Board-a-Match

[gnasher]

I think to summarize what Justin said, the point is that it's unnatural (in that someone decided some scoring difference should simply not matter) and arbitrary (in that someone decided 10 points doesn't matter but 20 points does).

True, but that's also true of the IMP scale, which we all seem quite happy with (well actually I'm not, but that's for another thread).

There are two major events in England that use hybrid scoring:

 

The Lederer (an invitation teams event) uses scoring like that described by Patapon, but with 12-board matches in a round robin movement. The BAM element makes up 2/5 of the available VPs. 10-point swings don't affect the BAM element. I think you should bid like at IMPs but play like at matchpoints.

 

The Pachabo is an inter-county event, with three-board matches again in a round robin. The scoring system is arcane. You get 6 points (2 per board) for the BAM element (again, a 10-point difference is a tie), and up to four more from the following method:

 

Firstly, the total aggregate points scored (regardless of whether plus or minus) at the two tables put together are calculated. Secondly, the total aggregate swing in the match is calculated. Finally, the total aggregate points are divided by the swing, and the result converted to Victory Points as per the schedule described below. Two examples of this process are described within.

 

If total points divided by swing are:

  greater than or equal to 12:  2  -  2    VP s

  less than 12, but greater than or equal to 8:  2½  -  1½    VP s

  less than 8, but greater than or equal to 5:  3  -  1    VP s

  less than 5, but greater than or equal to 3:  3½  -  ½    VP s

  less than 3:    4  -  0    VP s  12:  2  -  2    VP s

Thus the right strategy on a particular board depends upon what happens on the other boards in the same match.

When we play 4 boards match, then 16 points are available in each match.

-8 for the BAM points- 2 on each board as you win 2-0 or tie 1-1

-8  of these points came by converting IMPs to VP scale(8-0,7-1,6-2,5-3 or 4-4)

In England, the Lederer Memorial trophy is played in a similar way.

 

Twelve boards per round, with 60 points available in each match.

- 36 points come off IMPs being converted to VP scale

- 24 points on a "BAM style" -- 2 for a win, 1 for a tie and zero for a loss.

However, at Lederer, a 10 point difference counts as a tie.

In essence, the "BAM style" is 2 for winning IMPs on a board, 1 for a push board and zero for losing IMPs on a board

In the Norwegian version of Patton we play 7-board matches.

14 points in the match are divided by BAM scoring (2-0/1-1) and 6 points are divided by a method similar to the EBU regulation quoted by gnasher above (6-0/5-1/4-2/3-3).

Alain will you be in Pula this year? I will!

I still don't know but maybe !

 

Of course I will be very happy to meet you if I go ! :rolleyes: :)

We do? I'm simply not inclined to change but I think it could definitely be improved.
