my solution

1. Whenever he puts an "O", I put an "O" next to it if I cannot find a win

2. Whenevr he puts a "S", I put a "S" with two empty spaces in between if I cannot find a win.

3. If he never put a "S" first, Then I watch for the last 7 consecutive empty spaces. Then I put a "S" on the 4th slot so that I can put a second "S" with two empty spaces in between.

4. If he uses the same strategy to me, I still can win because there are 2010 spaces.
