A Brief History

About the Cwo-Kam In General

The ~~ &fen= was in t rpdud into seri~us cam- @tion by &e German players H, C m and M. ? b n in the last * of tkte ninetenth century, As Om Might expect far an opening whose fmt ~ ~ p l e was solidity, initially it was not gn&d with great enthusiasm from the majority of chess fans, Nw&dess, its intrinsic merits stwn cattght the at&ti.~n of some of tkle worid's leading masters and it has k n championed by many tap players throughout the last huxmdred yews. No less a player than ~ l ; u z r r a . USHI it ta g d e f f e on several -ions, biting some aF ESle mast eminent grandnaasters of his m with his c u s t a w virkuosity. A classic example, featurr?d in WE h k , is his game against Nmowhch p h y d in the New Yak s u p e t a u m e n t of 1927. A few years lam Soviet GMs btvin- nik and FIohr tnak over; their scientific treatment of the game doing much to enhance

the opening's popularity. Since then, the Cam-Kann

has t e n ow of the main weap- o m in most World Champions' oping mw, BOtYhik, smysrov, Petroslan, Karpov 4, ocrrixsionalb, Kasparov have sucmssfully d e f d the Bf& side, especially in matches at the highest level. 1 suspect this choice was not at d by chance, as the "Caro" is easier ta play than the SiCiEm, the SpantSh or even the French, espddly if Bid is sttisfid with a dmw. HowwwI the asynm&mX pawn s t r u a which arises & e r t e 4 c f t 2 d 4 d 5 3 & 3 dxe4 means that B k k mn dm play for a win, on the andition that he will w q t a slightly worse position by avoiding Uquidatium during the early phases of the g m e .

Advance Variation The Advance Variation I3 e 3 is the most mhml way ta side step Black's bm tende*s and was seriously test& for the Frst time in ttre World CXmampianship match betwen Tal and Botvinnik in 1961. Tds

resuit with it was mther dis- appointing (as was his wb1e pfomxance~ and this was p b b i y responsible for the line's abndonment in the next twenty years. TRe line was revivect in the g m Hart- Sehwan, Bad Kissingctn 1981, which, however, resulted in a M l h t win for Black. Whilst a m might have expected this t a b v e d t h e r w i v d to b stillborn, in f& the opposite was the case a d it soon be came apparent that Black muld not hold his awn in the h a k raisirtg mrnpli~tsons after 3 ... QfS 4 e6 ?6 g4!? Q& 6 Qge2 cS 7 h4 cxd4?! 8 Qxd4 hS 9 f4!. Later an, B1adr & v i d ways of improving his play by M a t @ on the 7th move and by now the attention of White p1ayers has switched to more positional (and safer) ptths.

Over the past M e , the abve mentioned system (start- ing with 4 Q.3 & S g4!?) wns mainly championed by the Dutch GM and twice Ciurdi- dates' finalist Jan Xmman. He contributed a tat ta i t s dwe lapmmt with. many interesting

novelties, but in mast of the games he failed to reap the fruits of his I h w sin= same positions are easier to play with Black, even if he stands abjwt- ive1y worse! This might swm a bit discouraging ta the average player, but one should not forget that the primay purpose of chess analysis should be ta h d our wedmesses rather than impmve our s ~ ~ .

My pemd e x p & ~ n e with the variation, espeddly the alternative 4 ... w, taught me that one should not trust msults but ody objective d y s i s . I started playing the Advaxlm in 1%; at the time n d d y w d d m p t that 5 NJ!? mutd I d to some sort of game for: White. T d y , 1 think that the move is worthy of an !? and tamarrow - who h w s ? - the evaluation might change again. On the strength of the analysis presented in &s book, it is my F m &lief that 4 &3 is at lleas q u d ta the alternatives and I hope that readers will add their awn contribution to the history of this topid w i n g .

I Ideas in the Advance Variation

The Caw, has long been con- sided one of Bids main defences against l &. World Champins -lam, Botvin- I& anc3 Karpov have been its reguxar p ~ t i o w s , which s p k s itself far the soundness of the system and its partimlar merits: solidity, clarity a d mntroued aggmsion. Contrsuy ta the typicrnl Frrnch Defence scc?nario, the l ight - squd bishop ~ I I develop f ~ l y dong the c&hJ dagod arzd the stniggle is of an open nature with dear-at aims.

The Advance Variation is c k m c k k d by the move 3 e& partly closing the centre. In h t sense it is not a typical Caro-Kann and might ~ s e discomfort to players whose main athadion to the opening was its simplicity, Also, Black is denid the M t i o n a l count- mphy along tfre d- and Ips- sibIy1 g-files as well as tke quam f6 for his knight's de- velapmt.

In c o ~ s o n with the French Advance, Black has ~~ the pciYi1ege of d e veloplng his bishop on fS. How-

ww, this dws not automatie ally rn that he has also managed ta solve alf fris o p - ing problem: he is a tempo duwn in tke fight for the center with the break ... S and the bishop's pasition might tun out ta Ix vulnerable. Ttte pur- pose of this d o n is not tr> give con^ evaluatkons re- gadhg these questions, but to examine typical situations with a view to helping readers in th& aswsmenrs.

3lm; Centre Tke situation in the centre is dways a major factor, defining the c k w & r of the chess struggle. In our case, the Nm- zowitsch' pawn structure Id4, e?s for White, &, d5 far Bl& m s that White will have to meet the tt-msts ,,, or ... f7-f6 ta his center and shape xwrdingly his own p h . These Invdve f2-FbfS, hitting the lxw of B i d s pawn chain, as well as expinsion on the kingside with gains of time an the emmy bishap,

Sometimes White exchanges the light-squad bishops in

return far a s p e and time advantage. Illen his pmpelr readion ta 3 l d s e n d thwh differs; it has ta do mom with piwe ~ c x ? u M i n g rather than pawn stmms.

&EDIF going on, it should be nutd that the main object of this hmk is tn d y s e posi- tions where White develops his queen's knight on c3. Although Wte is deprived of the pos- sibifjty c Z 4 , fortifyjng hjs rxntre, he d v e s a lot of compensation in the form of quick development and eml- lent attazhg chces. Sho~'~ way of treating the

psition @3 and Qe2, al- though by far the most solid orre, does not put Black under pn3sm right from the start, Therefore, kt itis a useful wqmn only for those who wish to avoid complications at an early stage. Zt is outside the spirit of this bwk ta suggest such a he, s k it does nut comp1y with the g e n d dbxtiuns of ht t ing the C a m - K m as they have a t d y been d e d M abve.

In this part of the h k , I wish to take a clase look at various general situations White may encounter in p c ti-. Here I have taken some h i e s with the diagram irl order to add more emphis to pawn structures and their ~ f a r m a t i o ~ s .

In our fa diagram, Black

has chosen to attack the base of White's chain by ... o&-cS. It seem that tMs thrust is more effdve here than In the k n c h , as the bishop stands &ively an g6 while r n t e ' s mntm U s the pruktive c 2 d . However, q w a m l c e s can Ix deptive. White does not n e s d y have ta I-&- force $4 with a pwn; a knight would .$ very strong t k . Ln addition, Black has spent two h p i to get his pawn ta 5 andits -one6 jacks the valuable protection a Id' bishop muid provide. Not surprisingly, this invites Wfiib to attack with D-f4-fS.

kgmn 2 shows the results

of a correct White strategy: the E~pawn has ackevd the shut- ting in (wen krn@yI OF the b k k Mshop, while putting 6 urt$er d o u s pressure. TIre pressure can b in& by moves Eke @-f4 or QFt-h3, as captures on f5 weaken deci- sively the dS pawn, B l d s only c k n m is to strive for oountef play on the queenside by means of ... &c4, ... b7-tx5 etc. (see atso the d o n 'Flank Activity').

It. goes without saying that an mriy ... cSxa4 favours Whib since his p i e s b r n e active and the thematic p i w n a d m e R-f&-fS gains in staength.

Now we shall pmmd to examine pasitions where Black challenges White's central supaiority with .., fl-f6. Such a pasition cafl lx seen in &stgram 3.

3 l d s choice has a two-fold purpose: to create a moMe pawn-mass in the ten* and simultaneously provide a safe spot for his bishop an 0. Wrn that square the bishop also e the newly-cmwl

weakness an e6, albeit at some cast in mobility.

A typimf stauckm often arising in practice is the one pmsent*?d in diagrsun 4,

Black has achievd his aim of obtaining a pawn m n d e r - mce in the centre as White touk back on eS with the d- pwn. This is, however, kt* than f4xe5 which deprives W h ' s pition of its dyna- rnism and leaves thf? epm p d d l y isolatd, .,, &c5 not

far away. White should now huwy ta deploy his h g h t ta fJ via d4, preventing the psitiod threat ... g7-g5. If he faib to stap it, 3 1 d s bishop will h out for g d after tfre f o d V t U T e &kg6 e.p

Sametimes Black delays taking on eS, thinkmg that he has all t k h e in the wurld at his disposal. This is a risky strategy and White can take advantage of it by a timely capture an f6.

So far we have only lmkd at positions with Ught-squad W s h p s on the Ex*- ing these bishops seems anti- positiond far W h h , but it can 't>e justified if Black weakens his kingside or neg1wt.s Iris development. After all, Whikts remaining b i s k is not that bad' if one mmpres its pres- ent mobility to its b M m n - terpart. What white players should 'be aware OF, is the p- tentid danger of drifting into a passive ending, especially if the position in the wntre s t a b ilks.

Diagraan 7 features such an ending, with W f i t ~ having the inferior bishop and a pc?rmanent wedmess on d4. W s kind of endgame might I32 b d f e , but it is &vious1y not in am's

The new situation without light-sq- bishops de- mds a slightly different approach but bas id ly the principle is tire same: open up the pasition when you have the chance! This m s that White should avoid amwering ... with c2-r.3, as that wwId lead ta a fixed e n t d structure, identical to the one in the previraus diagmn.

A typical reaction to ... c6-d after the exchange of the light-squad bishops mn be swn in the following diagram:

Flanfr Activity S m is, undoubtdy, the most daubl-edged element in the game of chess. M i k e tempi or materid, rules cannot be made about its fpiative value and waythng depends upon the pMng of the pieces. Thew f o ~ , the players' AiIity to evaluate each specific situation is of p m n w n t importarm.

Regarding the Advance Caro, them is an i m p o r k t axiom mlat.d to the value of space: the side with more? s w in the wnW ean o m t e an either flank with g r e a ~ ease. This axiom is mnfmed r e m y in this variatjon, as most flank attacks are Xatinched by White

White's kingside expansion is a standard method of flank activity m d chamckrkes m y lines af the variation as a whole. It is ground& on the f& that B I d s Wshap on fS provides wte with enough tempi far i t s ndz.atian, aam$ has the two-fold purpose of restricting the bishop's mobility as well as inducing weaknesses in the opponent's pawn fma- tian.

nitely in White's favour, as is demanstra& in Game 5, Nagek Woutms and the extensive d y d s indud& therein,

Zn the above example, White had to mly solely on tactics to avoid falling into aat inferior position. The disadvantage of Bl&s idea was that he wn-

the square d4 ta the white knight with loss of tc?mpo, thus relaxing the en- trai pressure and creating a strong b s e fur White's opera- tiom. Black may deny White using this square by a timely ... c!c4, espsdly when b t h sides cipst1.e lox. Then, relax- ing the mntd ~IVSSW is more justifid as the resuJ.thg pawn ph&m points mertacing- Iy at the white M. h diagmn 13 Black is r d y

Since releasing the h7 bishop adds yet another weapon to Black's m ~ u r y , White must 't>e a w e that investing a piece would r ' a k be necessary if he wants to stave off the mating thats, As is custornaty fur such m s , play b m e s highly u n b d d ; nwtrtheless the pawn on fi' might pmve an i m m t long-term asset Ifw a &aiId analysis see the m n r l match g m e X m m - %wan, EEime 10).

If the light-squad bkhops have k n exchanw, White obviously lacks a target for an analogous expansion on the Icingside. Hawww, the bishops' absence allows White to out a di f f e~nt plan with a view ta gaining SF on the other wing. Take for instarm the -of dmgmm 14:

Here the conditions m idel for Wte ta achieve his aims. Black has spent too much time aeathg a stsongpaint on f5, thus m g l d n g the m & i - tion of his qumside. W h h

mn take advantage of this by playing ,..

as Black is unable during this s q u e m to react suwss- fully by ... M.

finally, an e x q t i a d case, with White attacking an the queenside and at1 pieces still on b a d can IE f m d in the following example:

Black n d s just one t e m p ta c o ~ l ~ ~ E d a t e his centmi psi- tion by playing ... & 7 d . White must prevent this, so tfre energetic i b4! is d i d for, ~ ~ 8 c i n g a pawn ta open lines against the emmy king. f i s move has also the additional

&antage of b d n g up Back's centra3 pawn fmnt, consquently !k&ng d4 for use by WhWfxi pies . All in dl, a promising attack is in sight, requiring only a tiny matwid investment on Whi~"9 ptpart, So far, so good: attacking

ideas have formulated the main part of our discussion. ht as E$unzo~tsctz pointed out many years ago, chess is not only atta$r and defence; it is pre- vention d prophylaxis as well, Sometimes, Wte has to b~ d e s t and think atrout stopping Black's counterplay More going an with his own ~b.

A mse where flank activity has strictly a preventive riile can k s w n in the following de-".

While it is clear tigat White's f u m U e s on the lungside, he gaes in far the pmduxicalf a4. In fact this is not an attadwag gesture, but a solid way ta take tfre sting out af ... &-c5 which w d d now h met strongly by &+bS. Also, White p-epwes

to exchange, if necessary, his inferior bishop by b2-b3, $4- a.

Certainly, Black can dm try to be active on the quwmide. We have d& witness& the case of diagram 13, with Black launching a dangemus attack on the white king; however, in principle queensidle activity bxkFres if there are no con- crete targets and freedom of movement in his interior lines:

I)iagmm 17 features a spa?- gaining effort on the quwnside. Black has just played ... b7-%, W n g he will get away with it, in view of tke closed nature of the parition. But in fact, such reasoning is inmrmX sirtc~? soom or later .+. c6-cs has to m u r axBd B l d s dem- onstration will pmve weaken- ing and timemnsuming.

The reader might have n o t i d that there was MY any mention of White attacks on the kingside without pawns. As a matter of fact, this is a ram bid in tke Advance Varia- tion aamd b going to k e m x a m

k w h g stsongpints for one's minor pieces 1s a common theme in most semi-pen Take For example & Schweningen Variation of the SidQm, where it is a wtaxnaw idea for Black to mate an Outpost for his knight an &, in front of an isolakd white e p w n Coy ... &-&3>64.); ta &we this, he usually con& a correspond- ingly stmng quare Far W h i t on dS, In ow case, t yp id squares for outposts derive From the nature of the central pn formation, and we d4 for Wte md R for B M .

I t is well knawn that in French-Eke pawn stnlctures the square d4 a n b m e a useful base af upratium for White's p i e s . According to Nimwitsch, White should always k q a firm conk01 on d4 and e5 so that when Black: tries ta liquidate his cent& pawns these squares can be taken up by pies , In the French hybrid of the cam Ad-, after 3 ... d?! 4 dxS!, White has emugh time to cmy out these ideas, as ts Black: lost a ternpa without causing any disruption in his opponent's development.

Pachman's last move t&dI-d41 in&=& his p f e m n c e far a better endgame, but also axxptab1e is tfie Nimzowitsr:&an approach, with U-U, nl-e!, to be fullawed by &3-e2-d4. In bath cases, the superiority of knight vs bishop is quite evident.

The knight on d4, apart from i t s bl-ng duties, m sewe attacking purposes as well. we have a h d y witnessd tihe case of diagram 12, where its func- tion was b suppart the ad- vrnrtce of White's f-pawn and simul-sly attack eS, f d - ly resulting In a d c i a t breaktfuu,ugh. Dimlac d e veloprnents are not ta k ex- pxkd in the next example, but the knight's Ale is very shUar.

The main chamctmktic of this pasition is the inclusion of the move ... h7-hb in Mack's defensive set-up. Ttris k s p k s white to attack 4th~ by push-

It should be noted here that, despib the absence of the light-sq- bishops, Whib0s pawn advanes are justifiable as Black m t build the well- known defensive formation with pawns an g6 and hS. As has b d y k n men-

tioned, Black's &tiand out- post, in the enter is the quare 6. Ocnlption of this square by a M g h t presupposes an s l y exchange of the light- q u a d bishops. Black usually strengthens the knight's posi- tion by ... h7-M, a trpical mse shown in dagmn 20:

White is a pawn down, but his knight is ideally piaced on c4, eyeing the weak dark squares an Black's queenside. Black's b- and c-pawns are p d d I y isolated and his epawn herndkbly weak, Although it cannot IE claimed with any cwhinty that White enjoys an advantage here, it is

obvious that the burden of proof lies an B i d s side.

A difficult problem one hits to soiw &ling o v a the kxwd play is the question of ex- changes. The main reasan for this is that tfxe relative value aF each minor piwe is sensitive, in view of the rnrnp1iated and mnstantly transfarming pawn structures. Mastering this subject requires the ddwelap- mmt of one's intuition, togeth- er with knowidge of same typical w s .

Al Ex&- of &ht-Squad H s h w &fming to this exchange has s d y b m e a mutine, but the w f u l reader must have n o t i d the -on Far such an attitude: exchanging one's awn good isiskop is "gainst tfie principles af dassical theory, so i t is of major importance to explain haw this is is& by otha factors.

B E h g e of a Strongly R d Knight %Is is another mrring theme, as Black quite often esdlisfres tris knight on fS in arder to halt Whitds kingside aggression.

CI Other E x ~ g e s Sametimes, Black gives up his d a r k - s g d bishop for a white taught on 13. Like ib distant relative from the Wm- awer, this exchange aims at a weakening of White's pawn s t n l c t w , hoping to exploit it at a later stage. Under smc dmmswms BIaick may sue d, trut in gemid the fo&- d o n of White's centret in conjuctian with the usual time advantage he enjoys in the Ach- Caro, *ws him to expIait the bishop vs knight

Manoeuvres The Caro Advance is an opening variation x w t d for i t s d m - mism and versatility. There is no manoeuvring in the W- tiod sense, as the whole bd is in m almost pma- mt state of flw and in al- most every game we witness a M y - * M y fight &wen the two armies. mus, tg,we are

TIre only lines where play takes a mare or less positional dwactm are those arising after an d y exchange of the fight- q u a d bishps. Tkse psi- tions require a different kind of approach, since the customary pawn a twms would now fail ta impress Black his pasition is sdficientiy solid ta mwt this kind of activity by setting up a sumssfuI blockade an the light squares, If White under- estimates this fact he will soon rmn out of play on the kmgside, as in the classic game Nimzo- wia-ianm, New Yo* 1927:

White's m 1 e s dmonstm- tion has ended up in a complete stratqic disaster, Black has not only o o n q ~ the s q m

This mmoeum s g d s the start of Black's diffrcut~m, as dm the n o d continuation 1 &2 @? 2 Qg3 he has to make a posi- tional mncession:

The type of game featured in the last few dagmns bears a close3 resemblanm to pasitions from the French. b this m- pet, a knight an e2 might prove wnvenientiy p l d , as it suits white's plan to apply kingsicle p r e s s w with the aid of his mv*. %e queen an h3 proves a usefd &ator OF
