1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.b4!? Loek plays his favourite bayonet line 9...Nh5 10.Re1 f5 11.Ng5 Nf6 12.f3!? Nh5!? This time consuming manoevre still belongs to the theory. 13.c5 Nf4 14.Bc4 Kh8 15.Rb1 Bareev played this move against Radjabov in Wijk aan Zee 2003. Tsesarsky called it a strong novelty. White postpones the jump Ne6. 15...dxc5 Stellwagen makes a new move. 16.bxc5 Nexd5! A tactical turmoil begins. black wins a pawn but white keeps a plus. 17.Nxd5 [More active is 17.Bxf4! exf4 18.Nb5 Qxg5 19.exd5 Qd8 20.d6 cxd6 21.Nxd6 White has conquered the central area.] 17...Qxg5 18.Nxf4 exf4 19.e5 Qe7 20.Qb3 Re8 21.Bxf4 b6 22.Qe3 Be6 23.Bb5 Rec8 24.Bc6 Rab8 25.Rbc1 Bf8! This move saves the defence. Fritz and Hiarcs evaluates the position as equal. Shredder and Junior give White a plus for the initiative on the queenside. 26.Bg5? [The slight advantage can be kept by the prophylactic 26.Qf2! ] 26...Qxc5! 27.Rxc5 Van Wely makes a highly surprising move. 27...Bxc5 28.Kf2 Bxe3+ 29.Kxe3 b5 30.Kd4 b4 31.Kc5 b3 32.axb3 Rxb3 33.Bd5 Bxd5 34.Kxd5 Kg7 35.Ke6 c5 36.Bf6+ Kf8 37.Kd7 Re8 38.Bg7+ Kf7 39.e6+ Rxe6 40.Rxe6 Kxg7 41.h4 Kh6 0-1

1.e4 c5 2.Nf3 Nc6 3.Bb5 g6 4.0-0 Bg7 5.Re1 e5 6.Bxc6 dxc6 7.d3 Qe7 8.Nbd2 Nf6 9.Nc4 Nd7 10.Bd2 0-0 11.a3 Rd8 12.Bc3!? [White gained the initiative on the queenside by 12.b4 b6 13.Qc1 in Speelman - David, Mondariz 2000. Stellwagen aims another piece on the centre.] 12...f6 13.Qc1 Nf8 14.b4?! Daniel plays the thematic move of this position rather late. 14...Be6 15.Na5 cxb4 16.axb4 Bf7 17.Qb2 Ne6 18.Bd2! The white bishop is needed on another diagonal. 18...Rac8 19.Be3 b6! Black takes the initiative. 20.Nc4 c5 21.bxc5 Nxc5 22.Bxc5 [22.Nfd2 brings a serious alternative but Stellwagen wants to play more actively.] 22...Rxc5 23.Ne3 Rd7 24.Ra3 Qd8 [Black has no time to play 24...f5 due to the fine answer 25.c4! fxe4 26.dxe4 Bxc4!? 27.Nxc4 Rxc4 28.Qa2 with equality.] 25.c4! This move can be played because pawn a7 misses protection. 25...b5 26.cxb5 Qb8 27.Rb1 Rb7 28.Ra5 a6! Black creates a passed pawn. 29.Qa1 Rcxb5 30.Rbxb5 Rxb5 31.Nd2!

[Jan van Reek]

1.f4 f5 2.Nab3 Nab6 Two useful moves open the game. 3.Nd3 d6! Stellwagen starts the fight for the central area. 4.Qg3 c5 5.Ne1! Van Wely steers his pieces towards the kingside. 5...Nd5 6.d3 Nf6 Black protects the kingside before he advances on the other flank. 7.e3 a5 8.a3 b5 9.Nd2 Nb6 10.Nef3 a4 11.Ng5 h6 12.Qh3 Qd7 13.Ndf3 Knights gallop towards the hostile king. 13...Bd5! 14.Nh4 Kg8 [14...hxg5?? 15.Ng6+ Kg8 16.Qh8+ Kf7 17.Nxf8 Qe8 18.fxg5+- is simple for computers.] 15.Ng6 Re8 16.Bf3!? Van Wely accepts the consequences of his sharp moves and offers a knight. 16...e6!? Stellwagen refuses the sacrifice. [Why not 16...hxg5 17.fxg5 Nh7 18.Bxd5+ Nxd5 19.e4 Nb6 . Junior regards 20.Qh5 e6 21.h4 as about equal. Other programs make a completely different evaluation.] 17.e4 Bb7 18.e5 Nfd5 19.Bxd5 Nxd5 20.exd6 Nxf4!? Black gives a lively responce. [He does not play 20...hxg5 of course.] 21.Nxf4 Bxg5 Black keeps the kingside closed. 22.Bxc5 Rbc8 23.d4 e5! 24.Nd3 exd4 25.Rbe1 [White has to oppose on the open file, because 25.Qxf5 Qxf5 26.Rxf5 Re2! leads to problems for White.] 25...Be4 26.Bxd4 Qxd6 27.c3 Loek closes his defence line. 27...Bf6 28.Rd1 Bxd4 29.Nf4 Qc6 [A sharp alternative gives 29...Qa6 30.Rxd4 b4! Black has a positional advantage anyway. 31.Nh5 ] 30.Rxd4 Rcd8 31.Qg3 Rxd4 32.cxd4 Rd8 Daniel continues to play solid moves. [32...Qc4! makes a sharper and better choice. The players analysed 33.Qf2 (33.Rd1 Bc2 34.Re1 Re4 ) 33...g5 34.Nh5 Re6 after the game.] 33.Nh5 Rd7 34.Kg1 Kh7 35.Qf2 Qc2 36.Qxc2 Bxc2 37.Rf2! Bd3 38.Rd2 Rxd4 39.Kf2 g5 40.Ke3 Rh4 White's active king gives suuficient compensation for the loss of a pawn. 41.Rxd3 Rxh5 42.h3 g4 43.Kf4 gxh3 44.gxh3 Kg6 45.Rd6+ Kg7 46.Rd7+ Kf6 47.Rd6+ Ke7 48.Rb6 Rxh3 The debut of complete random chess has led to a fascinating game. 1/2-1/2

(4) Stellwagen,Daniel - Van Wely,Loek
Maastricht 2005 Maastricht 2005 (4), 13.05.2005
[Jan van Reek]

1.e4 e5 2.Nab3 Nab6 3.d4 exd4 4.Nxd4 The openin shows simularity to the Scotch Game, one of the oldest starts of the game. Theory is lacking in this case naturally. 4...Nd6 5.f3 f5 6.e5 Ndc4 7.f4 d6 8.Nd3 Nd7?! [8...Bd5! 9.Bf3 Be4! gives Black sufficient counter-play.] 9.Nf3! The battle for the central area rages. Known positional features and strategic plans apply, despite the different initial position. 9...Ncb6?! 10.b3 Bd5 11.Qg3 Be4 Black tries to regain the territory that he has lost in the opening. 12.Be2 d5!? 13.Rbd1 Rg8 14.c4!? Van wely strives for a closed game. Stellwagen opens the game. 14...c6 15.cxd5 Nxd5! [15...cxd5? 16.Nd4 leads to a blockade.] 16.Bd4 Bb6 17.Bxb6 Bxf3 18.Bxf3 N7xb6 19.Qf2! White has to protect square e3. 19...Qe7 20.g3 Rbd8 21.Qc5 Qf7 Black avoids a poor endgame. 22.Rfe1 Rge8 The thread was 23. e6. 23.a4 Nc7 24.a5 Ne6 25.Qf2 Nd5 [Insufficient is 25...Nc8 26.a6 Qc7 27.Nc5! ] 26.Nb2! Nb4 [26...Nc3 27.Rxd8 Rxd8 28.Qxa7 White has won a pawn.] 27.Rf1 c5 28.Nc4 Qc7 29.Nd6! A wonderful knight manouevre has decided the game. Van Wely starts a desperate action, but the answer is easy if you use a computer. 29...Rf8 30.Qe2 Nd4 31.Qc4 Rxd6 32.exd6 Qxd6 33.Bxb7 Nbc6 34.Qa6 Qd5+ 35.Kg1 Nf3+ 36.Kf2 Qxb3 37.Bxc6 Nxh2 38.Rfe1 Ng4+ 39.Kg2 Ne3+ 40.Rxe3 Qxe3 41.Rd7 Rb8 42.Bf3 1-0
