Play might, however, lead to a position where White achieves a reversed Sicilian with a move in hand but that is not pre-ordained as Black can make moves to avoid such a line if this is a concern. Even if this occurs matters are not so clear as indicated in the game's notes given at move 4.} 2. Nc3 Nc6 3. Nf3 Nf6 {The English Opening variation termed, unsurprisingly, the Four Knights variation. Euwe had used as White, and faced as Black, this line several times before the current game. It is interesting to note that Riumin was a 1. e4 or 1.d4 player prior to, and for the earlier part of this event, although he did play 1.c4 later against Checkov and Botvinnik in later rounds at Leningrad. Possibly Riumin prepared 1. c4 specifically for this event and maybe even for Euwe himself.} 4. d4 {A forcing variation although White may play other lines such as 4. e4, 4. e3, 4.d3 or one of the most popular moves} ( 4. g3 {when after} d5 5. cxd5 Nxd5 6.

It is now actually a Reversed Dragon in which White has the extra move Bd2 compared to the equivalent position as Black. In addition, it is now White's move but whether he has any significant advantage after the standard (Black) reply:} 10.

In addition the White queens-side, especially the b2 pawn, is securely defended.} Bb7 19. g5 {Gaining another tempo for the pawn attack. In contrast Black's rigid queen's-side set up, whilst fine in itself, does not allow Black to counter-attack against the White king.} Qe6 20. Qd4 Qf7 21. h5 {The pawns creep forward and Black cannot "get behind" them to take advantage of the holes in White's game and attack the White king, the usual recipe to mitigating this sort of attack, as the White king is not there but on the queens-side!} Ne6 22.

Qd2 f3 {A desparate resource but dismissed by White who simply continued to push forward the pawns.} 24. g6 { Both sides have managed to advance a pawn to the sixth rank. However, White is the more meaningful since lines can now be opened against the Black king thus allowing the White pieces to endanger the Black king. In contrast Black's pawn advance although also opening some lines has less relavance sine the White king is not in residence on that side of the board hence the Black pieces are not able to generate serious threats to the White king.} (24.

Qxd7 $18 {A game Black lost because he was not able to exploit the "holes" in White's position that arose from the advance of his king-side pawns on the kings-side. Firstly, because the White king was simply not in residence on that side of the board and hence vulnerable. Secondly, because Black was unable to generate any counter-play either on the queen-side or in the centre to negate White's own pawn advances. Although both sides managed to advance a pawn to the sixth rank White's was more meaningful since it allowed White to open lines to the Black king.}) 1-0
