As I always like to understand people, are you saying that you think the best strategy to win the match day betting competition is to go always for the result which you judge has the “best value” odds? In other words, if you think 1-1 should be 15 / 2 not the actual 13 / 2 you would choose it over the (say) 2-1 you actually think will be the result because the quoted odds for 2-1 look less “generous “?
I can see that might be a viable strategy if your predictions are no better than random. But if that was the case, why would your judgment of value be any better?
