I am 59 years old and I grew up without computers,calculators,chess computers, programs,and engines,and I don't use them and I appreciate it if you did not use them when playing me.Any chess books, notes, or moving pieces around on a board to see how positions might evolve into if certain moves are made,such as RedHotPawn's "Analyze Board", which I also use, or a chess friend's advice, these are fine with me for you to use, as it helps you to learn and improve your game, and to have fun.
