I am missing some gold on his profile!
No seriously, I would not call this random counterplay by any means. He knows that the only way we can turn the SA pick into something "useful" for us is to take the thing in 2 turns. Such ballsy expansion is not uncommon, he even does that himself (I could back it up with links but I think we should not discuss the style of players, but positions)
What you are missing there IMO is that Rufus has already one pick which he can't transform into easy income and this is true for Middle East, Caucasus or whatever, even if it's East China.
I did not miss it, I rather see it as one of the few advantages of our picks. Although I am of the opinion that EC is easy income and our position is worse if he has that instead of Cauc/ME/whatever. I always was of the opinion that EC is super strong against Russia, as I pointed out in option C of my pick set, but I guess I am alone with that opinion
