Yes very difficult to Stockfish:

Analysis by Stockfish 1.9 JA 64bit 2CPU:

1...b5 2.Bb3 b4 3.Nd1 a5 4.Ba4 Ra6 5.Ne3 Be6 6.Nc4 Rd8 7.Kg2 Bc8 8.Rh1 Be6 9.Re3 Rd7 10.Rg3 Rd8
= (0.00) Depth: 36 00:16:28 2058mN
1...b5 2.Bb3 b4 3.Nd1 a5 4.Ba4 Ra6 5.Ne3 Be6 6.Nc4 Rd8
= (0.08) Depth: 37 00:30:57 3894mN
1...b5 2.Bb3
= (0.16) Depth: 37 01:11:47 9161mN

I played six games with 40/10' level with fast white wins everyone.

I am pretty sure that R4 or most of the other top engines will get a totally winning position very quickly. The evaluation of an engine is more to steer play into a certain direction rather than giving an exact final outcome. I would worry about this if one of the top engines would not be able to convert this with best defense on the other side. I tried a few lines but was unable to hold as black, and within a few moves things became decisive. I guess it will be a while before you get an exact evaluation output, and if you watch many engine games, you will sometimes know that a +.45 advantage in a middle game where the other side is passive has a much higher probability of a win than a + 1.5 advantage with 2 rooks and a pawn or with opposite bishops and minus a pawn.

I understand what you are saying but I must say I strongly disagree with the enlarged statement. Or perhaps I misunderstood what you are getting at ? I believe that engines not unlike humans need to be able to assess the given position, and see the truth. Here they clearly do NOT!

For example, in this position alot of engines feel black is better and this is completely wrong! There is a clear winning plan for white. If the engine cannot see the final outcome from a set position (seeing it is lost) then it may be inclined to allow this position (black's pitiful position) in the first place. So I believe that whether or not they can win with the white side of the board is irrelevant as they may have allowed it to occur in the first place.

After three hours, Stockfish-1.9.1 (8 threads) is now beginning to favor White. The program is still running, so I'll provide an update later.
