I just adopted a new gambling strategy which is that I don't bet on which club wins the game, but I bet on how many goals would be scored in the first half or which team will score first. What I do is to check the recent performance of the strikers and how long have they being scoring in first half.
However, you gambling strategy can be different from mine but what matter is that if we're not lucky, no matter the research that we do, we will lose the bet.
anyone can have a different strategy as long as you think it works for you. the OP's list may work for him but it may not work for others. this is the good thing in betting, you can have your own disposition in your bets because that's your money. so mind your own business and look for your own strategies which you think can be of your advantage.
About the points, you're telling the potential drawbacks whenever a club is on the lead. Like in any sporting activities, the point can't determine your win while there's still time remaining and that's why don't be confident until the game ends. There is no strategy that you've said on this but they're all some situational thoughts that you're telling us based on how you perceived that particular sport that you're betting. The factors you've said, they're not strategies and even if I try hard to comprehend them.
for him, that's his approach on how he bets. so it may work for him but for others, it won't. so just take it as a tip but not totally applying it to your bets. we have our own strategies on every sports. for the OP, that's how it works on him.
there are also quite a number of factors to consider when you bet -
> familiarity with the sports / athletes
> actual performance of the athletes
> known injuries / health conditions of the athletes involved
> coach
> weather conditions
