Avoid the Ducking Ruff

Martin Tompa

“All right, Hans, all right,” says Uncle Claudius. “We get it now. The way I played that last hand, I should have lost to your ‘ducking ruff’ play. Well, then, how should I have played the hand?”

“I’m glad you asked,” replies your clever Uncle Hans. “Let’s set up the hands again, but this time from your point of view, Claudius.” Hans rearranges the cards on the table to recreate the situation at the beginning of trick 5.

Unseen cards:
KJ
AKQ
♣ —
A

Claudius’s cards:
AQ
T
♣ —
TQ

Trump: T
Stock: 1 face-down card
Game points: Claudius 4, You 6
Trick points: Claudius 38, You 0
On lead: Claudius

Uncle Hans goes on. “Claudius, you led Q here, and we saw that that ends badly for you if it gets trumped. Does either of you see a better play for Claudius?”

Do you? When you have come up with a good plan for Claudius, you are welcome to read my analysis.

I am a Professor of Computer Science & Engineering at the University of Washington, where I teach discrete mathematics, logic, probability, design and analysis of algorithms, and other related courses. I have always loved playing games. Games are great tools for learning to think logically but, more important, seem to me an integral part of happy family or social life. I will be delighted if game-players, parents, teachers, and students find this series fun and useful.

My excitement about Schnapsen was rekindled by playing against an iPhone program called Master Schnapsen/66 written by two friends at Psellos. Set to play at its “Master” level of difficulty, this program is one of the two most formidable opponents I have found. It comes up with surprising and brilliant plays, and I have learned an enormous amount of Schnapsen strategy by playing with it. Nearly every deal in this Schnapsen Log arose during those hours of playing with Master Schnapsen/66.
