Jim and Tom play a game.

A dodecagon (i.e., a 12-sided polygon) is drawn on a piece of paper. They take turns drawing diagonals, i.e., a line segment to connect two non-adjacent vertices. However, they are not allowed to draw a diagonal that intersects another diagonal already drawn.

If a player can't draw another diagonal, he loses and his opponent wins. Jim draws first and Tom draws second. What's the correct strategy for Jim to win?
