Have loved chess since I was a kid. I made my first set by drawing pieces on paper and taping them onto checkers in a (successful) bid to guilt my dad into buying a real chess set. Also had a fascination with red chess pieces as a historically alternate color. Even more so after reading "Alice Through the Looking Glass" with the Red Queen. Was originally going to roll with "The Red Knight", but that seemed cliche as all heck, so I went with "The Red King". By the time I realized the name might come off as arrogant, it was too late, it had already stuck.
That's why my initial avatar here was a red crown (the typical symbol used in chess for the piece), but as noted above realized that could be seen as arrogant for anyone that missed the chess connection. So I swapped to my current one. Not the most exciting, but it works. If I do swap it in the future, it'll be for something equally clear.
