I tried many links and most are down. Also not sure why you allow these dangerous money making links on your site. Some links just take you to another money making link to get the real chess stuff or even a direct link using the normal zippy, soldifiles, etc. These money making links are just useless with time delays, dangerous ads and viruses and just give the person money for you clicking on their links. Also most of the links are just very old books that can be found anywhere on the web for free with not going through all these obstacles. And most just point to the real link from the biggest free chess site immortal.
