Betting rules for Pot Limit Poker  

When seated at a pot-limit poker game, the amount you are able to bet when it's your turn, is limited by the size of the pot. Your minimum bet is the same amount as the big blind and you can raise anything up to the amount in the pot. Here’s the thing, you can include the amount you need to add to the pot if you were to call the previous bet. 
I know its seems a little complicated, and sometimes learning poker can seem like you need a PHD in advanced maths, but the truth is that in a live poker room it's even worse. Have no fear though, because online poker makes it simple and even when playing live in a poker room or casino the dealer will usually be able to tell you the maximum bet if you ask. Many poker players make the mistake of thinking that pot-limit poker is less of a risk to your bankroll than if you play no-limit poker. Even though players are limited to the size of the pot, the reality is, most bets in no-limit poker are the size of the pot or smaller anyway.

 
Rules of Pot-Limit Poker 

1.  
   In a game of Pot Limit poker, the minimum bet is always equal to the size of the big blind. In a $1/2 pot limit game, Holdem or Omaha, the minimum bet would be $2. 
2.  
   If a player wants to raise, he/she must raise at least the amount of the previous bet on the table. So if you bet $5, and the player after you wants to raise, the raise must be at least $5. 
3.  
   The maximum bet is determined by the total amount in the pot including what you would need to call any bet currently in play. For example, in a game of Pot Limit Omaha, You bet $5 into that has $30 in it, and the next player wants to raise, the player can raise a minimum of $5 and a maximum of $35.  

Betting rules for No Limit Poker 

 
When playing no-limit poker, players are free to bet any amount they chose as long as it’s equal or greater than the big blind. Meaning players can move all their chips into the pot whenever its their turn to bet. 
There are rules to All-in bets. You're not allowed to move all in and throw your wallet or your car keys into the pot, this only happen in the movies. You cannot even change more chips or pull chips from your pocket or even take chips from a friend or another player. Poker rooms and casinos always use the “table stakes” rule. This means you can never bet anything more than the money/chips you are displaying on the table when the hand started. 

This begs the question, is it really No-Limit Poker? 

 
Many poker players make the mistake of thinking that no-limit poker is more hazardous to your bankroll than fixed-limit poker. It all depends on what stakes you play and how you play.  

No-Limit Betting Rules 

1.    
   At No Limit tables, players are free to bet any amount that they wish as long as it is at least the size of the big blind. On a table of $1/2 No Limit Holdem, players may bet a minimum of $2, and any amount up to the full amount they hold on the table at the start of the hand. 
2.   
   When a player wants to raise a bet, the raise must be a minimum of twice the original bet. If Bob bets $4 in a game of $1/2 No Limit Holdem, and Richard wishes to raise, Richard must raise a minimum of $4, so his minimum raise would be $8. 
3.   
   The maximum a player can bet in a No-Limit poker game is determined by the amount of money he/she has in his/her stack. For example, if you have $200 on the table, you can bet a maximum of $200 dollars only. You cannot add chips in the middle of a hand. 

Betting Rules for Limit Poker

 
When playing limit poker, or fixed limit poker as it is often called, the size of the bets are fixed. In Texas Holdem and Omaha games, the bets and maximum raise is the same as the big blind for the first two rounds of betting, so if you are seated at a $1 - $2 limit table, the first two round of betting can only be $1 at a time with a maximum raise of $1 at a time. 
There are a maximum number of 3 raises in these rounds after the initial bet. Therefore, on our $1 - $2 table, the maximum amount that each player can bet in the first two rounds will be $4. 
In the following two betting rounds, bets and raises are twice the big blind so now its $2 every bet and every raise.  
When you sit at a fixed limit table, the rule is to present the size of the small bet and the big bet. If you are seated at a $1/$2 limit table, you know that the first two rounds have $1 bets and the last two $2 bets. 
Many players make the mistake of thinking that fixed-limit poker is easier than no-limit poker. Another miss conception is that the pots are smaller in limit games. This is not necessarily true as players will often call a raise and stay in a pot rather than fold their hand to a large raise. More often there is more in the pot because there are more players in the hand.  

Fixed-limit games are another game altogether, and you have to play it differently and use different strategies to No-Limit poker games. 

 
Limit Poker Betting Structure:  

1. 
    Any limit game will have two betting limits specified, one low, and one high. For example, a game of $2/4 Limit Holdem will have blinds of $1 and $2, a low betting limit of $2, and a high betting limit of $4.  
2. 
   The standard bet in the first two betting rounds of a limit poker game is equal to the game’s lowest limit. For example, in a game of $2/4 Omaha, the bet size will be $2 on the flop and pre-flop betting.  
3. 
   The standard bet in the final three rounds of a limit poker game is equal to the game’s highest limit. For example, in a game of $2/4 Holdem, the bet size will be $4 the turn and the river.  
4. 
    Usually, there can be no more than one bet and three raises per round of betting. Once the third raise has been reached, betting is ‘capped’.  

Some games will remove the cap on betting when there are only two players left in the game.
