[Jeff W]

I have a wager with my friend on a point of game theory. Can someone verify my claim below? If you have a link to a credible source, I would appreciate it.

JeffW Okay, my wager is
JeffW In a two person zero sum game
JeffW The player who is second to act
JeffW Always wins or ties under the following conditions:
JeffW 1. He has perfect information about the game.
JeffW 2. He plays perfectly under all contingencies.
JeffW okay, 2 six packs of beer valued at no more than $15 total.
