What are your preferred strategies as unrevealed cylons in the various roles, both offices and characters? In many cases, going "uh... yeah... haven't got enogh cards to do anything helpful right now..." may be good enough, but what tactics are there that are both somewhat effective and still leave doubt about your loyalty?
Everyone can slip a (preferably common) bad card into a skill check.
The admiral can obviously pick bad jump targets, especially if the target hasn't been scouted yet.
The president can sit on a pile of good Quorum cards, though he likely won't survive being voted out of office when his successor takes a look at them.
Tactics characters can bury good targets when scouting.
So... what else? How do you find your partner? And how do you deflect suspicions right onto another human?
