What is opens is a possibility of calculating winning odds by considering the number of players, the two cards in your hand and the open cards on the table.
The five cards are opened in 3 stages – In the first round of betting there are three cards and a certain amount of people playing. In the second round there are four open cards and the number of people still playing can be changed. In the last round there are five cards open and again, the number of players can be changed. In each step the odds calculation needs to be adjusted to the situation in hand.

There are varies calculating tools, some free and some not, some are available online and some requires downloading to your computer.
