I do not like 14.dxc6 that is suggested by Fritz8's main line but I do not find convincing alternative for white. It may be interesting to see what programs play with white after 13...Bb7 but unfortunately I can find no win for white after that move and it seems more and more to me that Junior had good drawing chances with Bb7.
