I have always spoken against strategy because it is not a pre-requisite or an important tool when it comes to winning in gambling, especially if what we are talking about is luck based games like slot and casino games..
But I love the context you are taking this from and to, coming up wit strategies to playing such games can be fun indeed, it adds some kind of life to the game, and this is actually good as long as the gambler does not start counting on his or her strategy to help him make better winnings.
I am not doubting the efficacy of strategies in sport betting games, even though I still would say that one strategy in this area also won't change the players styles and tactics on the playing field, but all the same, if it's still all what gamblers do to make their gambling experience more exciting and fun, then it's absolutely good.
I think that more experienced players should have a strategy, how they choose bets and how they follow a set of rules and do not exceed the risks. For people who play only for fun, it is clear that they will not care about strategies, because it takes a lot of time and implies the possibility of making gambling a way of earning money, which is actually very difficult. Maybe there are successful players who do not have a strategy, it is difficult for me to judge because I have not seen any statistics on this matter.
Experienced gamblers must have reviewed various issues before gambling and made their betting decisions. They pay special attention to risk-related issues. They are able to control themselves at that time without being emotional. But ordinary gamblers do not give much priority to these issues.
In gambling where everyone try to uses a strategy, but not all strategies work. Everyone, both experienced and inexperienced, tries to use strategies from their own perspective before placing a bet, especially those who bet on sports. But in the case of casino gambling, there is no strategy, where one has to rely on luck. Gamblers who prioritize strategy must constantly change their strategies. No specific strategy in gambling will ever bring good results in the long run.
