I'm first time here and therefore, I don't know whether this question is eligible on this site or not. Let's see the following sentences.

What is the difference between these two conditional clauses. I'm asking this simple thing because it's confusing me, since there is no such thing in my native language (it's quite different than English).

If you saw a lion in a thick forest, what would you do?

and

If you were to see a lion in a thick forest, what would you do?

I can understand this one (It may be a different question).

If you had seen a lion in a thick forest, what would have you done?

but it's a bit confusing me. In my native language, it's always formulated as follows.

If you would have seen a lion in a thick forest, what would have you done?

Does this make any difference in English?
