    I got 1.d4 as the move right away. I toggled a button and then it had an arrow pointing the white pawn to 1.d4 and it said depth 45. Maybe I just don't know how to do it properly. Anyway, I know that Stockfish 8 put 1.d4 in the top 2 in the past (though I know that 1.Nf3 came in first).

    Phoenyx75: U speak about the standard chess but that's right. Lichess chooses 1. d4 with evaluation +0.1 at depth 45. The evaluation is taken from the Cloud of chess games. It means that it was calculated previously. settings.pnghappy.png
