Semi-Bluffing

Semi-bluffing is the name for bluffing when you also hold a drawing hand.

You currently only have ace high, but you may hit a spade flush or make a pair of aces or kings.

If you bet with this hand, you are bluffing, but you also have a high likelihood of gaining a strong hand on later betting rounds.

Semi-bluffing can be a very useful technique, especially in no-limit games.

Pure Bluffs

These don't work too well at limit, but they do work at times. At higher levels, if the flop is kinda scary, say AQ9, if the action is passed to you and there aren't many in it, go ahead and bet at it if you had shown strength preflop.
