More Extremes of Luck

In today’s column I will continue my tales of probability extremes and woe against Doktor Schnaps. I was at the end of a tight game. We’re down to the last deal with the game point score 1:1. I’m on lead having been dealt the ace of trumps and ATKQ in an outside suit. What to do? If Doktor Schnaps has 0 or 1 trump, I can close the stock and win the game by cashing the trump, declaring the marriage, and running the rest of that suit. If Doktor Schnaps has 2 or 3 trumps, I’ll lose the game by closing. I don’t fancy my chances much with the stock open; it’s never a good starting hand to have four cards in a nontrump suit, because the opponent will gain the lead and keep playing cards from the remaining suits. I wish I knew what the probability was that Doktor Schnaps has 0 or 1 trump. I get out a piece of paper and start to work it out, but I’m concerned that I won’t be able to compute the probability quickly enough before my game times out. My hunch is that my probability of winning is pretty good. With 5 cards in its hand, 9 face-down cards in the stock, and 3 trumps I can’t see, the expectation is certainly for Doktor Schnaps…
