Think you're good at poker? Computer scientists say they've created an algorithm that pretty much can't be beat and that it's guaranteed to beat every single human competitor. You can challenge it here, but be prepared to lose.

Dubbed Cepheus, the poker-playing program essentially solved Texas hold'em. It can learn from past mistakes and achieved a high status by playing billions of hands against itself. It can even bluff. Thank goodness none of your friends know the secrets to this algorithm.

So go ahead, try and challenge Cepheus here.
