...and the Greatest Endgame Player EVER is >

....this person.

He is in rare company 'cuz he is an OTB Grandmaster AND Correspondence GM ! 

....and they say he was the very best at Rook endgames.

Here's a 128-move R+B vs R masterpiece....done in U-50 moves (43 moves....JIT !).

The above endgame should be studied and then restudied over & over for all non-masters.

so that is a picture of Ulf Anderson?

You could find a lot of similar images

I don't know about the photos but the game is legit http://www.chessgames.com/perl/chessgame?gid=1019693

Sorry my phone is so laggy I ended up postinf the same comment 5 times and it's really hard to delete it.

The game against Karpov isn't an endgame. The game never really quite reached the endgame stage.

Wow, that's really tough. 

Every match-play World Champion excelled at the endgame, including Tal. Most World Champions were the best endgame player of their generation. 

Today's best players don't have the advantage of adjournments, and yet they usually play at a higher level than even the best pre-computer endgame players (that would be Karpov, Andersson, Speelman, and maybe Kasparov). 

By that standard, Carlsen is probably the best endgame player of all time. But I really enjoy the endgames of Andersson, Smyslov, Botvinnik, and Karpov. 

Rubinstein, Capa, Smyslov, Karpov, Ulf Andersson, Carlsen
