Ask Lemmygrad

Dear comrades,

As we all know there are two soviet eras pre and post death of Stalin. We all know Khrushchev basically did a coupe detat, by killing all Stalinists and also by starting the anti Stalin propaganda. We know he was the cause of the Soviet Sino split.

But what exactly caused the split? What policies did he push that were reformist or capitalist in nature ? How exactly did he fuck up? I know the results, but I lack in knowledge of the causes.
