If you're ever going to get the point where you recognize tactics (or anything, for that matter) on the board, how the pieces move must already be internalized and not require any thought. People even especially practice visualizing knight journeys between arbitrary squares to make this more automatic.

If you ask an experienced player to use a weird piece set, you will only be introducing error and cognitive overhead. If you ask someone naive to the game to use the piece set, do they internalize how the pieces move more quickly and get over the impedance when they start to use a normal set?

Going at a tangent to your idea, maybe it is possible to construct a set that aids the performance of a naive player, but which degrades the performance of a more experienced opponent. Could that handicap be as great as a club player offering pawn odds against a naive opponent?

Exactly this. Relatives have been trying to choose "fancy-looking" chess sets for me as a gift, and I always hated them. I don't want fancy pieces, I want the standard ones that don't give me cognitive overhead :-).

"Tournament chessboards" are my favourites, obviously.

Hell is filled with glass and ornate chess sets, I am convinced.

I've gotten so used to 2D knights that it annoys me when people face them forward on a 3D board.

There are flat chess pieces that have the traditional 2D symbols on top. Another question is whether anyone makes 3D knight pieces that are designed to lay flat on the board. Such pieces would fit a "Godfather" themed chess set rather well...

Blindfolded chess for the better player ;)
