His rating record, that is.
After round four of the London Chess Classic, Magnus Carlsen has reached 2857.4 on the live rating list. The former all time record is 2851 held by former World Champion Garry Kasparov set in 1999.
Here is a snapshot of the live rating list as of today (6th December 2012).
We may argue that 2851 in 1999 is worth much more in today's rating due to rating inflation. Many have argued on the issue of rating inflation over the years. Of course this is quite a pointless argument.
I'm just wondering what will be Carlsen's rating at the end of the London Classic.
