That Carlsen would be beaten by Burn and Spielmann isn't even good trolling :-)
Actually this is kind of counter-trolling. :-)
The primary trolling is suggesting that masters of the past were weaker than today's. Firstly it is disrespectful, secondly nothing proves that (only some dubious computer-generated "data", unfortunately some not-very-bright-minded people tend to trust it) and thirdly there is a reason today's top level declines (I have already written about).
It is utterly ridiculous to say that Carlsen is clearly the best . Today's ratings are flawed. They keep going up and up for top players and are clearly inflated. Again no grandmaster ever won 20 games in a row excedpt Fischer and this streak included 3 top grandmasters in qualifying matches. Fischer was the best and it's not even close.
