Some players essentially never bluff. When they bet all three streets, unless you have an incredibly premium made hand, you should fold. You simply must learn to fold your normally-strong bluff catchers against people who never bluff if you want to succeed at poker.
This concept was demonstrated in a hand played by one of my students in a $1/$3 no-limit hold’em cash game. In a seven-handed game with everyone sitting on an effective stack of $300, the player in the hijack opened for $10. In earlier action, this player had a pretty obvious spot to bluff but did not pull the trigger.
