Toss top and bottom board

[hotShot]

Let us assume a board where the declaring side playing 4M (nonvul) is missing 3 aces and there is no way they can avoid to lose these 3 tricks.

At one table the contract is doubled making.

 

Score method 1:

Both sides at tables where 4M= was played receive 0 IMPs.

The pair declaring 4MX= wins 5 IMPs over 4M=.

The pair losing 4MX= loses 5 IMPs againt 4M=.

 

No result is lost.

 

Score method 2:

Assuming that the board was played n-times.

Every declarer making 4M= gets -5/(n-1) IMPs.

Every defender gets +5/(n-1) IMPs.

The pair declaring 4MX= wins 5 IMPs over 4M=.

The pair losing 4MX= loses 5 IMPs againt 4M=.

 

 

The question is, do we want that the pairs playing 4M=, where both declarer and defender made only right choices, separate in their score by 2*5/(n-1) IMPs?

 

Obviously for large n, the methods produce equal results.

 

Playing in the MBC the "Highscore" could be 7MXX-3 producing a even larger distortion.

And why should defenders be punished because we are the only ones in the room to have a blackwood error and bid grand off a finessible trump king? Because that's the way it works. Swings and roundabouts.

Heh - serendipity strikes (otherwise known as Mycroft should watch what he says).

 

1) Both partners invert DEPO, but one remembers in time to pull 6Cx to 6H. Makes on two of two finessable kings.

2) 1NT-2H; 2S-4H; 4NT-5S; 6S. Partner forgot 3H was forcing, so 4H is splinter, so we're keycarding spades, not hearts. Makes when SAQx is onside.

 

Embarassed? Sure. Gonna give back the matchpoints? No way.
