Who's your all-time favorite player?
Mine is Mikhail Tal!

I suppose you want just one but I have to pick two. Fischer when I was young and Kasparov now.

Mine would have to be Bobby Fischer. I think I became interested in chess as a result of him. I do not know if I would have become interested in chess if he had not existed. 

Bobby Fischer and Emanuel Lasker.

I like Nomzowistch, Reti, Rubenstein, Capablanca, and plenty of others.  But Fischer and Lasker played like pit bulls pulling down a bear.  They simply would not let go.

Kasparov is awesome.  He may have been the best chess player of all time, and what he does politically is simply inspiring.  You can see " target="_blank">http://www.kasparov.com/ or " target="_blank">http://www.theotherrussia.org/ for more information about this.

What Bobby Fischer did in the first half of his life was also inspiring.  Unfortunately, this is not the case with what he did in his later years.

Tal and Bronstein.

Both geniuses who left legacies of beautiful games.

And both decent men who clearly played chess for the love of it rather than self-aggrandisment  - Tal would play pretty much anybody in offhand games and Bronstein played with graciousness in ordinary open tournaments.

Keres.  Best player never to be a world champion.  His games are fun to play through.  He had a plus record over Capablanca, Euwe, and Tal.  Also had equal records against Smyslov, Petrosian and Karpov.  Also beat Fischer a few times, making him the only player to beat 9 world chess champions.  

I like Bobby Hull as my all time favourite player!

i love the way Paul Morphy played. Very very quick on almost every move and hardly blundered and excellent positional player. Would be tough to see him lose a blitz game.

Alekhine's game are the most fun to  play through for me

I find a lot of enjoyment in going through Mikhail Tal's games. Just when you think the position is becoming simple and slow...WHAM!! A spectacular piece sacrifice that almost ends the game right there. His ideas will amaze me forever.

Tolya Karpov,who else ?

Best player ever,Kasparov being the strongest of course.But Karpov is so gifted...

Best proof of this is that everyone may think they could play the way he does (well did....).That's the real mark of genius,making people think you're common when you're extraordinary.The art of doing nothing

As for Kasparov,he's an amazing fighter for sure and incredibly gifted too,but his dozens of home-prepared wins never impressed me that much.Lots of work,great talent,impeccable physical condition.The "almost perfect" player...

Karpov was his equal with much less work and the constitution of an asthenic shrimp.

I agree. Karpov is also a very strong player. One of the greatest positional players ever; it's a shame he's not active.

It would have to be....

BIGDOUG!!!

Hi is active, but not so much.

I would agree that Keres is a very strong player, but no one played with as much determination as Korchnoi.  Playing two world champion events while your family is in prison against arguably one of the strongest positional players of all time is a feat unto itself.  That is why I give the slight edge to korchnoi, but also do not wish to say that Keres was any less of a player.

One overlooked grandmaster was Vladimir Bagirov.  He coached both Tal and Kasparov.

Fischer is in my opinion the greatest, but my favorite is probably Bent Larsen.  He was one of the top 3 or so players in the world at his peak and he still liked to play unusual surprise openings!
