Last update 13 May 2025.
The introduction (what I originally planned to do, though I later amended this).
Suitable for young players (with adult help)
My test for inclusion here: would I (as a fairly peculiar child) have enjoyed playing with this when I was12? My parents were useless in these areas, my teachers were worse, so I played, and teased out stuff. I just wish I had had pointers to some of these ideas, back then. Young players don't have to stick with this easy set, but some of the stuff in this blog is pretty advanced, because I take no prisoners!
Still, this set is a good place to begin:
