An important and vital weapon in the no-limit Texas holdem games is the semi-bluff. The most popular time to semi-bluff is when a player has a flush draw.

When used correctly, the semi-bluff with a flush draw can be a very effective tool. When overused, it can be costly. This is the subject of many poker strategy articles, including this one.

What is a Semi-Bluff with a Flush Draw?

A semi-bluff is a bet you make before you have a made hand. If your opponent folds, this is a great outcome, since he almost certainly had the best hand. If he calls, you still have outs to make the best hand.

In on of your Texas holdem games, if you hold two hearts and the flop has two hearts, an all-in bet would be a semi-bluff. If you are called, you will probably win if either of the next two cards are hearts. If your opponent folds, you win the pot without having to make a hand.

When Should You Semi-Bluff with a Flush Draw?

You should semi-bluff with a flush draw when the pot is sufficiently large that it is worth winning immediately and when there is a reasonable chance that your opponent may fold. A nice play is the semi-bluff check-raise.

For example, you check an opponent bets $25 and you call with Qd Td. The flop comes Kd 8d 6h. You check again, your opponent leads out for $100 and you check-raise for $200 more. If your opponent does not have at least a pair of kings, he pretty much has to fold (unless he holds the ace high flush draw, but this is unlikely).

Even if he has a hand like AK, your check-raise has indicated a powerful hand, perhaps K 8 for two pair or a set of 8s. Therefore, he may fold the winning hand immediately. If he calls, you will still win with a diamond on the turn or river.

When Should You Not Semi-Bluff with a Flush Draw?

If there is no chance your opponent will fold, such as may be the case in free online poker, you should not semi-bluff. Also, if your flush is not likely to become the best hand, for example the board is paired or your flush draw is very small, you should usually resist the temptation to try a semi-bluff.
