Do super grandmasters make mistakes?
You bet they do. We saw two astounding blunders on the highest possible level in game six of the world chess championship between Magnus Carlsen and Vishy Anand.
So if world champions make errors in slow games, you can bet that super GMs make all kinds of blunders in blitz games, even as strong as they are.
GM Roman Dzindzichashvili shows you blunders made in a game featuring the second-best player in the world, Fabiano Caruana.
