Yeah, like monster said, you don't have to know all of 'em. Just memorize those ones, and r3,r2,r1 (ready to recapture the flag) and c (carrot) =/= nc (no carrot), and the PU camping and taking ones.
IMO CTF is less competitive and more''for fun'. There are only 4 active clans, and there are no new games from the previous week, so that's hardly a competitive atmosphere.

The official SP levels are made for the lowest resolution in the game AFAIK.
