I think you can use bluffing and of course, you need to confident in pretending that you have a good card so another player will think that you have good cards. but this cannot works if the other player has a really good card so you will lose the game.
It has to work if you were good at bluffing because that's the point of doing it, being able to make those who have good cards fold because you are betting too much that they think that you have a sure-win pair of cards. You have to scare them down that they end up folding. Even with good cards, they question themselves and go like "This guy probably has really good set of cards." This works especially when there's an obvious possible flash or straight in the combination right when the 3 cards are put down. For example, there are 3 cards of the same sign or the 3 cards' numbers are near each other.
but playing with good cards will be recommended as you don't have to worry about anything because you know that you can win. but it is difficult to always get good cards in poker since we can get a random card.
But is betting high with good cards can still be considered as bluffing? Bluffing, according to
Urban Dictionary, means "saying you have something that you don't ..." And you basically 'speak' and pretend that you have good cards by betting high or even going all in just to scare them off. Bluffing, when you have good cards, would mean that you're not raising high, you're just going with the flow. You're just going to be checking/calling with the bets faking that you only have relatively good cards and that you just wanna see it through the end.
