It would be great for any poker player to access any of the available poker websites and simply start playing at a randomly chosen poker table, but unfortunately this is not that simple. You will have to experience several online tables before you finally find one that you are comfortably playing at.
For instance one criterion of selection is to aim for that site displaying a smaller pot size instead of going for those with large pots. If you are a beginner you need to give it a try to the smaller pots (having an average pot size between 70 and 100) prior to venturing to the other alternative.
Also do not keep playing at a poker table where you lose with every single hand you play. None of the available sites will force you to stay more than you want, so quit a table when you see that you are constantly losing.
