Here is why you can not believe the PVs engines provide.
All these positions have an eval of less than 1/4 pawn at the root.
But all of these positions are from those PVs:

I don't understand this. A Chess program does a selective search and gets to depth 70. Even if it gets to depth 500 chess is not solved. Selective search means accidentally pruning best moves for it can't search all nodes exhaustively.

I quess You get c4/d4/e4/Nf3 with different tries. BTW note tb access without 6 piece set! Question: if You have more cores does SF search lines more carefully so depth is not increased much?
