An important concept that David Sklansky was the first to treat. This is bet or raise, hoping not to be followed, while having few outs if this were to happen. A semi-bluff may be appropriate if a real bluff or value bet is not, since the alliance of the two can help you get your game well. Example: you have KQ and the flop give T-5-J. If you bet now, it’s a semi-bluff. You have probably not the best hand and you would like your opponents pass right away. However, if you follow, you can always improve your hand.
