What was this game 10?

Who thinks this game 10 of the WCC had some really odd moves by Anand, it really looked to me like he was giving away the point to Kramnik, first why not enter in Nc4 line double attack Q and B and dobling white pawns, even if he saw ahead that line as drawish for black... ok that c4 move in the end Im a real patzer and even I saw it was loosing by force, it just seems really strange to me.
