I would practice for a few months on a website like pokerstars.net before trying to venture into the casinos. This will give you a good idea on whether you have it or not. There is a fair amount of skill involved, mainly on quickly figuring out the odds.
Chess blitz is pretty fun to watch actually. Most blitz tournament games are 5 minutes for each player. You also have bullet chess, where each player only gets 1 minute. The best player in the world probably (no such official title) for blitz is American Hikaru Nakamura. He's pretty obnoxious, especially for a guy who's only 21 years old. This is a cool video, even involves a bit of trash talking along the way (watch the trash talk carefully, goes by really quick). The opponent in this match, Varuzhan Akobian, is one of my kid's coaches.
