With Or Without You vs. Magnitude
For this fight I shan't bother with lowering the front horn, I'll merely keep it ground scraping and use it to lift either one of the clusterbots up should I encounter one of them. I'll try and drive defensively but be offensive when I have the chance, focusing on keeping my wedge pointed towards With You as I believe that poses more threat of getting under me, and when I go on the offensive I shall go for whoever is nearest and generally flip either cluster when/if I get wedged under it. If I can't get Without You flipped over I'll try and get With you out of the arena or into the house robots!

Shovearound 2.5 vs. Gabriel IV
I think my nose should be able to get under the forks due to their shape, I think if I ram into it my nose is far more likely to go between the forks than up one of them and from there I can wedge further underneath and flip. Nonetheless I'll try and aim away from the forks, and use the nose to get under the skirts and get well under it and flip. If flipping starts to prove impractical I shall go into thwackbot mode and try to warp the skirts with the spikes so I can get underneath them easier. As with WOWY, get it flipped out of the arena as soon as is practical, or into the house robots.

Ge5orce (4) vs. N³
Usual tactics here - go for the sides of the main wedge and get underneath there, using the forks to hold it if necessary, and then immediately bring the crusher down with full power - 8 tonnes of force on the crusher should outweigh 1.6 tonnes on his flipper and prevent him from escaping like that, and from there I can hopefully keep those wheels off the ground and carry the lovely Ge5orce over the threshold of the pit to spend a happy marital life doing...something or other. Probably spending the rest of their operational lifespan raising a new brood of hydrostatically powered flippers?

Best of luck everyone
