Semi-bluffing in poker is when you bluff with a hand that has the potential to improve on the next card, but even if it doesn't, you still have a chance of winning the pot with a bluff.
A semi-bluff is different from a pure bluff because in a semi-bluff you have some equity in the hand, meaning you have a chance of making a winning hand even if your opponents don't fold. This is particularly useful when you have a drawing hand like an open-ended straight draw or a flush draw.
