Q: What is Serpentin ranking? I found it in the Contest menu > Settings > Scoring tab.
A: This is a method used by the French Bridge Federation (FFB) to create one overall ranking in spite of using two-winner movements.
The traditional way when using Mitchell without arrow switches is to have one ranking for North-South and one for East-West. The FFB sometimes prefers to have one overall ranking. To overcome the fact that North-South results have not been compared to East-West results, the ranking is created in the following way:
- The highest overall score is the winner. Let us assume this is an East-West pair.
- Second place now automatically goes to the highest North-South score, no matter if this is higher than the second East-West score or not.
- Third place goes to the highest remaining score, no matter the directions of the first two pairs. Let us assume this is a North-South pair.
- Fourth place now automatically goes to the highest remaining East-West score, no matter if this is higher than the third highest North-South score or not.
- And so on, until the selected number of pairs have been reached.
- Below that, no matter the direction, the ranking is set according to the score.
The FFB recommends 3 pairs from each line when below 70 pairs, 4 pairs when below 100 pairs, and (number of pairs) / 20 above that.
