/*AXIOM: The pieces that are not allowed to jump will never take a diagonal as alternative route to reach the endField. They are always taking the straight way.
* The way could be eighter vertical first and then horizontal or otherwise !!
*
* EXAMPLE:
*
* Knight (In this example the piece CAN'T jump) is at B1
* It should reach A3 or C3
* The path to reach those fields would be:
* B1 --> B2 --> B3 ---> A3//C3
* OR
* B1 --> A1 --> A2 --> A3
* B1 --> C1 --> C2 --> C3
*
*
* In case the AXIOM is not guaranteed the path would be: (NOT VALID!!!)
* B1 --> A2 --> A3 // B1 --> B2 --> A3 // B1 --> B2 --> B3 --> A3
* B1 --> C2 --> C3 // B1 --> B2 --> C3 // B1 --> B2 --> B3 --> C3
