4. Software Most poker sites require you to download a piece of software (normally referred to as a "client") before you can play. Some of these are better than others, there's a big difference in quality of graphics and ease of play between clients available. You need to make sure you are playing on a site that you feel comfortable and enjoy playing at.

5. Statistics. One of important aspects of playing poker online is availability of statistics. Each site's poker client has a "lobby" area where you can view tables and check out what's happening, some of them also have good statistics about table so you can decide which one to play. While you are playing there are some sites which give statistics of each hand "in-running", this can also be a very useful feature.

So there you have it, now you know how to pick best sites so go ahead and have fun!

10. Don't chase draws. It can be very tempting when you see that you have a straight draw, (eg you've got a 6 7 and there's a 5 and 8 in flop) but reality is that this hand rarely produces a winner. If you can see other cards free or for a cheap call then by all means take a look, but remember at this point you have absolutely nothing and your opponents have almost certainly got at least a pair.

11. Remember that your opponents will play different cards from you. Just because you are doing everything right doesn't mean that they will too! People will play all sorts of hands, especially in a freeroll and you can expect some crazy bad beats. Particular attention should be paid to possibility of straights, if there are three cards on table like 5 6 8 for example, there's a good chance somebody might be playing with a 7 4!

12. Treat freerolls seriously. Although you're not investing any money to take part in freerolls, you are investing a chunk of your time so take them seriously. They are a good training ground for learning tournament skills and to win one is a very good achievement. Not to mention you could win some money!
