When the player doesn't keep track of Azzie politics, but the character has points in it, you don't just say 'Yeah, you know why this corp is doing this. They're with the Azzies, and it has to do with the Az-Am war, and-' No, you don't just throw the data at them when it's convenient. They wake up in the morning, and you throw them a small list of news updates - "Aztechnology denies claims of violence against protesters." lining with a small bulletin from a pal, "I'm catching word about a new H&K model. Number only, my guess is an Assault Rifle. Keep your eyes out, if you get any R&D jobs, ya hear?"
Tell your players things that you've established they should know. Remind them that Lowfyr is internationally one of the most terrifying beings conceivable, when they consider taking a job in his backyard that might piss him off, because we don't live in a world where dragons can, and do, eat people. It's easier to forget that sort of thing.
When they make stupid decisions, and they're informed, let them screw up. LET them try shooting Hans Brackenhaus, after their contacts have told them about what that handle means. Sure, let them get shot up in a KE ambush for knowingly not hiding their datatrail, after blanking some KE databases of their crimes. But make sure that they had the opportunity to use their head, and say 'I should avoid this. x data that I've been subtly given, says so. I mean, this one contact said no, but the rest agreed, so...'
Never give them the full story. Force them to pry the truth out of the dead jaws of whatever Johnson was about to screw them that week. Make them work for their understanding, and if they don't pursue it, let the matter die. If they ask, out of character, what happened, tell them they don't know, and they never will, because they didn't hunt down leads while they had time.
Give players consequences, harsh ones. Drive them crazy wondering, have the Mage go in for a vat-grown replacement arm after a bad fight, but don't try to wipe them off the face of the earth for nothing. Give them the tools to succeed, in the form of information.
And always insist that every member at your table have a second sheet drawn up by the third session.
