategy, in a fixed-limit game there's no need to decide how much to raise by. That decision is already determined by the stakes. Your only decision is whether to call, raise, or fold.
Fixed-limit games have a "small bet" which is the bet size preflop and on the flop, and a "big bet" which is the bet size on the turn and river. The big bet is twice the size of the small bet. The stakes are written using the size of the small and big
bets; for example, $1/$2 means that the small
bet is $1 and the big
bet is $2. In no-limit the stakes are written using the small and big
blinds; $1/$2 means the small
blind is $1 and the big
blind is $2. In a fixed limit game, the small blind is half a bet (i.e. half of the small bet) and the big blind is a full bet (i.e. an entire small bet), so in a $1/$2 fixed limit game the small blind is $0.50 and the big blind is $1.
Fixed-limit games usually have a cap on the number of bets and raises there can be in a single round, usually four. So for example, in a $1/$2 fixed limit game, the big blind bets $1, someone raises to $2, someone raises to $3, and someone raises to $4 and then no more raises can be made pre-flop. On the flop there's a new round of betting, which again goes up by $1 with each raise, until it gets capped at $4. On the turn the betting starts at $2 and can be raised by $2 each raise until there's been four bets/raises making it $8. Same again on the river.
Cash games don't usually have a cap on buy-ins, although sometimes home games do. Buy-in caps in no-limit games sort-of keep big stacks from bullying small stacks, although in cash games that's not really important (although a lot of people feel like it is). However, in fixed-limit games, since you can't shove your whole stack, there's not really any purpose to having a capped buy-in. The most you can bet in a single hand is usually 24x the big blind, so having 100bb or 800bb in your stack makes no difference to how a hand will play out.
Also I am new here, Should I not be asking all these questions in one thread? Or wuld posting too many threads be anoying? I just don't want to be a pain.
You should be asking your questions wherever and however it seems right. Don't sweat it. Questions are always great, and are a whole lot less annoying than the memes and insider jokes posted by the usual gang of
idiots regulars.
