Kotov - Science of Strategy

The English Opening is very popular nowadays, but 1.c4 e5! is a serious challenge and not to everyone's taste. Here comes 1.Nf3, with the idea to transfer the game into the English with c2-c4 to follow. The only hurdle on that path is 1...d5. Then White is at a crossroads. 2.c4 allows 2...d4 3.b4, while 2.e3 is an attempt to deny ...d4. Black can revive the threat with 2...c5, and again, White has a choice. 3.c4 d4 4.b4! leads to the Blumenfeld with reversed colours. Or he can continue to fight against ...d4 with 3.b3. White's decisions on the second and third move depends on the way he wants to meet the Queen's Gambit and the Slav/Meran/Chebanenko. Semkov covers in detail the different options, and also devotes several chapters on 1.Nf3 d5 2.e3 Nf6 3.c4 c6 and 3...e6 4.b3! (avoiding the innocuous version of the QGA after 4.Nc3 dxc4). There is another chapter on 1.Nf3 d5 2.e3 Nf6 3.c4 dxc4, where the absence of Nc3 allows White to get some pressure by refraining from d2-d4.   244 pages

Everyone knows that the Petroff is one of Black's most solid options to King's Pawn openings, which has endured for centuries. Most people DON'T know that the Damiano Variation - a subset of Petroff - is equally sound and not a beginner's trap into which we fell. The lines of the Damiano may be tailored from the same cloth as Petroff, yet they are quite different. One "Damiano-is-bad" critic wrote on my page: "...selling the Petroff Damiano line as a sure-fire draw for Black seems to me to be overselling it." Actually, incorrect. You CAN hold a draw with the Damiano if you are willing to put in some work of learning the critical lines and the defensive ideas. When I began to look deeper into the line, I came to the shocking realization that there is zero reason to believe in the "refuted" verdict since the engines are on the Damiano's side, not White's! 235 pages
