Hold the deck in one hand with the long edges supported by your fingers and thumb
Split the deck into two equal halves
Place the inner corners of the two halves together
Bend both halves slightly upward with your thumbs and fingers
Apply even pressure so the cards interlace as you release them
Let the cards fall together smoothly into one stack
Square the deck by tapping the edges against a flat surface
Repeat the bridge only if needed after a shuffle
