i will only bait in one circumstance. online if i have a dead stack to my left and i'm SB and it folds to me...i'll sometimes tank and call, then tank and check, tank check, tank check and see the showdown for the 2bb against the dead stack so everyone thinks i'm an idiot. that only works at a point in the tournament when you're fresh to a new table but there's plenty of chips around to play with. also works if you have a huge stack because they will assume you got them all on a stupid all in that got lucky.
maybe people don't pay attention to that, but if i ever see someone lose to a dead stack i try to pick on them later.
