Tango and Cash are playing the following game: Each of them chooses a number between 1 and 9 without replacement. The first one to get 3 numbers which sum to 15 wins. Does any of them have a winning strategy?
Place the numbers from 1 to 9 in a 3×3 grid so that they form a magic square. Now the game comes down to a standard TIC-TAC-TOE and it is well-known that it always leads to a draw using optimal strategies by both players.
