Our team employed a version of this strategy in a qualification match at PNW District Championships. Our intent was to remove all the boulders from the neutral zone into our opponents courtyard. We wanted to have a partner sit at the end of the opponents secret passage to prevent reintroduction of boulders, but that did not work out. We also had our human player try to not roll the boulders into the neutral zone.
We chose this strategy because we were considerably outgunned by our opponent and they had a robot that shot high goals from the outerworks. We also wanted to see how effective it could be. Our robot can cycle pretty fast.
We had some success with this strategy. I think this will be a rare strategy since it requires considerable commitment by each alliance partner. Probably only in eliminations. Trying to convince alliance partners of this strategy is a tall order. Many times we couldn't convince partners of the need for defense and hence there was a 48% capture rate in quals at this event.
I also agree with the suggestion that you should not score the boulders for the first portion of teleop.
Watch the video. I would appreciate any suggestions on how to make this strategy more effective. I expect we will see this strategy at champs elimination rounds.
