★★★★★ SeVeN 7 · Oct 15, 2020
It's nice, and I hope in the future there will be "Chess tactics in English Opening". Because I like the English Opening and want to study more.
★★★★★ Andrea Spletstoser · May 31, 2022
This covers alot of what you will see in openings, and you can get alot out of it, but it takes time to digest the vast amount it covers. It's been a great aid to my chess and developing my pieces in the right way. Highly recommend!
★☆☆☆☆ Mido Maged · Aug 19, 2021
Not the perfect opening manual as described and nit free either. The only free component is just a small part and doesn't include important opening, while the rest are paid and quite expensive too!
★★☆☆☆ Thomas Allein · Nov 24, 2020
Far from perfect. Difficult to use. The theoretical material is huge, but is badly organized. I thought it would look like a reference source, but it is unsuitable for that. Even Wikipedia is much better, more handy than this. Maybe good for puzzle-solving though.
★☆☆☆☆ Chris Sullivan · Sep 17, 2023
Ripp off. The only free content is worthless.
★☆☆☆☆ Tibor Juhasz · Jul 9, 2023
I los5 against Carlsen. Did not work for me.
