My two cents here is that you have only two extreme tactics in a freeroll...don't play anything but AA or KK for the first two hours, or play anything resembling a decent hand based on your table position. I can tell you that I've tried both avenues with an equal lack of success, but if I had to choose one, it would be the latter. Simply for time value. Play tight and waste three hours waiting for the inevitable suckout bad beat. Play aggressively and either build up a strong starting stack or bust out early. When you look at the payouts of an average no-add freeroll, it's just not worth four or more hours of hard grinding to finish in the money with chump change. For that reason, I'm starting to come around from my previous hard stand for tight play to a looser "make or break quick" approach. Which is not to say I play rags and pray. But I'll play more middle pairs, unpaired paints, and suited connectors. There's no getting around the fact that freerolls are 90% dumb luck lottos which are much more about how stupid bad the other guy is than how good you are. All you can do is grab as many checks as possible to give yourself the best chance of winning.
