Miguel's speculation was that stockfish evaluates non draws as draw because it see that it cannot make progress by checks and I responded to this claim and showed that the score of stockfish is never lower than +4 unless you use fail low that cannot be trusted.
I believe that stockfish is better thanks to superior search.
It seems that it has also better evaluation but with the same tree of other programs it could not see a draw score in the root position that is really a draw.
Really stunning endgame by Stockfish!

Re: Really stunning endgame by Stockfish!
Clearly Stockfish's secret is deep search and detection of these types of positions as draw
[D]Q7/6K1/6N1/8/1k6/8/1pb5/8 w - - 0
But may be there are exceptions to the rule?

I'm sorry I had the zugzwang detection ticked on... without it I get the same results as yours in Fritz 8 GUI (256 hash):Paloma wrote:btw. which hash used you? I can't reproduce that exactly. (of course 1 core)
