HiQ应用中的可变范围问题

I think I have a global variable scoping issue with my java program. It's the HiQ game and I have a board object to store the state of the board, 1 is peg, 0 is empty hole, and -1 is invalid position. The game creates 32 boards for the possible moves and builds out the possible moves and goes down into a depth first search to locate a path to get to one peg in hole 3,3.
