Zukertort, Johannes Hermann – Steinitz, William
1st World Championship
1.d4 d5 2.c4 c6 3.e3 Bf5?! 4.Nc3
A slight inaccuracy. Analysts suggest that 4.cxd5! cxd5 5.Qb3, hitting d5 and b7, 5…Bc8 favours White.
4…e6 5.Nf3 Nd7 6.a3?!
With the idea of c5 and b4, thereby keeping Black’s dark square bishop away from h2-b8 diagonal.
Euwe gives 6…Ngf6 7.Bd3 Bxd3 8.Qxd3 Qb6!.
A somewhat dubious move as it allows Black to play very energetically with the e5 lever. This is otherwise not possible because of cxd5 which wins pawn for white.It is good to play 7.Bd3 Bxd3 8.Qxd3 Ngf6 9.e4 which seems equal to me.
Trying expand on the queenside, but now the development of White’s dark square bishop is an issue.
9. dxe5 Nxe5 10.Nd4 has been recommended by analysts.
9…Ngf6 10.Bb2 e4!
In my opinion a very strong move. Although it is not directly winning it does shut White’s bishop out almost permanently.
11.Nd2 h5! 12.h3
12.b5?! would be an interesting idea.
Regrouping his pieces. This kind of move is affordable when the center is closed and you have a space advantage.
Trying to expand on the queenside.
All Black pieces are eyeing the kingside.
14.b5?! Nh4 15.g3
Zukertort might have thought that the knight must retreat, but here steinitz came with creative idea of sacrificing knight for two pawns and an attack.
15…Ng2+! 16.Kf1 Nxe3+ 17.fxe3 Bxg3 18.Kg2 Bc7 19.Qg1?
A much better continuation would be to play 19.a5 Rh6 20.Nf1 a6 21.bxc6 bxc6 22.Kf2 when the position is very unclear. Now it’s time to bring another piece into the attack with a threat of Rg6.
19…Rh6 20.Kf1 Rg6
Black has a very powerful attack now.
The only safe square left for the queen.
Now there is no way that White can protect the h3 pawn.
If white tries to defend with 22.h4 then 22…Bh3+ 23.Ke1 Bg3 pins and wins the queen.
Forced in order to protect the g3 square.
23…Bxh3+ 24.Ke1 Ng4 25.Bxg4
25.Qh4 would lost on the spot because of 25…Nxe3 26.Rxg6 fxg6 27.Qg5 Ng2+ 28.Kd1 Qf7.
25…Bxg4 26.Ne2 Qe7 27.Nf4 Rh6
27…Rf6 was a much better alternative when 28.Qg2 Bxf4 29.exf4 e3 is winning for Black.
28.Bc3 g5 29.Ne2 Rf6 30.Qg2 Rf3 31.Nf1
31.Nxf3 just loses a piece.
Black’s last piece joins the attack via the b file.
Trying to find some shelter.
A mistake that gives White chance to eliminate the Bishop on g4 with 33.Nh2 Rh3 34.Nxg4 hxg4. But White misses his chance…
A gross Blunder
33…f4 34.Rh1 Qf7 35.Re1 fxe3+ 36.Nxe3 Rf2 37.Qxf2
There is nothing much that white can do, eg 37.Rhf1 Rxg2 38.Rxf7 Rxe2+ 39.Rxe2 Kxf7 is winning too for Black.
38.Rhf1 Rb2+ 39.Bxb2 Bxa5+ 40.Bc3 Bxc3+ 41.Kxc3 Qxe3+ is also winning.
38…Bf4+ 39.Kc2 hxg4 40.Bd2 e3
40…Bxd2 41.Ref1 Qxe2 is a draw now as white has perpetual checks, tThough 41…Qxf1 42.Rxf1 Bxa5 is winning.
41.Bc1 Qg2 42.Kc3 Kd7 43.Rh7+ Ke6 44.Rh6+ Kf5 45.Bxe3 Bxe3 46.Rf1+ Bf4
