I have a friend who bets women’s tennis. He only bets huge favorites, like minus 600. He will bet 2000 to win 500 and I shit u not He is doing so well he quit his job. He only makes a few bets a week and rarely loses. He watches videos of the players and he can tell u everything about every player. It’s actually quite impressive, I’ve seen his bets prior to him placing them and can attest to his success. I just don’t have the 2000 to win 500. He normally can pick underdogs as well but says he wants guaranteed wins. He also is not a degenerate like I can be and has extreme discipline. A completely different but effective way of betting.
