I have heard of this bug bug experienced myself in one
of my games.  The quoridor program does not allow one
to make a move that would make it impossible for ones
opponent to reach his goal but has no problem letting
one make a move that leaves oneself no way to reach
the goal.  Unfortunately at this point the opponent
has no move that would be considered legal and he has
to forfeit.

Hmm. This shouldn't be the case. IIRC, the game only does the pathfinding
stuff (i.e., checks if there is a way for the opponent to reach his goal)
after you put a fence on the board, and not after moving your pawn. So pawn
moves would never be illegal, even if your opponent is "trapped"  -- unless,
of course, you try something stupid like running into a wall or moving off
the board.
