LoyceV: I've read all those pages and there is only clues how to solve the puzzle and my questions are not about how to solve it but how to create private key and how to transfer BTC using private and public key. I assume that those questions are in the correct section of this forum.
It's a puzzle. The answer can be anywhere from a location, a phone number, or indeed a private key. Handling private keys is just basic Bitcoin, import
(or sweep) it into any wallet and make a transaction.
How about you solve the puzzle first?
