Human Chess is a chess variant where playing the top engine move is forbidden
It's a cool concept but the first naive thought that comes to mind for me is that white could just easily dominate by taking advantage of the fact that taking a queen is almost always the top engine move. So just by maintaining relative king safety on white's side, you just open your queen early and make sure that every move there onwards hangs your queen in some fashion. It's very easy to hang a queen. You just have an invincible juggernaut for the first half of the game until you've demolished enough pieces to make it hard to find ways to hang your queen, and by that point the material advantage is such that the opponent might just resign.
