Odds and Expectation

Martin Tompa

Unfortunately, luck was not with you in that last deal against Katharina in tonight’s tournament. Though you found the play with the best expected gain, the wrong card was face-down in the stock. As a result, Katharina is now only 1 game point from winning this match. The pressure is on.

Unseen cards:

J
♣ ATK
TQ

Your cards:
A
T
♣ Q
AK

Trump: J
Stock: 1 face-down card
Game points: Katharina 1, You 4
Trick points: Katharina 38, You 41
On lead: You

Your hand looks promising, but trump control seems balanced on a knife edge. Plan your play. When you think you have come up with a good plan, you are welcome to read my analysis.
