While incorporating the new Bogota crosstable into my own page, I noticed a discrepancy between the old and new clippings. The reference for the new clipping explains this in some detail (translated from the original Spanish by Google):-
Among the various sources used to reconstruct the tables of results of the FIDE Zonal 7 - Bogotá 1972, there are discrepancies in the number of players, creating variations in the final score. In the journalistic report JAQUE magazine (01-09-1972, page 38) are registered only 16 of the 17 participants (Trotsky Yepez not shown) and the following explanation:
"There was regrettable withdrawals Ecuadorian TROZKY YEPEZ (SIC), illness, when he had 2 points from 7 possible and Venezuelan CARO when he had 4 points 8. (This last figure in the box classification having played more than 50 percent of the items, according to FIDE rules)."
The new Santana pages are on domain ajedrecito2.galeon.com. The links I used for 'Caracas Zonals', on ajedrecito.galeon.com, are not working ('Lo sentimos, esta página no existe o no está disponible') and I'm not sure why. Thanks again, Rafael, and I hope we can soon see all of your pages again.
