Modern Chess Opening vols 1-7

I have always purchased the latest edition of the the one volume chess book Modern Chess Openings.  I do this mostly to make sure that my opening repertoire doesn't have any major holes in it and is fairly up to date.   Today I noticed something called Modern Chess Opening vols 1-7 on sale.  Please tell me this has nothing to do with Modern Chess Openings.

It is unrelated.

you can breath now blake78613 is all good news.

Modern Chess Opening Set 1-7 is probably a computer program created by the Russian GMs Kalinin and Kalinichenko not a book by American GM Nick De Firmian.

Fischer used to quote from Freeborough and Ranken's Chess Openings Ancient and Modern which was first published in the 1890's.  Old books can be kind of interesting just to see what used to be popular.  I probably have copies of Reuben Fine's Modern Chess Openings 6th edition (1939) and Practical Chess Openings (1943) kicking around here somewhere.  If Morphy ever is transported through time, I want to be ready...

I used to have MCO 2, 6-current. I divested myself of most of them in one of my periodic bookshelf purges, but I kept 2 and 6 and 10.

#10 (Evans) I will always keep as it was my first serious chess book as well as a great revision in its time.

#6 was edited by Fine and may be the greatest MCO in terms of impact and quality.

#2 dates from 1914 and is fun to refer to for old double KP lines and cites games by the young bucks like Capablanca.

Those early MCOs, up to #6, were small form factor and genuine pocket books that could be carried with you without problem in a coat pocket.

I purchased Fine's Practical Chess Openings, and used it for many years.  I later purchased MCO 10, but preferred the lines in PCO even though they weren't as current.  The PCO lines were very solid and kept me out of trouble and into a decent middlegame.
