The kids all prefer blitz and bullet. I seem to remember some longer time controls way back when, but my memory being what it is...Luckily there is a solution; join a slow play club. I'll give you the link to the most popular, but there are some smaller groups as well. Have fun!

Until the current pandemic, I played exclusively over the board, generally in multi-round tournaments with classical time controls, e.g., one game a week on Thursday nights, for 6 weeks.
Now, with over the board tournaments on hold, I find myself playing on-line. But it seems that whether on chess.com or its competitors, Tournaments with classical time controls are Few and far between. Almost everything is rapid, blitz or bullet. I imagine they are popular because, amongst other reasons, you can have an entire tournament over the span of a few hours. But it’s a very different game, and I much prefer classical controls.
Am I missing something? Any suggestions?
