Both are good books. I would say that My System is more advanced than Simple Chess. Simple Chess is a nice introduction to positional/strategic ideas, and is a pretty quick read. Being a Dover publication it is cheap as well, something like $9.95.
I'm not sure which is the best edition of My System. Quality Chess recently came out with a new edition that has gotten both good and bad reviews. I believe Hays Publishing also came out with a 21st century (algrebraic) edition a while back. McKay or someone used to have a descriptive notation edition. The Quality Chess edition is a nicely put together book, but I can't speak to the quality of the translation at this point.
The other day someone told me that My System was the best book he owned.
I have also heard that Simple Chess by Steans is great.
Now my rating is a somewhat slippery 1325, and I wonder how you would compare and rate the two books for someone around that rating.
Also, which edition of My System is the one to get?
Which should I get? SC or MS? Both? Neither?
I'd like your thoughts please as I know so many of you have read these books.
Thanks.
