Conditional sentence type 2 refers to an unlikely or hypothetical condition and its probable result. These sentences are not based on the actual situation. In type 2 conditional sentences, the time is now or any time and the situation is hypothetical.
If the weather wasn't so bad, we would go to the park. (But the weather is bad so we can't go.)
If I was the Queen of England, I would give everyone a chicken. (But I am not the Queen.)
If you really loved me, you would buy me a diamond ring.
If I knew where she lived, I would go and see her.
But what about this sentence "If I told you that I lived in Russia, you wouldn't believe it."
How to explain it under the rule of conditional sentence type 2?
I suspect conditional sentence type 2 can be used to express other things not just "hypothetical situations".
