There is a lot of luck late in the tournament, which is where my game falters. not because i don't do it okay (okay, not great), but because I just don't have luck.
If you wait for premium hands you will blind out unless you are already very big or very very lucky.
i like raising aces, even weak ones. remember if you have one then that's one less in the deck for them to have (obviously don't chip off with A2 or other crappy ones unless you or they are really short) and Ax is a large part of the calling range so the steal will work more often.
obviously table dynamics matter. Also look for the guy who is on a heater and catching everything (you will likely notice him from his big stack and very loose play). Don't steal if he's in the hand unless you think you have a profitable flip or better.
