<1.e4 g6 2.d4 d6 3.Nc3 Bg7 4.f4> This is called the Robatsch: Pseudo-Austrian attack. <4...Nc6 5.Nf3 Bg4 6.Be3 Bxf3 7.Qxf3?> An opening inaccuracy, losing grip on d4. The right move here is 7.gxf3. <7...Bxd4 8.Bxd4 Nxd4 9.Qd3 e5!?> Crafty prefers 9...c5. <10.Nb5?> Probably White was thinking something along this line: 10.Nb5 Nxb5 11.Qxb5+ c6 12.Qxb7. However, Black has a better defense and this attack proves to be immature. Better for White would have been to first get the defense in order by 10.O-O-O. <10...Ne6?!> Although this attacks White's f-pawn, Crafty prefers 10...Nc6 <11.f5?> This might look like it's pressuring Black, but while White is "attacking" and Black is "defending", Black's troops are only building while White's structure is collapsing. Better here would have been 11.fxe5 dxe5 12.Qd5 <11...Nc5 12.Qd5??> I don't get the point of this move at all. Is White seriously believing this can pressure Black? <12...Nf6 13.Qc4 c6 14.Nc3> A painful retreat of White's forces. White has achieved nothing with the "attack" and is now behind in development. Also, White's kingside pawns are extremely weak. <14...b5 15.Qe2 a5?> This is too enthousiastic. Black must also mind defending all these advanced pawns. <16.O-O-O b4 17.Nb1> Not a pretty square for White's knight. <17...Nfxe4 18.fxg6 fxg6?> A wrong strategical choice. Crafty prefers 18...hxg6 and I think Crafty is right. Black was planning to castle short here but the king is poorly defended when it is on g8 and is shielded by the pawns on d6 and e5 that are under quite some pressure. As we will see Black will have some problems resulting from this. <19.Nd2 Nxd2?> 19...d5! 20.g3 O-O would have been better for Black. <20.Rxd2 O-O 21.g3> Planning Bg2 and destabilizing pawn's structure <21...a4?> A mistake. This loses the b-pawn. Crafty suggests here to sacrifice one pawn with 21...d5 22.Qxe5 and keep a solid pawn structure. Another interesting option is 21...Qe7! <22.Qc4+ Kg7 23.Qxb4 Qg5!> Black's finest tactical move of the game. This move completely gives Black the initiative. <24.Bg2 Rf2! 25.Rg1 Rxd2> Here Black missed a beautiful deep move. 25...a3!! Now if 26.bxa3? then 26...Qe3! 27.Bxc6 Rxd2 28.Qxd2 Qxg1+ 29.Qd1 Qxd1 30.Kxd1 Rxa3 winning a rook. The point of 25...a3 is that now 26...Qe3 is unstoppable. If 26.Qe3? then 26...Na4! 27.Qb4 Rb8! winning the Queen or White will eventually get mated. (28.Qxb8? 29.Qxd2). Of course, Black cannot really be blamed for finding these beautiful combinations.

<26.Qxd2 Qxd2+ 27.Kxd2> Exchanging material, hoping to win the game with the advantage in material. <27...d5 28.Re1 e4 29.Kc3 Ne6 30.Bh3?> White is pursuing its tactics of "chasing around Black's pieces" again. This time, it will prove to be fatal for White. <30...Ng5 31.Bd7 Nf3!> A fine move that serves multiple purposes. It attacks the rook on e1, it attacks the pawn on h2 and it enables 32...d4+! <32.Rh1 d4+ 33.Kc4?> The move that loses the game. <33...Ne5+! 34.Kxd4 Nxd7 35.Kxe4 Rf8 36.Kd3 a3!> Now if 37.bxa3? then 37...Rf3+ followed by 38...Rxa3. <37.b3 Nb8> Planning Na6, Nb4 attacking Black's pawns on a2 and c2. <38.Kc4 Rf2 39.Kb4 Rxc2 40.Kxa3 c5!> This enables 42...Nb4 two moves later so that the king cannot capture the knight while Black's pawn on a2 is attacked. <41.h4 Na6 42.Rd1 Nb4 43.Ra1 Rg2> More of White's pawns are bound to fall. White resigns. 0-1

"Here Black missed a beautiful deep move. 25...a3!! Now if 26.bxa3? then 26...Qe3! 27.Bxc6 Rxd2 28.Qxd2 Qxg1+ 29.Qd1 Qxd1 30.Kxd1 Rxa3 winning a rook. The point of 25...a3 is that 26...Qe3 cannot be prevented by 26.Qc3. If 26.Qc3? then 26...Na4! 27.Qb4 Rb8! winning the Queen or White will eventually get mated. (28.Qxb8? 29.Qxd2). Of course, Black cannot really be blamed for finding these beautiful combinations."
