1) Identifying donkeys and calling stations, going card dead, and then trying to bluff the idiots with nothing when i get pissed at thier stack being 2x mine.

2) The "Dark tunnel bluff". Before bluffing lately i have been asking myself, "Is there anything on this board he could possibly be scared of to push him off his range?" More often than not the answer comes back 0...thus resulting in WAY less bluffs (i think my tourny results kind of mirror this in November).

3) Recognizing the players at my table that are WAY better than me and still playing hands out of position with them.

Tons more, but those are me biggest.
