Our friends at the Spanish Chess Problem Society (SEPA) have been trawling through the back issues of The Problemist and identifying all mates in two that were unsound on publication. From that selection they then identified all that had not been subsequently corrected in the magazine. And then they corrected them! The results of their hard work will be published here in small batches, starting soon. View a list of the rescued problems currently posted by selecting The Problems from the menu on the left.
For an introduction (in Spanish) by José Antonio Coello, the distinguished president of SEPA, select Introduction from the menu on the left.
