Position after 47…a5. White’s position is overwhelming. I expect Magnus to score a full point soon.
Magnus blundered to allow Cheparinov to draw but he gave back the favor and now it should be over soon. I suspect that the 30 second increment time control has to do with the blunderfest in this game at the end.

Fantastic Magnus!
According to the tablebases this endgame is non-trivial!!
59.Bg2 was the only move to win for white. After 59.Kb3?? Ke4!!
(only move) is a draw according to the tablebases!!
Magnus has won!
Carlsen-Topalov becoming a reality…
What’s tablebases?? If some computer rubbish, why would you trust it? Remember Fritz 10 can’t see all mates in two moves?!?!
Carlsen did it !!!!!! scary kid !!!!!
nalimov endgame tablebases cover all endgames with 6 pieces or less.

A tablebase is a structured database that solves chess. At the moment tablebases for 6 pieces including kings, exist. That means that chess with 6 pieces is mathematically solved and perfect play for both sides is known explicitly.
See for example:
http://www.k4it.de/index.php?topic=egtb&lang=en
here is a quick tablebase analysis:
57-g3?? (57.-Ke4=) 58.Bf1?? (58.Bd5+-) e5?? (58.-Ke4=) 59.Kb3??
(59.Bg2 +-) Kf4?? (59.-Ke4=)
60.Bg2! +-
Five blunders in a row!!
Five blunders in a row, but in a highly uncommon and unbalanced game. I would not call these blunders at all.
I feel the problem is the time allowed for the game. The players simply run out of time and they are left with no time to figure out the correct move. Blunders are then made. I am sure with more time both sides would have eliminated some of the blunders.
The fast time control gives the advantage to the younger person with the faster calculating skills. The older player who is naturally slower in calculating is put at a big disadvantage.
for some pretty good commentary on the game. you will find it here at chessdom.

“blunderfest” is a highly inappropriate description of the game. All the way up to where you can doublecheck against tablebases it seemed to be very tense and only small inaccureacies allowed Magnus to gain an edge.
Then in time trouble there were moves that were incorrect according to the tablebasese, which then necessarrily means giving up at least half a point. Yet at least to the most of us the erroneous moves were not clearly wrong or goss oversights – they were simply moves that can be proved wrong given time and computing power – something that were available to none of the players at the time.
Maybe Susan is preparing a
big come-back to show them all
who is boss?:o)
I mean something has to be done!
These guys blunder all the time.
Anonymous @3:14, ditto!!! It seems to be a global sport problem (the blundering that is). When I was a kid, I remember what an excitement it was when the figure skaters fell on the ice or the gymansts drop the ball or… nowadays whoever manages to fell on the ice becomes a champion. 🙂
… or maybe now that we have computers we see chess “blunders” that have always been part of the games but were not perceived as such?
An incredibly exciting, sharp game. The key move seemed to be Chepa’s 19 … Nd4. This move offers the N as a sacrifice, but Magnus recognises it as a trogan horse and declines the gift. Instead, Magnus piles on the pressure to later fork the same N and a B with 25.f5. But amazingly, Chepa had seen far enough ahead to see that by move 28 … Qxe5 he will have restored “equality” (Black has R versus White’s B & N). These complicated games must really tire the players.
