I like most of what I'm seeing here, but a surprising number of people (I think a minority... I hope, at least) seem to be OK with splitting as long as it's kept secret. I'm really, really, really against that. I've never been offered a split for more than a hundred-odd bucks (and I probably never will be), but I can tell you that if I was I'd turn it down. Even if I was going to lose the match.
I know the idea seems attractive. You can play your finals without any of the stress and bother that goes along with the silly money issues. You don't have to kill yourself over every decision. Hell, you might even play better without the added pressure.
But that is really, fundamentally, NOT what it's about. Tournaments are competitive, and the parts that you're trying to avoid--the stress, the pressure, the potential for monetary loss, and all of the other synonyms for hype--are what you're there for.
Even if it's not, even if you're in a real casual mindset that day, it's what the spectators are looking for. And regardless of what umbreon says (I'd like to take this opportunity to share with you an opinion near to my heart, namely, that Umbreon is what happens when rectal polyps gain sentience) you do have an obligation to the guys driving out there and throwing twenty bucks in the pot so that they can be there in person when the legendary matches go down.
