Gambling is a thing of luck and your intuition may disappoint you when result of your bets emerge. I believe in doing proper research about the teams I bet on before casting my stake. It's important to know the forms of their players and their availability before you can make decision. It helps give you the insight to make better decisions while gambling.
Researches isn't very accurate since players can still mess up your predictions by indiscipline on the field of play and some of them are sent off, reducing your chances of converting your bets, which boils down to winning bets being about luck, but with knowledge rather than mere intuition, your chances are higher.
Betting is not just use intuition but it depend on the research and analysis and your luck. So even if you trust intuition, you still need to those things to give you the chance to win in gambling. If you don't use those things instead just use intuition, you may difficult to win because your intuition can change into greediness especially if you win before.
Research will not always give the win but at least, you know how to pick the right team that have a chance to win. You need to improve your skill in betting so you don't have to use your intuition but you use your skill to analyze the match.
