I now understand that the strategy I had used for the '12-Coin Problem" (when I had nailed it at age 10 or 11 over half a century ago) was like so:
Step A of strategy: When I tried one way, I gained ground.
When I tried another way, I lost ground.
Step B of strategy: So I chose the way that helped me gain ground.
Step C: Again, I found that, - -- when I went one way, I gained ground. - -- when I went the other way, I lost ground. Once again, I chose the way that enabled me to gain ground.
REPEAT from Step A. (ad infinitum if required).
The problem was solved!
