You Need Chips to Bluff

If you're going to bluff someone off a pot, you need to have enough chips to push your opponent off her hand. Otherwise, your raise or bet won't be enough to scare them. Here, one player waits too long and doesn't have enough chips to bluff her opponent. Her minimum raise on the river isn't enough to scare her opponent who doesn't even have a pair. She probably should have raised him on the turn or made a larger raise on the river for the bluff to work.
