Bluffing is
a poker strategy where the player pretends he has a strong hand, when
it's actually the opposite, in hope that the other players will fall
for this trick and call his bluff.
It is called semi-bluffing when you actually have a winnable hand,
but not right now. However, you have the chance to outdraw the other
hands. If everyone folds, you win the pot outright, if they call you
still have a chance because the next card may be your winning card.
Bluffing is exciting but you must use it wisely. Before bluffing,
you must have a reason to suspect that your opponents have weak hands.
It is also important that you have a good record. If you are winning
many pots, the other players are more likely to believe your bluff
and eventually fold.
