Celticjim:The bug was used on my opponent’s move 76. He moved b4–b3, capturing one of my pieces after his piece had moved b3–b4 on the previous move.

Further information (I am not worried about my opponent knowing this information, there is no way he can use it to his advantage).
My opponent has 2 movable pieces left, either of which could capture any of my remaining movable pieces if given the chance.
None of my remaining movable pieces are capable of capturing either of my opponent’s movable pieces.
My opponent’s HQ is on a1, now protected by only one bomb on b1. I have no sappers left, so I can ultimately only approach the HQ from one square.
My HQ is protected all around it by bombs and my opponent has no sappers left.
The only way I can force a win is to get around his pieces and capture his HQ, the only way to do that (assuming perfect, legal play from my opponent) relies on my opponent not being able to move a piece back to where it just came from.

So if my opponent continues to be able to exploit this bug, I will not be able to win, but I would be able to if the rules are followed. Because of this, I will not play another move in this game either until Fencer intervenes, or until I am about to time out.

And in reply to your edit, if I could edit my previous post I would but, as a pawn, I cannot. My browser automatically converts it to a link anyway, but for the benefit of others, here is a link not surrounded by brackets: http://81.91.83.6/en/ReadBug?bgi=1995
