Defense, It's still here.

They won't be able to score substantial herding or hurdling points for 6 quads of movement.

*This is legal so long as your robot itself does not cross the lane divider between your home stretch and their post-home-stretch. IIRC, you can still move clockwise within a quad, just not clockwise from quad to quad.

Those are my thoughts exactly.
Now, question is, maybe it is worth for you to just stay in their home strech zone the whole game and dont let them score. That is deffinately defence.
