Who is the greatest chess player of all?
Stop with this already.
it seems that this topic is posted everyday.
It's akin to, what's the best food?

There is no such thing as a "black and white" answer...
or put it in this way, nothing is in black and white.... you should know, you got it as your name ! lol

This has been discussed hundreds of times in this forum, so i am sure that you will find numerous posts if you just do a search in the forum. Anyway i can give you some names of great chess player.
Bobby Fischer and Kasparov is considered to be maybe the two greates chess players ever lived. Ho`s the greates, we can never decide. Other great players is: Tal, karpov, Spassky, Morphy, Capablanca, Nimzovich, Steinitz, Lasker, alekhine, Rubenstein and many many more. Hope this helps you.

I agree, there's no point in making the same post over and over again unless you want to discuss an interesting twist on the question, such as 'What constitutes the 'greatest player'?'
I have discussed this before but I've never gotten a set answer.
