Hi,
Lets suggest good site with real tipsters with good knowledge of the game.
Sports like tennis, basketball, hockey European soccer etc
Most tipsters you will see here will just drop their picks with no analyzation involved. Up to you if you will follow it or not.
If you want to read some analysis, you can use your favorite search engine then put the keyword
"(name of the upcoming match + predictions)" or something along those lines or joined a specific thread discussion for the sports you preferred to bet.
Any websites will do and from there, you can make a comparison. But I'm not an enthusiast of reading other's analysis as I have my own way
(only to the sports I have knowledge).
