Stockfish 6 on my machine can't find it. It's amazing how stupid these engines are. And I should use them ?

Can't find what?

Henk, your randomizer works great!

Best move. Or are they going to tell me that best move is the move that Stockfish gives and that grand masters are wrong.

Engines are statistical, not intelligent. So most times they will give you a better move than a GM, and less and less times will be the other way.

In case position is theoretically very important that may not be enough. In this case it is not. But I don't trust positional play of chess engines (anymore) for it is certainly not the first time.

Perhaps waste of time ? Just like Fortresses, KkNB end game, perpetual check detection and .... ?
Even not reducing all moves of a bad placed knight won't work for Skipper in this position.
