Hello Mr.Alex.

I was thinking about this puzzle again.

The "liar's" answers to the questions are accurate, right?
When we ask him if he's the accurate truth teller, he is (because he's always telling the truth), but he thinks that he's not, but then lies about it and says "YES" (which again is true).

Am I right?
What do you think?
