The map has 8 towns (T1 to T8) and 9 roads (A1 to A9). Take it in turns to claim a road, blocking it completely to your opponent (N.B. your road may go through 3 or even 4 towns and when you claim it you block it completely from end to end).

To win you must block all the roads from one of the towns (i.e. 3 different colours).

Can you devise a strategy so that you never lose?

Can you explain your strategy?
