What do you mean by "big advantage"?

"DarkThought WCCC'99" knows about White's unstoppable passed Pawn
on h2 and it also knows about the potential breakthrough of the
two Black Pawns on e4 and f4. Both somehow cancel each other out
in the static evaluation such that the overall score is just the
+1 material advantage of White.
