There's a 'fog of war' variant where you can only see the squares that a piece of yours could move to.

  --that a piece of yours could attack, I believe, not move to

    I just checked and if you want to be technical it's "move to normally, could move to during a capture if a piece was there, or holds a piece you could capture". Pawns are the only case that where those three are different but they see all three: - directly in front (move) - forward-diagonal (normal attack) - horizonal exactly only in the case of a enemy pawn moved to that square last turn that can be taken en-passant (capture). That square goes dark if you move another piece.

  That one would be interesting to try with AlphaZero. Reinforcement learning systems tend to have trouble with imperfect information.
