One more option than usual ....

A pawn is placed on the lower left corner square of a standard \(8\) by \(8\) chess board. A 'move' involves moving the pawn, where possible, either

  1. one square to the right,
  2. one square up, or
  3. diagonally (one square up and to the right).

Using these legitimate moves, the pawn is to be moved along a path from the lower left square to the upper right square.

How many such paths are there?
