IGS ranking = KGS ranking

[shapenaji]

I haven't played that much on IGS,

But, I'm at 4d KGS right now (which is taken to be unusual by some given how most AGA 6d are 5d on there. And my record as a 6d AGA is pretty good)

I've played a number of EGF 4d-5d and Chinese 4d-5d, and based on the results, (as well as their estimation) I'm Chinese 4d, EGF 4-5d (though technically, in the EGF database, I'm like 2580, but that's an artifact of insufficient data)

So... I think the evidence for KGS 2d = EGF 4k is pretty slim... but there are huge regional variations in the EU. (It's not even worth trying to use ranks to gauge the handicap with a Finn, just play even and see what happens)

On average though, there is not a 6 rank difference between any of the rating systems, and if you are experiencing it... it's probably just you.


The other thing to consider is the "style" of servers. Certain servers can be beat by a particular style. (The secret to ORObaduk seems to be to play a solid opening and then beat them up with their overplays)

I have found this to comparison on sensei's library to be fairly accurate.
