You can only stay away from those games that you have little or no interest in. I mostly bet on soccer, tennis and basketball. I avoid cricket since I know nothing about the rules. Rugby is another sport that I rarely place wagers on, even though I know something about the rules.
I'm fond of betting on soccer and basketball. I wouldn't say that I stay away from any particular sport; I'm the kind to explore the unfamiliar territories. Does anyone here bet on cricket? This, to me, looks like the most complicated sport ever.
Yes, I stay away from a lot of sports because it doesn't catch my attention, so I don't bet on them. I applaud anyone who is any good at betting on cricket.
You will never find me betting on tennis since I believe that 2 hours or thereabouts is such a long time to keep checking if you have won. I prefer basketball because excluding the games that exceed the normal time, in around 50 minutes, you are done!
I stay away from Cricket, American football and rugby. I prefer to only bet on games that I have a big understanding of. On the contrary, there are people who love to try the unfamiliar territories and as a result, make huge fortunes.
