It is Magnus Carlsen vs Sergey Karjakin
Karjakin has never even been above 2800. I think he is going to find Magnus a handful. That said, he has little pressure since he is expected to lose. That monkey off an athletes back tends to bring out something extra in a player.
They meet each other in Norway chess in April. Most chess players tread lightly in games before important matches. But I think Karjakin has to give Magnus doubt and put lots of pressure on him right there and then. He has to get himself in the right psychological state from now on.
At the same time all those facts are also irrelevant that's why chess is considered a sport IE it comes down to who is better that day/ tournament.
