Of course, a strategy with bets on high odds always has a bad chance of success. But if you choose more equal opponents who will have approximately equal chances with high odds, that's what I like. Only on condition that the player is well versed in this sport, these teams, leagues and players. Moreover, this is exactly how I bet, of course I can't boast that I am a winning player, but I like to play this way, try this strategy. But I am absolutely sure that I will never bet with the smallest odds. I have seen many times how people lost huge money there, thinking that they could win and take a hundred bucks, and in the end they lost thousands, so sad.
A very good strategy by your description, in as much as there's actually no exact pattern or sure strategy that is void of you loosing at some point. But then taking the bet on the players will be a very good option to explore as it will give you a better chance even to win your bets more often than you will if you make outright bets on the teams.
