He was able to do this as a widely recognised opening authority, at the very least in the UK and Germany to my knowledge, from the 1960s up to the early 2000s. Whether this focus on a wide range of openings in both his theory books and his games, prevented him from becoming not just a very strong GM but a World Class GM is a moot point. It was certainly not helped by the often serious confrontations he had with the "Soviet Authorities".} Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. f3 {The Samisch variation securing White's broad centre but with a small drawback of limiting the options for development of the White king's knight. Often overlooked is the additional fact that f3 makes a subsequent g4 possible as part of a White attack that may also involve h4.} e5 {Black strikes in the centre even before castling whilst the same idea can be played after castling with} (5... O-O 6. Nge2 e5) 6. Nge2 {Keeping the tension in the centre. The main alternative is} (6. d5 {closing the centre when play usually goes} Nh5 7. Be3 f5) (6. dxe5 {is nothing special for White as after} dxe5 7. Qxd8+ Kxd8 {Black can follow with c6 when the king would be quite comfortable on c7.}) 6... O-O 7. Bg5 {As the king's knight has been developed early to e2 White takes the opportunity to develop the bishop to an active square. Instead if} (7. Be3 {the opening transposes to the common lines which arise if 6.Be3 had been played instead of 6.Nge2. Black then has the flexible move} c6 {available with a very playable game after} 8. Qd2 Nbd7) 7... c6 8. Qd2 Re8 {A relatively rare move in this position which doesn't achieve much in terms of pressure on the e-file unless Black can also open the game with d5. White's next prevents this option. In later years highly rated players favour the aggressive} (8... Qa5 {one recent example being Moiseenko-Kovalev, Dresden ZMD op 2010. This queen move was remarkably deeply researched in the fifties, thus about the time the main game was played, according to Cherniaev and Prokuronov in their 2007 book.}) ({and most preferably the flexible} 8...

White's attack is well under way and his king is simply not on the queens-side to be attacked if Black should be able to play b5. Later in the game White played Rc1 and left his king safely in the centre.}) 10... c5 ({Opening the c-file with} 10... cxd5 {is not promising for Black after} 11. Bxf6 Bxf6 12. Nxd5 Qd8 (12...
