Of course Dostoyevsky wrote Notes from Underground in Russian, a language I do not know. But I guess the translator could have chosen either, since they seem very nearly identical.

I'm not familiar with the book, but I can think of one possible situation in which "That, you probably will not understand" would be preferable.

Suppose Ivan and Natasha are talking about various subjects. It's clear that Ivan is more experienced in life, and the conversation is mostly Natasha's asking about many different things. At some point, Natasha asks about one particularly difficult topic, and Ivan's response is "That, you probably will not understand."

I'd add the red comma because the sentence doesn't start with the subject, but the object.

I think the difference is that emphasis is placed on the subject in the first and the object in the second.

I've checked the book. It says "Вот этого (= that), наверно, не изволите понимать."

The word order is different. Raskolnikov's alternative and unusual word order places the reference word That (the object of the verb understand) in focus. In speech, there would be an emphasis on this word at the beginning of the sentence, unlike if it were at the end.

I'd add the red comma because the sentence doesn't start with the subject, but the object.

Well, that's a reasonable way of thinking but it's really not necessary here. In fact, it reads better without the comma.

Svidrigaylov, here is another example of putting the object first for emphasis. I suggest that you refrain from doing this in conversation, for it is very strong and could be unnecessarily offensive.

James: Why didn't you invite me to your party?
Mona: YOU, I don't like! (I used a comma to signify a pause in conversation.)

In a less serious vein, native speakers sometimes use inversion for humor.

Mona: Would you like some of these delicious cookies?
James: Haven't you noticed my [big] waist? COOKIES, I certainly don't need!
