I’ve heard lots of stories alleging poor TD behavior. I’d like to think I haven’t personally exhibited it.
(Actually, I know I have occasionally been short with players. That may happen at larger events, and the people fall into one of two categories: people who come to me with belligerent attitudes, or people who ask the same questions repeatedly.)
The following are stories where I witnessed what I would call inappropriate behavior first-hand, or was given first-hand recollection.
I was told of a TD in Northern Illinois who, back in the days of pairing cards, was having trouble making a legal set of pairings. Several times, he’d pair the round, only to have a pair of opponents inform him that they’d previously played. Finally, in exasperation, the TD just told everyone to move one chair to the left.
In 1992, I did once arrive at a tournament where I was supposed to be on staff, about 2 hours before the start of the first round. The site was locked up, and no one was around. Players started arriving about 30 minutes after I did…but still no one there to open the site. The organizer (who was also the chief TD) finally arrived 5 minutes after the scheduled first round start time. Why was he late? He had to make bail.
Anyone who was in the St. Louis area in the late 1980s or early 1990s can attest to the numerous examples of poor behavior on the part of two influential warring NTDs, which unfortunately extended to the organizers and directors who aligned with each. Thankfully, this was pre-social media.
About 10 years ago, I was hired as the pairing chief for a scholastic tournament. When I went to make the last round pairings, the organizer - whose son was playing in the section I was about to pair - decided he would make the last-round pairings himself. I subsequently refused to sign for or be listed on the rating report. A year or so after this, that same organizer/TD was assigned to work with me in a national tournament. I ended up doing almost all the work in my section - because he spent his time watching his son’s games.
In 1990, I was at a tournament where I watched a TD do prize calculations. This TD simply decided that he didn’t need to pay a particular class prize, because the winner of the prize was the only player in the class, and the TD did not like that player. So, the TD simply combined classes where he wouldn’t have to pay the winner. This combination was not in any pre-announcement, nor was it so much as brought up during the event.
About four years ago, I watched a TD adjudicate a scholastic game with K+B+N vs. K as a draw. The players had just gotten to that material balance. The inferior side was a student of the TD (who is certainly a sufficiently strong player that he realizes the ending is a win, though the superior side may well have been unable to win it within 50 moves).
I was traveling on business back in 2006, and was asked to help with making pairings for a one-day tournament I had planned to enter. Apparently, the only certified TD in the area had enjoyed a significant number of nightcaps, and showed up for the event displaying visual and olfactory artifacts of same.
At a side event for the London Chess Classic in 2012, I saw an arbiter threaten to throw a player out of the concurrent FIDE Open, simply for talking too loudly in the playing hall. The subsequent disturbance, naturally, was much louder than the player’s initial talking. Further examination revealed that this arbiter and player had a long and contentious history. Even so, however, I did privately tell the arbiter that I wasn’t sure FLC 13.4 covered him if this was the player’s only offense in this particular event.
During last year’s Bunratty Chess Festival, while walking through the site, I bore witness to a cheating complaint in one of the lower sections. The arbiter who handled it, unfortunately, did not keep control of the situation, and a rather ugly three-way shouting match developed. I eventually stepped in to suggest that the discussion be adjourned to the hallway. (I wasn’t working as an arbiter, but the arbiters knew who I was, thanks to my friendship with the chief arbiter.)
