end-game strategy with callers

[cbloom]

I'm curious about general play in the endgame when people are calling too much. That is, something like 4-5 handed, when the blinds are very big (average stack has an M of 8, say). I've read plenty and play fine when Harrington style or Sklansky-gap works, eg. when callers are rightly folding to not risk their tournament life on close races, but if callers are willing to call allin with hands like A2 and K8, you can't play open-aggressive so much. On the other hand if you try to wait for big hands to trap, you'll be blinded off, and if you just wait for hands like AT, you may well be racing anyway, and with fewer chips since you waited.
