Anand's Bb7 Novelty

Considering the fact that Anand won twice against Kramnik in the following opening, do you think that his line will be considered mainline soon?  Also, what do you believe is the best line for both sides?  Share your opinions about this fascinating new line.

It was a blunder, but he made the best of it :-)

I really would like some extensive Rybka 3 analysis of these games, I just can't seem to figure out the positions myself :D

It deserves the name Anand's variation.

The mainline my opening books gives is 14.Be4 instead if 14.Qe2. It lists Qe2 as a sideline and lists 14...Ba6 as blacks move. I think Bb7 is slight improvement over Ba6, I also think 14...b4 is a playable. Bb7 wasn't a blunder.

I'm relatively new and my knowledge of openings is limited, but Bb7 just seems pretty natural.  I'm surprised it's new.

14....Bb7 may be new at this level but it has been played before. the more usual black moves in this position being 14....Ba6, b4, or Ra5
