Boy, what an (unexpectedly) epic battle between Carlsen and Karjakiin. 7 draws to start, then a Karjakin win. Media going ape#### and a lot of mindless extrapolation to Karjakin as the next champ. Ah, but Game 10 had other plans. Kind of a messy one with a missed forced draw early on (that Karjakin would gladly have taken had he seen it). Carlsen had Karjakin cramped into his back three ranks and eventually pushed him in a beautiful example of zugzwang where there was no improving move available.
The live commentary has been pretty good by Judit Polgar, but she absolutely refuses to appreciate or even (in some cases) comprehend what the computer analysis is plainly telling her. I actually like this approach most of the time since anyone can sit there with an engine and call out top lines and minor theoretical advantages, but it was pretty clear that Magnus had built up a decisive advantage and only had to grind it out.
As satisfying as it clearly was to Carlsen (who has acted every bit the petulant child in his loss), it wasn't pretty early on and he again dodged a bullet. A draw in this one might have sunk his chances to retain the title.
Both guys are clearly exhausted at this point. Carlsen was never pushed anywhere near this hard by Anand at any point in their two World Championship meetings. In fact, he streamrolled him pretty convincingly. As Kasparov said at one point during this match, Karjakin is a fine player, but Carlsen is exceptional. I think a lot of people were surprised, though, how well (and accurate) Karjakin has been. He has clearly frustrated Carlsen to this point with his resourcefulness and defense. These two are nearly the same age which is a big change from Vishy Anand as a competitor who looked every bit the 40-something in his previous two title tries. Karjakin's form was obviously very good in the Candidates Tournament (besting a wildly talented field) and it seems to have continued.
The inaccuracies in Game 10 are certainly the result of mental and physical fatigue, but that's how these classical events go. I can't even imagine how tired Kasparov and Karpov were in the (abandoned) World Championship in 1984. 48 games over 5 months with Kasparov charging hard at the end.
Should be an exciting finish in this one. If it goes to tiebreaks, Magnus is about as good as it gets in short time controls and would be the clear favorite.
