2014 President’s Awards

by Matthew Kidd

At the January 11, 2015 unit game, president Matthew Kidd presented the second annual President’s Awards. These awards are based on the unit game results for 2014 and emphasize partnership performance rather than individual performance.

The full set of awards given are listed below:

Best Game 70.53% Andy and Patricia Loh
Best Partnership 56.40% average Kent Hartman and Maritha Pottenger
Best Slam Partnership 0.90 slams / session George and Kathee Bessinger
Most Improved Partnership +5.37% average Freda Anderson and Gail Dunham
Most Consistent Partnership σ = 4.03% Barbara Norman and Chuck Wilson
Wildest Partnership σ = 7.71% Andy and Patrica Loh
Best Attendance 23 of 24 games Freda Anderson, Sally Ishihara, and Sue Kane
Best David Partnership +4.24% Sam and Yoko Jordan
Best Bottom Feeding Partnership +2.47% Elaine Chan and Mike Mezin
Best Pair-Pair Overperformance +18.92% Kent Hartman and Maritha Pottenger
against Kathleen Hennessy and Tom Tatham
Best Pair-Pair Overperformance +18.83% Morton and Eileen Heinrich
against Kent Hartman and Maritha Pottenger

Best Game is straightforward. Bill Grant and Lynne O’Neill held the lead for half the year with a 70.04% game in February though Everett Boyer and Greg House took a shot at them with a 69.68% in May. But Andy and Patricia’s 70.53% game in September was untouchable.

For 2013, best partnership was clear. Ron and Mary Huffaker had a commanding 57.80% average based on 22 sessions. 2014 is very ambiguous. Kent Hartman and Maritha Pottenger have a 56.40% average based on 14 sessions. But Mac Busby and Steve Johnson beat them with 57.93% though only based on 8 sessions. Steve and Kitty Cooper do even better with a 58.55% but only based on 5 sessions. Lynne Feldman and Judy Rimer beat this with 59.29% but based only 4 sessions. The Coopers have a large standard deviation of 7.17% such that their 5 game average works out to 58.55 ± 3.18%, a high degree of uncertainty on the mean and their 4 game average in 2013 was only 54.89%. But Mac and Steve’s result is tighter at 57.93 ± 1.93%.

George and Kathee Bessinger won the Best Slam Partnership for the highest average number of slams bids and made per session. See Slam Statistics for more about this. Close behind were the partnerships of Elaine Chan and Mike Mezin and Sam and Yoko Jordan, both averaging 0.81 slams per session.

The Most Improved Partnership compares 2014 performance against 2013 performance. Freda Anderson and Gail Dunham zoomed up 5.37%. Wow! This is huge for a partnership average over 17 sessions in 2013 and 18 session in 2014. By comparison, Barbara Norman and Chuck Wilson won this category last year with “only” a 2.71% improvement. Also improved were Mac Busby and Steve Johnson, up 2.55% in 2014.

Barbara Norman and Chuck Wilson won the Most Consistent Partnership. Their low standard deviation of just 4.03% is close to the theoretical minimum observed in Partnership Variability. George and Kathee Bessinger were even lower 3.77% but this based on only 10 sessions rather than the robust 22 attended by Barbara and Chuck. Larry Sherman and Ying Lin Gu also do well in this category at 4.13%. Andy and Patrica Loh also won Wildest Partnership with 7.71%; it is not surprising they won Best Game on an upswing. Still this is much less wild than the 9.15% the Kent Hartman and Maritha Pottenger achieved in 2013. In 2014, Kent and Maritha reeled in their wild ride to a sensible 5.48% standard deviation.

Best Attendance is straightforward. Freda Anderson missed only one session in 2014—the day her 2013 attendance award was presented! She shares the 2014 award with Sally Ishihara and Sue Kane.

Last year, I introduced the Payoff Matrix and the examination of pair-pair interactions after factoring in differences in partnership skill, so as to evaluate over- and under-performance. The Best David Partnership and Best Bottom Feeding Partnership awards are based on those results. The Best David Partnership, named for David and Goliath, goes to the partnership which overperforms the most against the stronger half of the field. Sam and Yoko Jordan won this year. Since this award is cast in terms of over- and underperformance, it simultaneously implies they are not beating up as much as they should against the weaker half of the field. The Best Bottom Feeding partnerships goes to the partnership which overperforms the most against the weaker half of the field, and simultaneously underperforms against the stronger half of the field.

For 2013, the Best Pair-Pair Overperformance went to Freda Anderson and Gail Dunham who seemed to “own” Alice Lane and Dorinda Lindvall, doing about 17% better on average than expected over the 17 boards they played against these opponents during the year. This drubbing continued in 2014 but the tormentors slipped to a 13.49% overperformance. My advice to Alice and Dorinda is to try and sit the same direction as Freda and Gail so as not to meet them. My advice to Freda and Gail is exactly the opposite. But in 2014, it was the dynamic pair of Kent Hartman and Maritha Pottenger who held both ends of the Pair-Pair Overperformance awards, performing 18.92% better than expected against Kathleen Hennessy and Tom Tatham and 18.83% worse than expected against Morton and Eileen Heinrich.
