Let’s review Why did I switch positions and use 2.5x Martingale to bet on Spain? The score was one factor, but more importantly, France’s defensive core, Saliba, had to leave after 30 minutes due to a back injury. Their defense fell apart. And then there’s Digne, who gave away a penalty to Spain— he’s the weak link of the team, and the weak link effect became obvious. Meanwhile, Spain is balanced. The longer they play, the more brutal the weak link disadvantage becomes. So, during halftime, I directly reversed my bet.
