1) Same way as for every other match. If I called it differently, my head would be called for on CD, if nowhere else, for inconsistency. (Also note that this is also a scorekeeper call--same response.)

2) Quite possibly. However, I'd probably be more focused on the win.

3) They are strategists and tacticians. They may have also found a way to capitalize on the seeding score system.

If I did seed first, I would promptly proceed to ask the lower-ranked of OneABot and TwoABot to ally with me. My real goal, of course, would be the higher-ranked one, but the lower-ranked one would be an acceptable partner. Should they decline, then I force the higher-ranked one's hand by asking them to an alliance. Mission accomplished either way.
