Keene R D - Stein L
Hastings, 1967
1.Nf3 d6 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.0–0 0–0 6.Nc3 e5 7.d3 Nc6 8.Rb1 h6
9.b4 Be6 [par=2]Prepared by Black's last. 10.b5 Ne7 [par=2] 11.Qc2 Qd7
[par=2 ]Preparing the "slide" ...Be6-h3, challenging White's important
bishop. Broadly speaking, White's strategy in the English Opening is to
dominate the central light squares, so the disappearance of his
king-bishop robs his game of most of its punch. 12.Re1 Bh3 [par=2]
13.Bh1 Ng4 [par=3]Freeing the f-pawn. 14.Nd2 Rab8 [par=2]The least
compromising defense of the b-pawn. Note that after 15. Qa4, Black can
riposte with ...e5-e4 (n(either)xe4...f7-f5). 15.Nd5 Nxd5 [par=2]The
only way Black can be rid of the knight d5 (15...c7-c6 16.Nxe7+ and
b5xc6). 16.cxd5 f5 [par=2]Envisioning an opening of the f-line. Note
that an over-hasty ...f5-f4 will cede White's knight the ideal e4
square. 17.Rb4 Rbe8 [par=3 Rf7=2]Quite a deep move. Clearly, doubling on
the f-line is accomplished fastest by ...Rf8-f7 and ...Rb8-f8. The text
move, however, has in mind the possibility of laying siege to the d-pawn
with ...Ng4-f6 and ...Qd7-f7, whereupon pressure on the c-line can be
negated by ...Re8-e7. 18.Nf3 Nf6 [par=3]Tenderizing the d-pawn. 19.e4
White's surest defense of the d-pawn congeals whatever ambitions he may
have had on the light squares. 19...f4 [par=2]Making contact. 19. g3xf4
is, of course, refuted by 19... Qd7-g4+. 20.Bb2 Ng4 [par=2 Rff7=2]The
knight resumes its post with tangible pressure on f2. Of similar intent
is 20...Rf8-f7. 21.Rc4 Re7 [par=2 Rff7=2]Equivalent is ...Rf8-f7.
21...Rc8 is the sort of passive move one makes only when forced. 22.a4
The b-pawn was looking takeable. 22...Ref7 [par=2]Threatening ...f4xg3.
23.Qe2 What? After all I've said about ...Rc8 being terribly passive,
doesn't White force that move by tripling on the c-file? Actually, no.
After 23.Rec1, Black has the following fantastic counter: 23...fxg3
24.hxg3 Rxf3 25.Bxf3 Ne3!! 26.fxe3 Rxf3, when 27.Rxc7 is crushed by
27...Qg4. 23...Qd8 [par=3 h5=2]Planning to infiltrate on the dark
squares. 24.Rc2 h5 [par=2]Preparing to infuse another attacking unit at
g3. 25.Bc1 Bh6 [par=2 g5=1]Affords Black the choice of recapturing at f4
with pieces should the need arise. Further, Black introduces ideas
of...Rf7-g7. Correct is ...g6-g5. 26.Bb2 fxg3 [par=2] 27.hxg3 h4 [par=2]
28.Bc1 hxg3 [par=2]White must respond to the threat of ...g3xf2+.
29.fxg3 Bxc1 [par=2] 30.Rexc1 a6 [par=5]A brilliant move: Black
threatens ...Qb8 and ...Qa7+. 31.Nh2 A defensive measure against...Qb8:
The elimination of Black's knight permits interpositions. 31...Nxh2
[par=3]Conceivably, White will sacrifice his queen in the event of
...Rf2. In the words of the well-known West Coast player, The
Once-Mighty Carl, "What are you doing to yourself? What are you doing to
your poor self!?" 32.Kxh2 Qg5 [par=3]Black rules out any defensive queen
sacs by sighting the rook c1. Meanwhile, the threat seems to be
something to the h-file. 33.Kxh3 Rh7+ [par=2] 34.Kg2 Qh6 [par=2] 0–1

Janowski D - Lasker E
Paris, 1909
1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.Bb5 Bb4 5.0–0 0–0 6.d3 d6 7.Bg5 Bxc3
8.bxc3 Ne7 9.Bc4 Ng6 10.Nh4 Nf4 [Par=2 h6=–1]Rules out any ideas of f4
(White threatens to capture on g6 and advance f2-f4). h6 loses material
after Nxg6. Note that, if White captures the knight f4, he forfeits the
advantage of the bishop-pair. 11.Bxf4 exf4 [Par=1] 12.Nf3 Bg4 [Par=2
c6=1 Be6=1]Black threatened Nxe4 with attack on the knight h4. After
this move, White has difficulties in developing any meaningful
aggression. 13.h3 Bh5 [Par=1]Note White's difficulties at breaking the
pin because of Black's handy f4 unit. 14.Rb1 b6 [Par=2 Rb8=1]In such
situations, commentators frequently suggest defense of such pawns with
pieces, so as not to incur weaknesses. However, here Lasker judges
correctly that a minute weakness in his queen-side is preferable to a
reduction of mobility. 15.Qd2 Bxf3 [Par=2]White's pawn structure
continues to degrade; now boasting three "islands" of pawns with two
lonely atolls on the a and h files. One should jump at inflicting such
bloody pawn wounds. Additionally, how does one defend f4 without these
moves? 16.gxf3 Nh5 [Par=3]Never use pawns to do a man's job: They can't
retreat. 17.Kh2 Qf6 [Par=3]A good positional move securing the Kingside
dark squares. 18.Rg1 Rae8 [Par=2] 19.d4 Kh8 [Par=2]A building move,
stepping out of any possible danger down the g line and freeing the
f-pawn from the pin. 20.Rb5 Qh6 [Par=3]Again, Black employs piece-play
to maintain his position. The permanent, static nature of his structural
advantage affords him that choice. 21.Rbg5 f6 [Par=3]After his many
preparations, Black begins to take over the king-side squares. No credit
for the flashy Ng3, hanging the f4 pawn. 22.R5g4 g6 [Par=2] 23.Bd3 Re7
[Par=2]Again a modest building move. It's impossible to over-emphasize
the positional value of these little moves. Black's plan is simply to
improve his pieces to the maximum. He wants to open the position when
White's doubled pawn pairs will tell and his decentralized rooks will
look silly. 24.c4 Ng7 [Par=4]What's this? Hanging the guy on f4? Of
course. After trades on f4 (not 25.Rxf4 Ne6 winning at least the
exchange), the knight hops to e6, scoops up the d-pawn and Black's
knight reigns. 25.c3 Ne6 [Par=1]The knight is very strong on this
central square. 26.Bf1 f5 [Par=2] 27.R4g2 Rf6 [Par=2] 28.Bd3 g5
[Par=3]With the big threat of Qxh3. 29.Rh1 g4 [Par=4]Black has strong
threats on the king-side and in the center. A capture on this square
will un-prop the e-pawn. Meanwhile, Ng5 is coming. 29... g4 30.fxg4 Ng5
31.Kg1 fxe4–+. 30.Be2 Ng5 [Par=2 gxf3=2]  31.fxg4 f3 [Par=2] 32.Rg3 fxe2
[Par=2] 0–1

Teichmann R - Schlecter K
Karlsbad, 1911
1.e4 Never did Richard Teichmann (1868–1925) play so powerfully as he
did here in this monster event, crushing all his rivals and proving
himself to be one of the strongest players of the day. Karl Schlecter's
turn came in the eighteenth round. Schlecter's drawn match with Emanuel
Lasker the year before had added to his reputation as being the most
difficult man in the world to defeat. Teichmann adopts his pet line, the
seemingly quiet 9.d3 and gains control of the vital d5 and f5 squares.
After this, his attack surges irresistibly. 1...e5 2.Nf3 Nc6 3.Bb5 a6
4.Ba4 Nf6 5.0–0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0–0 9.d3 Na5 10.Bc2 [par=2]An
essential move. In the Ruy Lopez, the squares d5 and f5 are
strategically vital. Without his white-squared bishop, White cannot hope
to control them. It may be said that, at c2, the cleric waits in ambush.
He may reemerge at b3. Or, after some clearing of the center, he might
pressure the black king-side. 10...c5 11.Nbd2 [par=2 a4=1]One of the
Ruy's virtues is that in most variations it denies Black freeing
exchanges. If it permits exchanges, it derives some form of
compensation. However, the Ruy demands accuracy, in that White must
deploy his pieces thoughtfully and meaningfully to effective posts. At
this moment squares don't exactly cry-out to White's pieces; his queen
bishop, for instance. Hence the text move, which is virtually reflexive
for Ruyites. 11...Qc7 Black shores up e5 in readiness for a freeing d5
push. 12.Nf1 [par=2 a4=1]Also reasonable is a2-a4, probing the Black
queen-side. 12...Nc6 13.Ne3 [par=2 Bg5=1]Prevention (d6-d5) and
aggression (possible hops into f5). Bc1–g5 also prevents d5, but might
lead to unwanted exchanges after Nf6-e8. 13...Bb7 Almost an invitation.
14.Nf5 [par=2] 14...Rfe8 15.Bg5 [par=3]An important move, after which d5
is answerable with the guard- removing Bxf6. 15...Nd7 16.Bb3 [par=2]Back
to this attacking diagonal now that the bishop cannot be molested.
16...Nf8 17.Bd5 [par=2]This threat to capture on c6 and e7 in turn pins
Black down. 17...Ng6 18.Bxe7 [par=3] 18...Ngxe7 19.Bxf7+ [par=2]Other
continuations promise little; Black threatens to exchange-off the
attackers. 19...Kxf7 20.Ng5+ [par=2]This is the only logical
continuation of the attack. 20...Kg8 Why is this move forced? Black's
possible retreats refuted by Ne6, Nxg7, or Nxf7. 21.Qh5 [par=2
Qb3=–1]Qb3+ is defeated by... c5-c4. 21...Nxf5 22.Qxh7+ [par=1] 22...Kf8
23.Qxf5+ [par=1 exf5=1] 23...Kg8 24.Qg6 [par=2]Black hoped to
play...g7-g6 to bring his queen to the defense. 24...Qd7 25.Re3
[par=2]The clincher, coming in to seal off the f-file. 1–0

Flohr - Ravinsky
Moscow, 1944
1.d4 Salo Flohr (1908–1983) emigrated to the Soviet Union from
Czechoslovakia during the Second World War. There the notorious
drawing-master for some time succeeded in sharpening his style, as in
this game against a minor Soviet master. 1...d5 2.c4 c6 3.Nf3 Nf6 4.Nc3
dxc4 5.e3 b5 6.a4 b4 7.Na2 e6 8.Bxc4 Nbd7 9.0–0 [par=2 Qe2=2
b3=1]Prudently castling before commencing operations in the center.
9...Bb7 10.Qe2 [par=2]White threatens e3-e4. 10...c5 11.Rd1 [par=2]A
normal move, but awkward for Black to meet. His queen is likely to be
exposed on both of the natural squares c7 and b6. Note that White
threatens e3-e4, ...N(or)Bxe4, d4-d5 with attack. 11...Qc7 12.Ba6 [par=2
e4=2]The text is a deep positional move, cutting Black's b-pawn off from
his comrades. White intends dxc5 and Bd2, harvesting the little guy.
12...Bd5 13.Bd2 [par=2]Threatening dxc5. 13...Rb8 14.Rdc1 [par=3
Rac1=1]The a-rook performs valuable sentry duty over the a-file. Black's
queen again must move. 14...Qb6 15.Bb5 [par=2]Gunning for the b-pawn.
15...a5 The only way to firmly guard the b-pawn. 16.Ne5 [par=3]Virtually
sentencing Black's king to live out his days in the center. 16...Bd6
17.dxc5 [par=2]White continues to confuse Black's pieces. 17...Bxc5
18.e4 [par=3]Black can scarcely capture this pawn in view of his pinned
knight. 18...Bxe4 (...Nxe4 19.Nxd7, wins) 19.Bg5, threatening to take on
f6 and d7 in turn. 18...Bb7 19.Bg5 [par=2 Nc4=2]Because it will reduce
Black's mobility yet more, White plays this move anyway, as a purely
positional move. Also good is 19.Nc4, winning a pawn next move with
Nxa5. Probably, White's pressure is worth at least a pawn. 19...Bc8
20.Bf4 [par=3 Rd1=–1]Not recommended is 20. Rd1, allowing 20...Bxf2+ 21.
Qxf2 Qxf2+ 22.Kxf2 Nxe4+, and ...Nxg5. 20...Ra8 21.Qc2 [par=3
Rc4=2]White's position continues to improve while Black's game
regresses. Also good is Rc4, with the idea of doubling. 21...Be7
22.Qxc8+ [par=3]In view of Black's cramped state almost mundane.
22...Rxc8 23.Rxc8+ [par=1] 23...Bd8 24.Nc4 [par=2 Rad1=2 Nxd7=3]Better
than the text move is the immediately winning 24.Nxd7 Nxd7 25.Bc7,
winning back the queen when White has an extra piece, or gaining a
bucket-load of material. 24...Qd4 25.Be3 [par=2 Re5=2]Getting the idea.
Note that ...Qxe4 puts the family in a fork. 25...Qd3 A perilous square.
A takes nerve to leave one's queen under discovered attack. 26.Bc5
[par=2 Na5=2]Setting up 27.Nd6+. Also good is 26.Nxa5. 26...Nxe4 Hoping
to emerge materially okay, after say, 27.Nd6+ Nxd6 28.Bxd3 Nxc8. 27.Ne5
[par=2]The idea is 28.Bxd7+ and 29. Rxd8. 27...Qxb5 28.axb5 [par=1]
28...Nxe5 29.Rd1 [par=2 Bb6=1]Also good is Bb6, allowing ...Kd7,
whereupon Black can crawl into an endgame. 29...Nd7 30.Bb6 [par=1]
30...Ke7 31.Bxa5 [par=1] 31...Nxf2 32.Rxd8 [par=2 Bxd8=2 Kxf2=1 Bb4=2]
32...Nxd1 33.Rxh8 [par=1] 33...b3 34.Nc1 [par=2]Black shouldn't be
allowed to keep his b-pawn. 34...Nc5 35. Bb4, ruthlessly. 1–0
