Hi all;

here another problem from a tour I newly directed:

Scoring: MP

West North East South
...-... pass. pass 1♦
pass. 2♣... pass 3NT
pass. pass. pass

West leads J of spades and declarer takes the first 8 tricks:
1♠ 5♣ and A, K of ♦
then he leads 6 of ♥, West contributes the 9
and time run out.


This was the 5 card ending; Heart 6 and 9 played to zhe 9. trick.

Scoring: MP

West North East South
...-... pass. pass 1♦
pass. 2♣... pass 3NT
pass. pass. pass

West leads J of spades and declarer takes the first 8 tricks:
1♠ 5♣ and A, K of ♦
then he leads 6 of ♥, West contributes the 9
and time run out.


It was a machtpoints tournament with 6 min per board.
I was never called to the table. I had to assume, that all players were responsible for the delay. I found server scored A--:
I didn't adjust so A-- was scored.

Later I looked at the traveller: The only possible results were 3NT+3 or 3NT= depending on South finessing Q of ♥ or not.

On the traveller 3NT got 22% and 3NT+3 64% for NT. In this respect 40% to N/S seems fair, if you assume declarers choice of line; to impass or not to impass; beeing 50% for each.

But what about EAST/WEST? If declarer finesses they would have got 36% and if he does not 78%. Therefore they deserve actually (36%+78%)/2 = 57%.

IMO the fair score shoold be NS=40% and EW=60%. But this was only possible to find out after looking the traveller in MyHands.

I'm looking forward to hear your opinions.

Cheers

Al
