It's easy to answer why Bb6 was played, but not easy to handle. It puts
a minor piece on a protected outpost, and prevents black from playing b6
to get rid of the doubled pawns. This is the computer way of looking at
things. The human view, I think, is that the bishop is creating very
little nuisance on b6, the doubled pawns are not an urgent issue, and
white needs the bishop to protect d4 and the king side. The only piece
that can take back the d5 square is the knight, and the bishop should
take its place protecting the king-side. I think the move should be Qc2
to leave d2 for the bishop.
This kind of reasoning is beyond what I can code into a program right
now.
I'm not sure it's such a big error. The king side can be defended, and
black's pieces also have limited mobility. Junior found the right
approach to the position by not hanging on to d4.
