Yes, if you place the number as your absolute reference, Junior has only 1
advantage pawn. But, and now I remember some words of Thorsten Czub, other
important references exist in these analyses of Junior6:

1. The presented pv is winner, that is to say, none moves done
   for Junior allows the blacks to draw the game.
2. That's no initial move that can to substitute 1 ...b2.

These 2 observations, take me to end that the given evaluation
by Junior in this position (1 pawn), doesn't have the dimension
that seems to have.
