You may be familiar with a particular video which caught the attention of many chess fans.

The Rarest Move in Chess
https://www.youtube.com/watch?v=iDnW0WiCqNc

This video is extremely well made and went through the many intricacies of chess notation. One part stood out more than the rest though.

Over 1/3 of all possible moves had never been played before! 
Now I want to play all of them so that the number of un-played moves is 0.
Granted he only used LI Chess data but he analysed over 5 Billion games of chess. 

The conclusion to the question of "rarest move" was standardised instead of specific. 
E.g. Bxmn where 'm' and 'n' represent any letter and number respectively instead of a more specific move that we are all use to E.g. Bxe5

He also showed a list of all unique moves in chess and scrolled through them all really fast saying "there's a LOT," which is true, because I went on a crusade to figure them ALL out.

Take your guesses!

Twenty-Seven-Thousand-Nine-Hundred-And-Fifty-Four

And I have written them all out by hand in a google sheet here.

The process to figure out all legal chess moves was actually quite interesting as some moves at first glance may look possible but actually have no legal way to check/checkmate the king. 
Of course I have probably missed a few but I have spent an uncomfortable number of hours on this spreadsheet so I'm pretty sure I'm close.

Call to Arms!

I will write a more in depth process of my thought process behind the moves soon but for now if you would like to help document some games to be archived for the years to come join the discord here -> https://discord.gg/yS4MbwgSbZ <- every unique move will have the associated game attached so You will be remembered. 

I plan on playing chess until this spreadsheet is 100% green and hopefully I will improve along the way. I'm looking forward to the challenge and the community that will come with it.

Thanks for reading and comment your thoughts on my goal,

What a cool idea. I'm going to have to read it through again to make sure of what I'm committing to but on first read I'm kinda hyped up. I'll need to check out discord too.
