FM Chuck Schulien - Ray Lietz BBS Game 1992
Two Knight's Defense, Max Lange attack
1 E2-E4 E7-E5
2 G1-F3 B8-C6
3 F1-C4 F8-C5
4 O-O
This method of development is certainly not the most incisive;
better is 4.c3 or 4.b4!? ( Evans Gambit). The following pawn
sac is dubious, but gave me good results when I was playing
the king pawn openings 15 years ago.
Today the line 4.d3 is popular, leading to quiet positions in
the opening.
G8-F6
5 D2-D4 E5-D4 X Pawn
While it is certainly sound to capture this way, play leads
to the Max Lange Attack, where White stands no worse. The
attempt to refute White's play begins 5...Bxd4 6.Nxd4 Nxd4.
White doesn't get the quick line opening and tactical chances
which he craves with the gambit.
6 E4-E5 D7-D5
7 E5-F6 X Knight D5-C4 X Bishop
8 F1-E1 C8-E6
9 F3-G5 D8-D5
10 B1-C3 D5-F5
11 C3-E4 O-O-O
12 G2-G4 F5-E5
13 G5-E6 X Bishop F7-E6 X Knight
14 C1-G5
This move is less analyzed than the old 14.fxg7 Rhg8 15.Bh6,
which leads to equality after 15...d3 16.c3 Be7 17.Qf3 Qd5
18.Qf7 Bh4 19.Rad1 Ne5 20.Qf4 Ng6 21.Qf7 Ne5, or 17.f4 Qd5
18.Qd2 Rd7 19.Re3 Nd8. Finally, the line 16...d2!? 17.Re2 Rd3
18.Qf1 Qd5 19.Rd1 Ne5 20.Nf6 Qf3 21.Nxg8 Qxg4+ is a perpetual.
14 G7-G6
This is doubtless the best response; 14...Rd7?, 14...Bb4?, and
14...h6?! are worse.
15 F6-F7 C5-E7
16 F2-F4 E5-G7
17 G5-E7 X Bishop C6-E7 X Bishop
18 E4-G5

Here Keres suggested 18...d3!? 19.Nxe6 Qxf7 20.Nxd8 Rxd8,
sacrificing the exchange to eliminate the passed pawn and assume
the initiative. In my opinion, Black has sufficient play in
this line, but it is no better than the text.
18 D8-D6
19 E1-E6 X Pawn D6-D7?
Surely correct is 19...Rxe6 20.Nxe6 Qxf7, ridding himself of
the thorn at f7. There follows 21.Qxd4 Re8 22.Ng5 Nc6!, with
excellent play for Black. White may try 22.Re1 Nc6 23.Qxc4,
answering 23...Nd8 with 24.f5 ( forced! ) but it is not an
easy game: White's king is in jeopardy.
20 D1-E1 G7-F8
21 E1-B4 D4-D3!
This diversion prevents White from quickly doubling rooks on
the e-file, which would end the game.
22 C2-D3 X Pawn
22.Qxc4 d2? 23.Rd1 h6 24.Nf3 Qxf7 25.Ne5 wins for White, but
22...dxc2 23.Qxc2 h6 24.Ne4 Qxf7 25.Nc5 is no improvement, so
White plays the simplest way.
22 C4-D3 X Pawn
23 A1-D1 H7-H6
24 G5-E4 F8-F7 X Pawn
The amazing 24...Nc6?! is well met by 25.Re8+ Rd8 26.Rxf8 Nxb4
27.Rxh8 Rxh8 28.Nc5 Rf8 29.Re1! Kd8 30.Ne6+, and White should
win the ending.
25 E4-C5 C7-C6
26 B4-E4
The attempt to simplify to a won ending with 26.Nxd7 Qxe6
27.Qxb7+ leads to more complications after 27...Kxb7 28.Nc5+
Kc7 ( also possible is 28...Kb6 ) 29.Nxe6+ Kd6 30.Nd4 c5, when
White must brave 31.Nb5+ Kc6 32.Nxa7+ or allow ...c4 with
an inferior position.
26 D7-C7
27 C5-D3 X Pawn H6-H5
28 D1-E1 H8-H7
29 G4-G5 C8-B8
30 D3-C5 E7-C8
31 E6-G6 X Pawn
White has a tremendous bind on the position, and certainly
could have played 31.b3, preventing queenside counterplay by
Black. Then 31...Rg7 32.Qe5 and Re8 present themselves as ways
to strengthen his game.
Nonetheless, White's plan is quite sufficient to win, but
requires a bit of accuracy along the way.
31 F7-A2 X Pawn
32 C5-E6 H7-E7
33 E4-E5 A2-D5
34 E5-D5 X Queen C6-D5 X Queen
35 F4-F5 E7-E8
36 F5-F6 C8-D6
37 E6-C7 X Rook?
But this is terrible! White has an easy win beginning 37.Rg7!,
when the passed f pawn glides to the eighth rank. In the game,
Black gains tremendous counterplay based on the passed d pawn
and White's loose pieces.
37 E8-E1 X Rook
38 G1-F2 E1-E5
39 G6-G7 D5-D4
The knight ending 39...Rxg5?! 40.Rxg5 Ne4+ 41.Ke3 Nxg5 42.Kf4
must favor White. Similiarly, 39...Ne4+ 40.Kf3 Nxg5+ 41.Kf4
and 40...Rxg5 41.Nd5 are poor choices.
If the game continuation turns out to be losing, then Black
may wish to search for hidden chances in these variations.

White goes wrong in this critical position, missing a
defensive resource.
42.Kg2 prevents a rook check on f5, allowing White much better
possibilities of queening the f pawn. We examine four
responses: 42...Kc8, 42...Nxg5, 42...d2, and 42...Nc5.
A) 42...Kc8 43.Rxd3 ( also 43.Rd5 Rxd5 44.Nxd5 wins ) Kxc7

B) 42...Nxg5 43.Re7 ( 43.hg5 Rxg5 44.Kh3 Kc8 is OK for Black )

still win ) Rf5 45.Ne6+-

White failed to take this check into account when examining
his fortysecond move. The king cannot quickly assist the
passed pawns, and Black has the advantage, if not a clear win.
45 F3-E3 B8-C7 X Knight
46 B2-B4 C5-D7
47 E3-E4 F5-F1
48 D2-D5??
This blunder is symptomatic of a lack of attention by White,
who fails to appreciate both his resources, and the value of
calculating checks and captures!
White still resists with 48.Kd5!, when Black cannot easily
improve his position without allowing White some sort of
counterplay. For example,
48...Kd8 49.Ke6 ( 49.Kd6 is possible ) Ke8! 50.Rc7! Nf8+
51.Kd6 unclear
48...Rf4 49.Ke6 Re4+ 50.Kf5 ( 50.Kf7 deserves a look as well )
Rxb4 51.g6? Rb5+ 52.Ke6 Rb6+ -+, 51.f7! Rb5+ 52.Kg6 is good
for White.
48...Nf8 ( critical ) 49.Ke5 Ng6+ ( he can wait for a move
with ...a6, but this doesn't significantly affect the position
) 50.Ke6 Nxh4 51.Kf7 Rg1 52.Rd5, 51...Nf3 52.Rd5, and White
still has chances.
48...Nxf6 49.gf6 Rxf6 =+ This isn't a simple win, if won at
all.
