I would not be surprised if Junior 6 chose the move for all the right reasons.
However, a +1 pawn evaluation is hardly convincing.  In fact, I see computers
think that they are up one pawn in gambits all the time, only do discover they
are about to get the tar smacked out of themselves.

Since Junior seems to be at or among the strongest computer programs in the
world at tournament level time controls against other computers, that indicates
(to me) enormous tactical ability.  Therefore, I suspect that Junior "knows what
it is doing."

On the other hand, it may be accidental.  We will never know unless Amir cares
to tell us what is going on with this eval.
