Here is another example for the huge positional score of chess programs(probably also includes IvanHoe that I did not install in my computer and at least it includes robbolito0.09w32 and houdini that gives more than +4 for white at depth 1 when the program cannot see the promotion by search because it is hidden by a lot of checks)

Toga1.2.1a gives 1.17 for black at depth 1 but toga is inferior old program
and I believe that all the programs that are at the playing strength of Rybka3 or higher give a big advantage for white when they search to depth 1 inspite of nominal 6 pawns advantage by black.

[D]7k/PP5p/2PP3p/7p/7p/7p/6r1/K7 b - - 0 1

it's black's turn to play in your fen, and it's very obvious that black has an unstoppable passed pawn on h3. the eval should already return a big score for black without even a search!


White has more advanced pawns in the 7th so black pawn in the 6th with turn to move does not help to prevent promotion with check.
