The British chess magazine imaginatively named 'Chess' has made a special version of its January 2011 edition available free of charge in electronic format.
It's quite a few years since I had a subscription to Chess, but the quality seems as high as ever. This special edition is basically the round-up of the London Classic tournament which took place in December (the other parts of the magazine are not included in this freebie).
Besides the magazine pdf, there is also a Chessbase file (cbv) with 13 annotated games from the event including Luke McShane annotating his win over Carlsen and Vishy Anand doing the same for his own win against Carlsen.
The magazine can be downloaded from Chessbase here.
