The point of the bluff and win award is that you will have to force a player out of the hand that is holding the best hand.
Example:
Let's take the 7 2 offsuit you call before the flop. You should probably fold but you called.
Now on the flop it comes A of hearts 6 of spades and 8 of spades.
What you don't know is that your opponent is holding AK of diamonds.
You bet out... the opponent calls thinking he has the best hand. Now a a 10 of spades comes of.
You still have nothing but you bet even more. The opponent calls again.
On the river the J of spades comes of. You still have nothing but now you go all in.
The opponent folds.
You show cards and get the reward allin on a bluff and win award.
Hope this helps
