The above line does NOT change isOver variable.  Try again.  By the way,
it's not usually a good idea to use the function name as a local within
the function, even though it'll work.

This function is still buggy.  It does not return either True or False
if the selected row is non-empty.

How is the following function body any different from:
return self._gameBoard[row, col]

How are the four following lines any different from:
self._gameBoard[row, col] = self._currentPlayer
