So I was just wondering who is the player on lichess who has beated big guys while having a relatively low rating, a GM killer hopefully.
I came up with this ratio in order to try to figure it out:
Pick up your top 5 victories against high-ranked opponents (I personally focus more on rapid, but you can do it with any time control). After that add all of their ratings up and then divide it by 5.
Now divide that number by your highest ever ranking in that particular time control. A higher rating of big guys beaten will end up in a higher ratio, and a lower own highest ranking will end up in also a higher ratio, thus regarding players who have beaten high ranked opponents while maintaining low rankings themselves as the big guy killers.
I'll pick rapid time control for this.
my best 5 rated victories are : 2078, 2025, 1948, 1932, 1924.
So I'll average those: (2078+2025+1948+1932+1924)/5= 1981.4
My highest ever ranking in rapid is 1694.
So the ratio is 1981.4/1694 = 1.1697
So there it is! Let's find who's the big guy killer!
Ps: Specify time control please.
