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. Bg2 Be7 7. d3 O-O 8. O-O Be6 9. Bd2 f5 { the positon would transpose to one that arose via a completely different move order in the game Donnelly-Ireland, Coventry League 1995. 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. Qb3 { is a moot point since after} ({instead the game against David ireland continued with the same plan as was used by Karpov against Romanishin, URS-Tch Tbilisi 1976 and did obtain an edge and an eventual win after} 10. a3 Bf6 11.

Ng5 {Black has here} Bxg5 { (the so-called drawing line for this position as White) showing Bc1-d2 has been a wasted move.}) 4... e4 ({One of the earlier Euwe game's saw the other main Black alternative here of} 4... exd4 5. Nxd4 Bb4 6. Bg5 h6 7. Bh4 Ne5 8. e3 O-O 9. Be2 Ng6 {Reti-Euwe, Olympiad London 1927.}) 5. Nd2 Nxd4 ({Riumin seems to have ventured 1. c4 just once more in a game he lost after the moves} 5...

Bd2 {is a difficut line where Black has yet to justify the loss a pawn.}) 7. g3 Nxe4 8. Nxe4 f5 {This sems to be a novelty that has not been repeated. Its a little loosening but seems fully playable.} (8... Bb4+ { is mostly chosen by Black in this position} 9. Bd2 Bxd2+ 10. Qxd2 O-O 11. Bg2 { an early example was Botvinnik-Flohr, Match Leningrad 1933-without doubt a game that will have been known to both Euwe and Riumin.}) 9. Nc3 Bb4 10. Bd2 O-O 11. Bg2 f4 {This seems to validate Black's choice of 8...f5 as he seems to have a ready made attack if White castles king-side.} 12. Nd5 {Sensibly avoiding the aforementioned possibly especially as Euwe, soon to be World Champion, was already noted as a foremost opening theoretician.} Bd6 {This prevents Black playing d6 and developing the queen's bishop on the c8-h3 diagonal hence safer was} (12... Bxd2+ 13. Qxd2 Qg5 {as compared to the game Black has the possibility of c6 to try and chase away the dominant knight on d5.}) 13. Bc3 Rb8 14. Qd3 (14.

Qxd6 {and White dominates the board.}) 15. h4 {Attractive play-White gains a tempo to advance his attack and then castles on the queen-side into safety. In addition, the dominant d5 knight prevents Black from instigating central action as a means of countering White's king-side attack.} Qh6 16. g4 Nc5 17. Qd2 b6 (17... c6 {now fails to the fork that arises from White advanced pawns.} 18. Nf6+ Rxf6 19. g5) 18. O-O-O {The White king escapes to the queens-side where there is little chance of Black initiating a pawn storm since White controls the centre. 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. Qd3 Nc5 (22... Nxg5 {is no good as White opens all the lines to the Black king as soon as the White pawn reaches the defensive "wall" with} 23. h6 gxh6 24. Rdg1 {with the threats of Rxh6 and Be4 are very strong indeed. However, White should not play the obvious} (24. Qd4 Qg6 25. Rdg1 Rbe8 {and Black hangs on for a whilst.})) 23. 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. Bxf3 {is less forceful as Black limps along with} Bf4 25. Nxf4 ({but not} 25. e3 Bxg5 { and Black is fine.} (25...

Rh4 { Black does not have enough material or compensation for the queen despite the guarded passed pawn on g2 but plays on for a whilst.} Bg5 28. gxh7+ Kxh7 29. Qc2+ Kg8 30. Rg4 Ne6 31. f4 Bf3 32. Rxg2 (32. Rxg2 {giving back some material to simplify into a clearly winning position.} Bxd1 (32... Bxg2 33. Qxg2 Bh6 34. Rxd7) 33. Qxd1 Bh6 34. 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
