The following game is interesting, not only because of the
combinations played to win the game, but especially from the
conclusions drawn about the opening, which contradict  Nunn’s Chess Openings. 
Annotations are by Simon Hradecky.


White : Karasalo,J (2436) - Sweden
Black : Hradecky,S (2200) - Austria

WC27SF10 ICCF Email, 2003 - Opening - Sicilian [B90]

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3 e5
7.Nb3 Be6 8.f3 Be7 9.Qd2 Nbd7

Note my different evaluation to existing opening theory at this position!
Opening theory rates the opening strongly in favor of White, probably
because of the looming 19...Nxb2


10.g4 h6 11.0-0-0 b5 12.Kb1 Nb6 13.Qf2 Rb8 14.h4 b4
15.Ne2 Nc4 16.Bc1 a5 17.Ng3 a4 18.g5

proves no better or worse than main line in opening theory [ 18.Nf5 Bxf5 19.exf5 Qc7
Opening Theory move ( 19...Nxb2 fails badly and loses the game) ]


[ 18...axb3 19.cxb3 hxg5 ( 19...Nxb2 20.Bxb2) 20.Bxc4]

19.Nh5 Bf8 20.gxh6 gxh6 21.Nd2 Qb6

[ 21...Nxd2+ 22.Qxd2] 22.Qxb6 Ncxb6 If the black pawn at d6 can safely advance,
it will create at least two combined passed black pawns in the center, which will
decide the game in favor of Black. Hence White must prevent d5 under all circumstances


suggested move by Fritz 8 [ 23.Bh3 Loses to 23...Rg8 24.Nf1 d5 25.exd5 Nxd5 26.Rxd5 Bxd5 27.Bxd7+ Kxd7 28.Nf6+ Ke6 29.Nxg8 Bxf3 30.Rg1 Be4 31.Ng3 Bh7 32.Nxh6 b3 33.axb3 axb3 34.Nhf5 Bxf5 35.Nxf5 Kxf5 36.Rg8 Bd6]


[ 23...Nc5 24.f4; 23...d5 24.Bb5 Kd8 25.f4]


[ 24.f4 f6 25.Be2 d5]


[ 24...d5 25.f4 f6 26.fxe5 fxe5 27.Ng7 Bf7 28.Rdf1]

25.f4 Nc5 26.f5

[ 26.Rdf1 d5 27.fxe5 dxe4]

26...Bc8 27.Rde1

[ 27.f6 d5]

27...Be7 28.f6 Bd8 29.Be2 Kc6 30.Rg3

[ 30.b3 Be6 31.Rg7 Rb7]


[ 30...d5 31.exd5+ Nxd5 32.Nf3 Bc7 33.Bc4]


[ 31.Rf1 Nbd7 32.b3 d5 33.exd5+ Bxd5]

31...Nbd7 32.Rf1 a3

now clears the field for the decisive attack [ 32...d5 33.exd5+ Bxd5 34.Bc4]

33.b3 Bb6 34.c3 Ba5 35.cxb4 Bxb4 36.Re3 Rhg8 37.Ng7 Bxd2

In the debriefing White mentioned, that he wanted to resign at this point, but then discovered some holes in his analysis and decided to give Black some chances to go wrong

38.Bxd2 Nxf6

the combination, offering two pieces for a rook, prepares the attack d5


[ 39.Rxf6 doesn't save anything 39...Rxg7]

39...Ncxe4 40.Bf3 d5


41.Bxe4 Nxe4 42.Rxe4 dxe4

the three passed pawns in the middle now decide the game

43.Rc1+ Kd6 44.Nc5 f5 45.Be3

[ 45.Bxh6 Rg2 46.Bg5 Rb2+ 47.Ka1 Rh2]

45...Rb4 46.Na6 Rd4


Black : Radecky,S (2200) - Austria

White : Karasalo,J (2436) - Sweden

The combination continues - now offering the exchange in order to
allow the king avoid separation from his passed pawns

47.Nb4 Ke6

The final straw! Now the king can not be separated from his pawns anymore
[ 47...f4 48.Rc6+ Kd7 with the king separated from the pawns White can force Remis ]

48.Bxd4 exd4 49.Rc6+ Ke5 50.Rc5+ Kf4 51.Rc4 Rg1+

It is important to move the rook onto the second line (eyeing the pawn at a2) with tempo.

52.Kc2 Rg2+ 53.Kc1

[ 53.Kd1 fails to 53...Kf3 54.Rxd4 e3 and White can't hold the e-pawn anymore]


Black needs the white knight off b3 to capture the crucial pawn at a2) and can do so
safely as Nd5+ is the only reasonable move of White anyway in this position

54.Nd5+ Kf3 55.Rxd4 Rxa2 56.Kb1

a last tactical attempt to throw Black out of prepared analysis and provoke a mistake,
however the move can not save the game anymore} ({perhaps slightly better is
[ 56.Nc3 Rb2 57.b4 e3 58.b5 e2 59.Rd3+ Kf2 60.Nxe2 Kxe2 61.Rxa3 Rxb5
and White collapses quickly not being able to defend the
h-pawn or grab any of the black pawns]

56...Rb2+ 57.Ka1 e3

Black just pushes through knowing, that queening the e-pawn definitely decides the game by forcing White to give up his rook. Thereafter Black will be able to queen the h-pawn unless White sacrifices his knight for the pawn), whereas the white b-pawn will not reach the conversion field anymore. Black's pawn a3 has reached the end of its useful life.

58.Rf4+ Kg3 59.Rxf5 e2 60.Re5 Rd2 61.h5 Rd1+ 62.Ka2 e1Q 63.Rxe1 Rxe1 64.Nf6

A bit more resistance was promised by [ 64.b4 but even though, White can no longer avoid being mated. 64...Re5 65.Nf6 Rf5 66.Ne4+ Kf4 67.Nc5 Rxh5 68.Ne6+ Ke5 69.Nc7 Rh2+ 70.Kxa3 h5 71.Na8 h4 72.Nb6 Rc2 73.Ka4 Kd4 74.Kb3 Rc3+ 75.Kb2 h3 76.Nd5 Rf3 77.Ne7 h2 78.Nc6+ Kd5 79.Ne7+ Ke4 80.Nc8 h1Q 81.Nd6+ Kd5 82.Ne4 Kxe4 83.Kc2 Qg2+ 84.Kd1 Rf1#]

64...Re5 65.Kxa3

[ 65.b4 Rf5]

65...Rf5 66.Ng8

[ 66.Ne4+ Kf4 67.Nc5 Rxh5 68.Ne6+ Ke5 69.Nc7 Kd6 70.Ne8+ Ke7 71.Ka4 Kxe8 72.b4 Rh4 73.Ka5 Rxb4 74.Kxb4 h5 75.Kc4 h4 76.Kd3 h3 77.Ke3 h2 78.Kf2 h1Q]

66...Rxh5 67.Nxh6 Rxh6

As White needs to move both Pawn and King (otherwise the rook would simply grab the pawn), Black's King can reach the pawn, so that the Rook can safely grab the Pawn. Then a standard endgame King vs. King and Rook results in a quick mate
