Age 16, the end of serious chess for me:
After we played in a chess tournament, Yasser Seirawan (my age, but brilliant) joined me, the only other teen, for pizza. He walked through our game in detail. He remembered every move (I didn't) and explained what I’d missed.
"You could be a lot better if you studied another four hours a day and gave up minor distractions, like girls."
Study my own games. Study other games. Study openings - book learning. He shared great advice.
I enjoyed the game. Not so much the price tag.
I stopped playing tournaments and focused on other pursuits.

The last chess game I ever played with my dad was the first one I won. I was 13.
He didn’t announce he was done. He just stopped offering.
I still think about how small a thing it takes for an adult to end a ritual a kid is counting on. With my own children I live by the opposite rule: when they beat me at something, we play again sooner, not later.
Not a dunk on Dad. He was a great father, just not perfect.
