It would be very well known to any regular poker player that with the right cards, in Texas Hold 'Em a flush draw betting would prove to be very very profitable.
Here we explain, how exactly and in what particular situations should one bet a flash draw in order to win maximally.

• One should bet or raise the flush draw only if the following situations arise--
• When against weak or timid players who have a tendency to fold.
  
• When against those foolish players keep calling whether they have enough cards or not.
  
• When after your flush draw you are in possession of a straight draw as back up.
  
• When without being in possession of a pair/straight draw it may be done if the flush draw is over nine.
  
• One should NEVER bet if the following situations arise-
• When against very strong players who won't stop from raising any bet.
  
• When you are not in possession of a straight draw as back up done or if the flush draw is not over nine.
  
• It is necessary that the player calls for a large bet to get a flush draw.
  Your aim should be to convince your opponent that you are in possession of an excellent or a mediocre hand as the case may be, so do play in that fashion.
  Say, for example, if four cards are flop, and the player gets back in action the bet should be 4-7x.
  This would mean that you are in possession of a good hand but you are tensed that someone may catch a flush.
  This would be defined as a good bet as if you are playing with strong players you would be easily be able to pick up on the bet.
  The usual mistake on the part of your opponents would be trying to bet bigger after your flush as they would misunderstand this as your possibility to fold.
  
• On flopping four cards to the flush, if you still have a straight draw or even a pair as backup, you may play aggressively.
  If someone in the table bets 1-4x, the size of the pot may be increased, this is because of the presence of such many outs.
  The above guidelines should be followed only when NOT to raise or bet the flush draw.
  

Once a flush is hit, be sure to act first and by this you will get everyone to surrender.
