Would love to echo the thoughts of previous responses which state that the ideal game to wager on is the one in which you have the most personal understanding.
However, I would also like to give a caveat. Tennis. I would never bet on tennis again. Many years back, when I was younger and much more stupid than I am now, I used to wager on (men’s) tennis. After a while, it occurred to me that my success rate was not anywhere near where it ought to be. I was only mildly unrealistic concerning what my success rate needs to be but my success rate was, objectively, very dreadful. I researched my stakes as best I could (in the time, Official Site of Men’s Professional Tennis | ATP World Tour | Tennis proved to be a treasure trove of statistics which could help you choose your own bets) but even allowing for”the house always wins” nature of gambling, I was dreadful. So, I decided to do some research of my own. As all tennis lovers know as Jerry Seinfeld expressed well, the scoring system in tennis is very weird. Four points to win a game, six games to win a pair (having an advantage of two) etc.. Fortunately, the ATP tour website provided statistics on total points won for every single game. I did a little study of my own. Across many of tournaments (it was a long time ago, I can not remember the number) I found that, on the ATP tour, something like 70-80% of games were decided by 5-7 points or not. Woah. Too close. Additionally, there’s no question of corruption. A number of pros (both good to quite good and journeymen) have been investigated for match fixing. This is a problem for each game where widespread betting is permitted but obviously more widespread in sports than larger team sports.
