Who is the greatest pro chess player of all Time?

Its for sure garry kasporov. 

Bobby Fischer maybe?

Or Hikaru

hikaru is good but the best no

I do like bobby though. I want to see him fight garry

Viswanathan Anand

the greatest of all time. I almost positive he lost the world title to magnus

Magnus Carlsen, Jose Raul Capablanca, Paul Morphy, Mikhail Tal, Mikhail Botvinnik Fabiano Caruana...

You mean  Viswanathan Athad?

Capablanca yes but mikhail tal no. The reason for that people started learning how to defend so he stopped winning.
