I think it's a giant conspiracy between you and whoever is making these contests. You cut a deal ahead of time to make the rest of us guessers look like total morons.
That's just silly MG. What I'm actually doing is stalking all BTPers so I can see these hands go down. Sure, it takes a lot of time, but it's already paid off $10!
I mini-raised because I wanted to build the pot. I thought he had a made flush, and I didn't think he would fold it. Too many scare cards on river if he has a non-nut-flush. And if he had a draw he should pay to see the river.
