Russian Blue and Korat cats are similar indeed, but they do have differences. I'll try to make a table for you..
Moreover, the head structures of the two breeds are quite different and they also have very different personalities. You might have read about it in the articles.
Russian Blue cats
As to their personality, Korats are more companionable while Russian Blue cats are more independent and less demanding. Russians can be let outside, which must not be done to Korats for their own safety's sake.
Anonymous:About 10 years ago, when my sister and I were too young to pay enough attention, we got two half-breed kittens from a friend whose parents were breeders. Their queen got out while she was in heat, and so they gave away the litter for free. I would swear that my sister (she's older than me) told me that the queen was a Russian Blue, but now I'm not certain - the one I kept when I moved out has the classic heart-shaped face, more golden-toned eyes, and stockier body of a Korat, and will follow me all over the house and pin me down in various uncomfortable positions all night, but he also has the thicker coat of a Russian Blue and shies away from ANY strangers. Would I be right to guess that he most likely got the thicker coat from whatever his father was, and really is a half-Korat? I don't think it matters too terribly much, but I am curious.
It's difficult to say without a photo. Considering it was only half-bred, anything is possible. Sometimes the Russian is pretty similar to the Korat but not the opposite.
A few more details about the head structure:
Russian Blues have longer faces and large, pointy ears. Korats have more foreshortened faces and smaller ears.
