Let's go, I'll try to explain it to you. You can bluff before the flop, after the flop, on the turn, and on the river.
Bluffing in all betting windows is crazy. Evaluate your range and your opponent's range to create a specific bluff line that makes sense to be a bluff according to the board.
The worst time to bluff is near the bubble or on the exact bubble and at the beginning of the tournament. Other than that, evaluate the conditions to bluff with some
equity for value in case the card you need comes.
