about me

Semi-retired mathematician (numerical analysis, applied math, linear algebra, statistics, etc.) I like woodworking, especially wood turning. I enjoy writing up bridge hands, which I find can improve my own play, by forcing me to think about what is happening at the table.

Would you roll this back?
North played the contract, not South. Along the way, North took a diamond finesse to the queen. Seeing the jack told him to then hook the 10. At least that is what I think happened. There was some confusion due to the director call.

Would you roll this back?
What was the pointless question? We try very hard not to ask questions at all until after the bidding, unless there is a need to do so. In this case, since South has doubled partner's bid, it might be pertinent to know if double was penalty or takeout, or ...
Would you roll this back?
South did not know X was specifically 5-7. South said privately afterwards that since he did not know how to show the hand directly in their system. So he decided to start with a double. It was then alerted, and immediately described as 5-7.
Would you roll this back?
The X was alerted, and immediately explained as 5-7.
percentage play in trump for 1 loser
"There is no holding where the first finesse loses where a 2nd finesse will avoid the loss of a 2nd trick." RHO must cover on the second round. Now you see the split, and can stop drawing trumps, to play for a trump coup position in the end game.
