16.Bh7??
 

A natural looking move, however the decisive mistake, loosing a valuable
tempo to defend against the threat of Bxh3 and therefore loosing the wholegame
[>=16.Kh1 Be6 17.Na3 Qc8 18.Qh5 Nd7 19.Rg1 a6 20.Be3=]

16...Rg7-+ 17.Be4

[probably better is 17.Qd3 ]

17...Bxh3 18.Bxh6 Rg8 19.Na3

[more resistance and some counterplay promised 19.Re1 Bg4
20.Bf3 Bxf3 21.Qxf3 Rg6 22.Be3 0-0-0 23.Nd2 Rdg8 24.Kf1 Rxg2-+]

19...d5 20.Bf3 Bh2+

all black forces already eye White's king, now the final attack launches.

21.Kh1] Bxg2+ 22.Bxg2] Rh8 23.Qb5+

[slightly better is 23.Nb5 Qe5 24.Qxe5 Bxe5 25.Kg1 Rxh6
26.f4 Bb8 27.Rad1 e6 28.f5 a6 29.Nd4 Bh2+-+]

23...Nd7 24.Rfd1 Rxh6 25.Rxd5 a6 26.Qe2 Ne5 27.Rad1?

trying to confuse the opponent? [much better is 27.Rd4 e6 28.Nc2 Ke7]

27...e6 28.R5d4?

enabling a beautiful final combination by Black [significantly better is
28.Rxe5 Bxe5+ 29.Kg1 Rh4 30.Qd3-+]

28...Ke7

Black needs both rooks at the king side for the final blow

29.f4

[29.Nc2-+ a feasable alternative]

29...Rg8 30.f5

[30.fxe5? looses the Queen on top of all pain 30...Bxe5+ 31.Kg1 Bxd4+
32.Rxd4 Qh2+ 33.Kf1 Rxg2 34.Qxg2 Rf6+ 35.Ke2 Qxg2+ 36.Kd3]

30...Qc6!

 



this queen sacrifice, vary rare in correspondence chess of this level anyway, sends
the strongest possible message to the opponent, that he's lost the game.
White promptly resigned. [30...Qc6 31.f6+ (31.Bxc6 Bf4+ 32.Qh2 Rxh2#)
31...Kxf6 32.Rf1+ Ke7 33.Nc2 Rg7-+ 34.a3 Qc8 35.Qe4 f5 36.Qh4+ Rxh4 37.Rxh4 Bg3
38.Rh3 Nd3 39.Nb4 Nf2+ 40.Rxf2 Bxf2 41.Nd3 Qe8 42.Rh6 Qa4 43.Nxf2 Qc2
44.Rh7 Rxh7+ 45.Kg1 Qc1+ 46.Nd1 Qxd1+ 47.Kf2 Qd2+ 48.Kf3 e5 49.b4 e4+
50.Kg3 Rg7+ 51.Kh4 Qh6#]

0-1
