US Open 1997 – The Strange Case of Multiple Entries

Here is a very informative post with tournament details by <Phony Benoni>:

Phony Benoni: <zanzibar> So far I am not seeing a lot of those games in the bulletins, but it’s hard to tell. There were six (!) different playing schedules:1) Traditional. One round per day from 7:00 PM – 12:00 AM.Rds 1-6 Sunday 8/3 – Friday, 8/8
Off day Saturday 8/9
Rds 7-12, Sunday 8/10 – Friday 8/82) Early Bird. Same as Traditional, except that rounds 1-6 were played in the earlier in the day. Popular with older players who don’t like to stay up late. Merged with Traditional in round 7.

3) Early Bird / Traditional Best Ball. You could play in both sections, then keep your best score for the second week. A woman named Alina Markowski (#354 and #515) did this, and had the distinction of losing to both Irina Krush and Jennifer Shahade in the first round. And both games made the bulletins! Auggh!

4) Busy Person’s Schedule. Received byes fin rounds 1-6 based on rating. Merged with Traditional for round 7.

5) Eight Day Schedule.
Rds. 1-8: Two games daily, Friday 8/8-Monday, 8/11
Rds. 9-12: Merged with Traditional

6) Five Day Schedule
Rds. 1-5 Monday, 8/11, at a fast time control
Rds. 6-8, Tuesday 8/12, at fast time control, during the day Rds. 9-12: Merged with Traditional, starting Tuesday evening

The bulletins do a good job of separating the sections, but the result is that games for any particular round can pop up in three different bulletins.

Now, <Phony> mentions a duel track, double entry, select best mode he calls “Early Bird / Traditional Best Ball“. I think this (almost) explains the duplicated player entries I found in the USCF Swiss xtab:

480 512  Angel, Antonio
466 504  Ashbaugh Jr, Douglas Leroy
505 525  Borders, Ronald A
483 516  Bowen, Donald E
343 520  Caplan, Scott
 58 464  Celorio, Edward J
403 514  Doredant, Richard
446 532  Eamus Jr, D J
138 526  Hayes, Rea B
122 429  Kahane, Gabe
 19 463  Kaufman, Lawrence Charles
354 515  Markowski, Alina F
239 465  Rubenstein, Jeff
234 534  Schadler, Peter F
136 503  Schreiber, Edwin Z
 22 502  Shahade, Greg
262 521  Spencer, James
270 510  Wheeler, Jerry T

The numbers on the left are the index (or placement) index numbers found on the USCF Swiss. There are eighteen players who elected for this mode. The lower numbered entry always shows the complete tournament, and reflects the player’s record after dropping the section with the lower score.

We can then look and compare the multiple-entries for these double entered players to see which of their two entries was keep for the 2nd half of the tournament:

As one can see, Alina F Markowski shows up, as expected given <Phony>’s mention.  What I don’t understand, is how some of these double entries have the second entry with more than six games (or, if you read <Phony>’s week as literal, seven). Here’s a list of number of games played in the dropped entry to show this more clearly:

6 Angel, Antonio
5 Ashbaugh Jr, Douglas Leroy
5 Borders, Ronald A
7 Bowen, Donald E
5 Caplan, Scott
5 Celorio, Edward J
5 Doredant, Richard
3 Eamus Jr, D J
1 Hayes, Rea B
7 Kahane, Gabe
6 Kaufman, Lawrence Charles
6 Markowski, Alina F
8 Rubenstein, Jeff
1 Schadler, Peter F
5 Schreiber, Edwin Z
4 Shahade, Greg
5 Spencer, James
4 Wheeler, Jerry T

It looks as if 5 is the most frequent number played. It could be understandable that a player drops out early if it’s clear which their score will be lower in one section versus the other. But what about the entries with 7 games, or 8 in the case of Rubenstein?

And what to make of both Hayes and Schadler each having but one game?

Note that an accurate cross-section must include the duplicate entries, to reflect the score of opponent. This means that there will be double entries for some number of these 18 players in a given round – unless I can somehow determine who played in the morning sessions vs. the evening sessions, and am able to differentiate.

Running a tournament like this makes accurate book-keeping very difficult.
