I have always worked in 2 way infinite tape and most probably I think that was the first represented as Turing Machine. How can I emulate One-way Turing Machine to Two way Turing Machine.

How to prove that One Way infinite tape Turing Machine is Turing Complete?

As you know, the procedure cannot be to somehow specify at the start how many leftward squares you will need. You know that is impossible. Rather the procedure is to treat just the actually-even-numbered squares to the right as if they were all the squares on the right, while you treat actually-odd-numbered squares to the right as if they were to the left. Is that what you meant by "folding"?
