As I’m interested in chess history I found the following documentary fascinating. Many people talk about ‘modern’ chess as if it’s cast in stone, yet chess has constantly evolved throughout its history. My take is that it’s now essential to experiment with other forms of the game to diminish the effect of that computers have had.
What could be done to make chess harder for machines? My own preference would be to simplify the game by rescinding the double square pawn advance and abolishing castling rights. This would slow the early part of the game down considerably, and this lengthy manoeuvring phase would put the emphasis back on positional understanding over a knowledge of opening theory.
