3 by 3 chessboard

first, i said "in life", refering to the people i live and work with, not the internet. i know there are thousands of people who love math.

seccondly, it is a game tree. it accounts for every possible outcome of a game. EVERY SINGLE POSSIBLE WAY. yes, three spaces to start out with. but consider this: there are three moves white can start out with. then, following the move where the middle pawn comes out, there are 4 moves black can make. then, following one black pawn taking the middle pawn (but remember: you have to account for both), then there are 4 moves white can make. already, we're talking about 20 outcomes in the first 3 moves. in total, there are roughly 150 outcomes.
