Loek plays his favourite bayonet line 9...Nh5 10.Re1 f5 11.Ng5 Nf6 12.f3!? Nh5!?

White postpones the jump Ne6. 15...dxc5 Stellwagen makes a new move. 16.bxc5 Nexd5!

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.

(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.

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.
