I feel weird doing a 'well actually' in a post about something so serious and sad, but it might be worth pointing this out to prevent someone from getting the wrong idea about their chess strength: the meaning of '1400 online' varies greatly depending on the site and the time control. According to https://chessgoals.com/rating-comparison/, Chesscom blitz 500 = Lichess classical 1400, and chesscom blitz 1400 = lichess rapid 1880. (I don't know how accurate that site is, but the general point is definitely true; AFAIK Lichess and Chesscom use different rating systems with different means, and within each site the strength of the player pool varies across the time controls.)
