"So how do you play this game?"

"Easy. We just take turns putting pieces down. You have to place yours so that some number of mine in a line are surrounded on either end, then the surrounded ones flip and they're yours."

"Who wins?"

"Whoever has the most when we run out of moves."

"Okay..."

"You're black. You go first."

"So then I flip this one... right?"

"Yup."

F5......G6
G5......G4

"Errr... ummm..."

"Try thinking about what moves you leave open for me, and what those will leave for you. It's not just about how many pieces you flip each turn. It's only mostly about that."

"This is cool. A piece could be flipped a whole lot of times in a game."

"You have a keen grasp of the obvious."

"I wonder how many times this one over here will get flipped in a game..."

"So keep count. But for now, play."

"Crap. Pass me another beer."

"We're all out of Rolling Rock."

"Any Coors?"

"Errrrr... 1 2 3... 24 25... 40... 50 51... and I have 11... so if I did this, then you did this... no, that doesn't work... that doesn't work either... okay, you win. Let's watch Seinfeld."
