I found that the sunfish bot on Roblox Chess will always play the same move in response to a move you play against it. I also found that the way in which it is programmed is heavily flawed, especially after I beat it in 14 moves because it blundered checkmate in 1. Because of this, I got the idea to try and speedrun beating the bot after I found the quickest checkmate line. Upon analyzing the flawed ways in which the bot is programmed, and the ways in which it would just blunder checkmate in 1, I found this very easy to remember checkmate in 6 line that will work everytime. I am very sure this is the fastest checkmate line. However, if you discover other mate in 6 lines, or even lower somehow, I'd love to hear about it!

3DS went red middle of first recording, which meant it would shut off in about a minute because of its weak battery. Had to do two separate recordings which are linked below.
