Poker Betting

The first thing to note is that whatever betting limits you are using whilst playing poker, you can never lose more money than you have in front of you on the table, so all those films with people playing for a few dollars and someone suddenly loses their house/car/shirt etc, can't happen!

That said there are huge differences between the different betting structures used in poker, and these are outlined below.

No Limit

This is the most common betting structure for Texas hold'em, and is by far the most popular over all formats, cash, stt and mtt.

Basically it does exactly what it says on the tin - there's no betting limit, and you can bet anything from a minimum bet (the size of the big blind) up to all of your chips, during any betting round!

This means that at any point you can be put to the test for all of your chips at any point in a hand if your opponent has equal to your stack or more.

Some online poker sites offer capped no-limit cash games, where if a player wages a certain amount he is considered all-in, and can bet no extra over that amount, nor fold out of the hand. In this way the volatility of no limit is reduced.

Pot Limit

This is the format most commonly used for Omaha and Omaha hilo games, both cash and tournaments. It is often used for stud games as well, and occasionally for Texas hold'em.

Under this structure a player can bet anything up to the size of the pot at that point. If a player has a bet to call when it is his turn to act, he may raise by the size of the pot after his call.

For example, pre-flop in a PL tournament, with blinds at 50/100, the first player to act could raise up to 250 more, putting in 350 total, but decides to just call the big blind. The next player to act may call 100, or raise up to 50+100+100+100= 350 more, 450 in total.

If there is no bet for the player to call, then the maximum bet amount is simply the current total of the pot.

In some cash games, for simplicity, the small blind is considered to have "completed" and made up the big blind, and for pot size calculations is treated as a big blind.
