Play tight at the beginning and watch the play when you are not in the hand.
As the tournament progresses, maniacs will be eliminated and their chips consolidated into more capable
hands. Hopefully you were able to get some. People will get more in line.
When people talk of bluffing, it seems most are talking about some crazy bet-with-nothing bluff that works on the river for all the chips...
Bluffs come in all sizes. Stealing blinds, continuation bluff, floating.
All types of bluffs that work in their own time and situation.
Figure out when the time is right and who is concerned enough to fold.
