I'm writing this in response to Caleb Durward's tournament report about a recent PTQ from which he was disqualified for collusion. You can read his report here (and I suggest you do), but it basically comes down to this: Caleb thought he was properly skirting the rules regarding prize splits and concessions, and those of us around the competitive scene know there is an art to this.
It turns out, the judges disagreed, despite being present for the entire thing. In the end, Caleb was DQed but the head judge didn't recommend a suspension. Even worse was that when Caleb brought up the issue with a Level 4 judge who seemed to indicate that his way of handling it would be okay.
Either way, it's a thorny issue. And really, my problem isn't so much with people trying to work around the rules so much as it is having a non-clear rule in the first place. There really shouldn't be much room for making judgment calls, in my opinion. Either people follow the rules and can figure out prize splits/concessions, or they can't and don't. But all the gray area isn't good for anyone.
Of course, with that said, I have no idea how exactly to fix it. Any suggestions?
