I think that in some moment every gambler thinks he has developed a strategy that helps him to get winnings or at least to minimize losses. That is usualy in good moments when bettings go well.
But actually at the end it turns put that it has nothing to do with strategy but just good luck and a bit of experience but rainy days need to come
Once you've get obsessed with big winnings and focused only on so called strategies gambling losses its charm and might become dangerous for you.
You do realize that the OP is talking about sports betting. Right? Sports betting isn’t just about luck. I am not just lucky to know that Real Madrid will squash a smaller team. People who do sports betting know when a win will be likely easy and when it’ll be a struggle. Like the match between Barcelona and PSG yesterday, that was the likely outcome because both teams are strong and it was going to be a struggle.
