Round 6 [we]


1.e4 e6 2.d4 d5 3.Sd2 Sc6 4.Sgf3 Sf6 5.e5 Sd7 6.Le2
[Another theoretical line is
6.Ld3]
6...f6 7.exf6 Sxf6
[7...Dxf6 Wird haeufiger gespielt als Sf6:
8.Sf1 Ld6
(8...e5 , but it has a reputation of extremely dangerous continuation for black:
9.Se3 (9.dxe5 Sdxe5 10.Dxd5 Le6 11.Db5 a6 12.Da4 O-O-O 13.Sxe5 Dxe5 14.c3 Lb4 15.cxb4 Lc4 16.Se3 Lxe2 17.Kxe2 Sd4+ 18.Ke1 The8 19.Ld2 De4 20.Kd1 Dd3 21.Te1 Sb3 0-1 Makarichev,S-Vaganian,R/Tbilisi 1973/MCD (27)) 9...e4 10.Sxd5 Dd6 11.c4 exf3 12.Lf4 Dxf4 13.Sxf4 Lb4+ 14.Kf1 O-O 15.Lxf3 Txf4 16.Lxc6 bxc6 17.c5 1-0 Makarichev,S-Huebner,R/Amsterdam 1975/MCL (45))
9.Se3 O-O
(Also possible:
9...b6 10.O-O Lb7 11.b3 O-O-O 12.Lb2 ---> 1-0 Kundin,A-Rabinovich,A/Israel 2002/CBM 088/[Kundin] (39))
10.O-O Dg6
(Worse is: 10...Sb6 11.Sg4 Dg6 12.Sh4 (12.Sfe5 Lxe5 13.Sxe5 Sxe5 14.dxe5 Ld7 15.b3 c5 Kapengut-Yurtaev Kiev 1978) (12.h3! e5?! 13.Sgxe5! Lxe5 14.dxe5 Lxh3 15.Sh4! De4 16.f4 Ld7 17.Ld3 Dolmatov,S-Yurtaev,L USSR 1978 1/2-1/2 ??!) 12...De8 13.Sf3 e5 14.Sgxe5 Sxe5 15.Sxe5 Lxe5 16.dxe5 Dxe5 17.c3 Lf5 18.Le3 Sc4 19.Ld4 Dd6 20.b4 b6 21.Te1 Tfe8 22.Lxc4 Txe1+ 23.Dxe1 dxc4 24.De3 ---> 1-0 Malaniuk,V-Sahovic,D/Lvov 1984/MCL/[ChessBase] (49))
11.c4 Sf6 12.c5 Lf4 13.Sc2

(13.g3 Se4 14.Sg2 Lxc1 15.Txc1 Ld7 1/2-1/2 Marciano,D-Grabert,R/Budapest 1991/EXT 99 (40))
13...Se4

(13...Lxc1 14.Txc1 Se4 15.Ld3 e5 16.Sxe5 Sxe5 17.dxe5)
14.Lxf4
(14.Ld3 e5! 15.dxe5 (15.Lxf4 exf4 16.Te1 Lh3 17.Lf1 Tae8) (15.Sxe5 Sxe5 16.dxe5 Lxe5) 15...Lg4! (15...Lxe5 16.Lxe4 dxe4 17.Sxe5 Sxe5 18.Dd5+ Sf7 19.Lf4))

14...Txf4 15.Sce1
(15.Ld3 doesn't promise anything special:
15...Ld7 16.Sd2 Txf2! 17.Txf2 Sxf2 18.Lxg6 Sxd1)
15...Sg5 16.g3
(Comes to consideration:
16.Sxg5!? Dxg5 17.Sf3 Dg6 (17...Df6 18.g3) 18.Dd2)
16...Sxf3+ 17.Sxf3 Ld7 18.Ld3
(18.b4!? White's idea is very simple- to drive away the knight from c6 , thus, to occupy the e5 stronghold.
18...a6 (18...Sxb4?? 19.Se5) (18...Txf3 19.Lxf3 Df6 20.Lg2 Sxd4 (20...Dxd4 21.b5 Dxd1 22.Tfxd1 Se7 23.Tab1) 21.a4) 19.a4 e5 20.Sxe5 (20.dxe5 Sxb4) 20...Sxe5 21.dxe5)
18...Dg4 19.Le2
(Another interesting attempt to get an edge is
19.Se5!? Sxe5 (19...Dxd1 20.Tfxd1 Txd4 21.Sxc6 Txd3 (21...Lxc6 22.Lxh7+ Kxh7 23.Txd4) 22.Txd3 Lxc6 23.Te1) 20.dxe5 Dxd1 21.Tfxd1 Tf7 /=. But, it is clear, that white's advantage (if there is any) is very small...)
19...Dg6 20.Ld3
(20.b4! -see 18.b4)
20...Dg4 21.Le2]
8.O-O Ld6 9.Te1

[22...h4 Schwarz steht etwas besser,haette also auch weiterspielen koennen. Aber trotz moeglicher Verwicklungen ( s.24..Sg4!? in der folgenden Variante) waere ein Remisergebnis wohl am wahrscheinlichsten gewesen.Ausserdem: Der Spatz in der Hand.....!
