@tuban_muzuru @rysiek @futurebird I'm not trying to annoy you! Just pointing out that probability calculations don't work if you're missing crucial info: in this case, that the dealer is crooked. He's only shuffling 49 cards - retaining three of the aces to bottom deal as needed. 🤷♂️

But even math is tricky! Assuming a *fair* riffle shuffle and any number of *fair* cuts, what's the probability of dealing four cards, one of each suit, first attempt?

Always 1, if the Gilbreath Principle was used.
