Chatting with a colleague we came a cross a dilemma (as we are not English native), which of the following sentences are wrong? Why?
- If I knew everything, I'd be a genius.
- If I know everything, I'd be a genius.
- if I know everything, I'm a genius.
The 2nd should be wrong, as with the present I should use either the future or the present, in fact the 3rd seems to me correct, in fact the rule is:
The Zero Conditional is used for actions that are always true when the conditions are satisfied.
So to form this particular condition I use this form:
If + Present Simple, + Present Simple
Am I wrong?
