Negative opinions and the subjunctive (past tense)

Question

Hi, are the following translations correct? Especially, I am a little confused about #2 (and #4), and wonder if "No creo que tú tuviera razón." is right for #2. Thank you.

1. I do not think you are right.: No creo que tú tengas razón.

2. I do not think you were right.: No creo que tú hayas tenido razón.

3. I did not think you were right.: No creía due tú tuviera razón.

4. I did not think you had been right.: No creía due tú hubiera tenido razón.

Answer

Hola Mh
1 is correct, 2 could be:
No creo que tú tuvieras/tuvieses razón  or  No creo que tú hayas tenido razón
3 should say "... que tú tuvieras/tuvieses razón"
4 should say "...que tú hubieras/hubieses tenido razón"
Saludos
