Happy you are finding it useful. It's one of our best-selling books and deservedly so.

I would prefer to keep this area for discussing Gambit books. Viktor and I may have disagreed about some openings, but I respected him and was saddened by his death.

Detailed analysis of even one major opening is enough to fill a large book so to cover all openings would be impossible in a single volume. The out-of-print Nunn's Chess Openings was perhaps the closest, but that is quite out of date.

You need to download our free app called Gambit Chess Studio 2, which allows you to buy this and many other Gambit books in app format. There's a free sample if you want to try it out before you buy a book. Our web page www.gambitbooks.com/webapp2/HowToUseApp2.html explains how to use the app.

@@gambitpublications618 I only buy interactive titles that run on Windows. Is a Chessable version of FCO planned? I'd actually prefer it in Chess Studio, though, as Chessable is pricey and IMO this is a book to read and understand rather than train. I've seen in the Chess Studio FAQ that no Windows version of it is planned. I wonder if you think using an Android or iOS emulator is a good idea, and if so could you recommend one that works well with your app and is lightweight?

​@@bluefin.64 We do not plan a Chessable version of FCO. While we do not officially support Android emulators for Windows, in practice we have had no problems using the BlueStacks Android emulator with Chess Studio. I suggest you try it with the free sample first!

It's readable, but you have to use an actual board and be able to read chess notation with it, as you experiment with your chosen openings. The problem with MCO-15 is that it's mostly tables and has what feels like endless variations (Ruy Lopez and Sicilian Defense), And past games... It's also outdated, considering the online opening databases that exist nowadays. I keep mine for reference; my go-to for openings are Kaufman's New Repertoire for Black and White(2019) yeah the newest version) and I use Nigel Davie's Gambiteer 1 & 2.... I want FCO for my son, though. That's why I'm watching this review....to keep him away from MCO-15 LoL😊

I don't think so. The book focusses on ideas and plans rather than concrete variations, and these hardly change over the years. It's still one of our best-selling titles and justifiably so.

@@gambitpublications618 What do you think about chessbase opening encyclopedia compared to the book?

I can't comment on items produced by another company.

Would you recommend this book for club level players? Most opponents I play against doesn't know much theory.

Yes, it's ideal for club-level players since it focuses on general ideas and avoids very detailed analysis which is often irrelevant for club players.
