Well this is a good question and there is not one over riding best way. You will find with experience which bookmakers offer the best odds on which sports, and then you can refine it still further to what bookmakers offer the best odds on either the favourites or underdogs for that sport, so that will be the first place to look. We provide lists of the best bookmakers on average on this site, but the best bookmaker for any one individual bet is a case of searching them all. You will also need some luck because just because the odds you see are the best at this time, wait a few hours and there could be better odds elsewhere. OR all odds are cut and you should have taken what you had. It is sensible to bet when the odds offer you value, but trying to find the BEST value possible is a fools errand.
