Is it just me or has the quality in this World Championship been at a slightly lower level than in previous times? Some inexplicable decisions and oversights in quite a few games. Still can't get over Magnus being unable to convert some of the advantages he built up in earlier games. Granted Sergey has shown he's the premier defensive player of this era, but still...
While Broken and I were watching game 10, we both saw a forced draw was a possibility. Ok I'll admit when Sergey missed it, I assumed that I must have missed something only to see Svidler show that it was indeed a forcing sequence. The fact that both of them missed it is telling. Remember what a big deal we made of that game in the last World Championship when Anand missed a chance to gain an edge (I don't think it would have led to a clear win, just a dramatic turn around of the range of possibilities for that game). Seems that has happened with more frequency this time around. Maybe I'm being harsh, sure feels that way though
I don't really agree that it's been worse. The game you're speaking of is game 6 of the Carlsen-Anand match in 2014:
http://www.chessgames.com/perl/chessgame?gid=1778864 Anand missed 26. Nxe5 which would've led to a winning position or damn close. That would've made things extremely interesting in the match last year. And then there was the ridiculous 28.Nf1 in the 2013 match :
http://www.chessgames.com/perl/chessgame?gid=1737896 Those games are worse than any we've seen so far in this one. Overall Anand was pretty easily outmatched last year, he can't defend well enough anymore to really hold the tough positions. The year before was even worse, Anand put up no fight and was just inaccurate throughout, ,making it a walk in the park for Carlsen. I think coming into this match the expectation was Carlsen would win a couple games and Sergey wouldn't win any and that it'd be fairly comfortable. Against Anand you got the sense Carlsen might lose a game or two but he could win 4 or more pretty easily.
The game yesterday was interesting because it featured two clear mistakes from Karjakin. The first was a calculation/tactical error where he didn't see Nxf2+ led to a clear draw. Also, the main reason this was a huge mistake is that a draw would be an awesome result for him given he's up a point this late. So the move wasn't necessarily a big mistake under normal circumstances, but clearly it was here. The 2nd was just a positional blunder where he didn't realize he needed a rook on the 8th rank to defend his position. Still it was a great game from Carlsen. The game before was all around a good game even though Karjakin missed Qb3. The real atrocious game was the one Carlsen lost. Karjakin missed many wins throughout and Carlsen seriously played like a bloodthirsty amateur who had no idea he should be playing for a draw instead of recklessly pushing pieces. There have definitely been some errors aside from that, particularly the real poor white game from Karjakin that Carlsen was unable to convert, but most individual mistakes have been pretty small, there just have been some games with a bunch of inaccuracies. IMO, that's still higher quality than having games with an enormous blunder like some of the games in the Anand matches.
We have to remember these guys aren't machines and they aren't always going to play like one. With so many people following these matches online with a program it makes it seem like the players are hacks because they often miss the computer's #1 move.
