The Tao of Gaming

Boardgames and lesser pursuits

Another Bridge Note

Apparently someone just proved that the current algorithm used to deal ACBL tournament hands are insecure. If you enter in the exact card for three boards in a row, a program can correctly predict the rest of the hands (for the 36 deals) because it can compute the supposedly random seed for each hand.

Crypto is hard. The ACBL is already migrating towards a better hand generator.
