Planning and executing a multi-street bluff effectively requires a deep understanding of your opponent's playing style, tendencies, and table image. You must carefully select the right situation, taking into account factors such as the board texture, your opponent's range, and the pot odds. A well-executed multi-street bluff involves creating a believable narrative through your betting pattern, using a combination of bets, checks, and delays to build credibility and uncertainty. Timing, table talk, and body language also play crucial roles in selling the bluff and making it more convincing.
