You and I will play a game. I lay out N coins of different denominations (i.e. nickels, dimes, quarters, pennies) in a straight line across the table. We each take turns choosing one coin from either side of the line - meaning, you can only choose one of the end coins. We keep picking coins until none are left. The winner is the person whose sum of coins is the greatest. I let you decide if you go first or second. Do you wish to go first or second? And what is your strategy?
