There’s a site that covers some prolific chess authors (IMHO) such as:
(a) Reinfelds, F. – 1001 Brilliant Way to Checkmate & 1001 Winning Chess Sacrifices
(b) Polgar, L. – Chess 5334 Problems
(c) Chernev, I. – Winning Chess Traps
(d) Alburt, L. – Chess Training Pocket Bk: 300 Most Important Positions & Ideas
They can be found at: http://mysite.verizon.net/webmasterfrank/patterns/books.htm
There’s also a list of other PGN & PDF books (some of which are at the download page of Chess.com).
The Java script is truly horrid & it will freeze ever so often. Then, there're days nothing will show. If you reach that stage, you’ll probably have to reboot or come back later.
PLS NOTE: Free sites such as the above-mentioned are renowned for bugs, hence do ensure you’ve Anti-Spyware.
Other than that – it’s still a cool place to checkout.
Hope this is of some help to some folks.
