Apparently, these rules were NOT CLEAR to some of the participants!
Rules are not absolutes, in all cases, and this case is a mess, there can be
no other ruling in this case, it's too late!

I consider all possibilities, and have come to the most sensible conclusion.
When you and the others can see through all this obfuscation, you'll see why!

I'm sure if I delve far enough I may find something that vindicates Shredder
completely, and imagine the arguements that would have been made if Jonny drew!
Remeber, Shredder had a Forced Mate, and I'm willing to wager Jonny saw it as
well, before the repeated moves! If that is so, the game should have ended,
unless there was no forced mate, but there was.

I'd love to have viewed that game live, with readouts!
