When I was about 7 years old my uncle taught me how to play chess. If I had to estimate his strength at chess I would say he was about a 1500-1600 player.
He used to beat me at chess a lot when I was young, but gradually I became stronger over the years. We would play chess off and on for 10 years over the holidays, I probably played against him 100 games.
In the 4th grade, when I was 9 I remember beating a bunch of other kids at chess during recess on rainy days (I brought a board in)
Eventually my uncle became sick, and I remember the last game of chess I played against him he resigned, but I declined it... He was like wtf? he was down a minor piece and wanted to call it quits, but I didn't let him resign b/c I told him he had a winning game. So he looked at the board for about 20 minutes and could not find the correct line, so I showed him it (it was sacking his queen for my knight then my queen would be hanging the next move, and he had a passed pawn I couldn't stop after that)
A month or so later he passed away, and I stopped playing chess for about a few years. I started playing chess again vs my computer, and then eventually on chess.com
