morning all I like to show you an absolutely classic encounter when
Fischer was just 16 in the bled Zagreb Belgrade's candidates tournament in1959 he
was playing against Tigran Petrosian. Tigran Petrosian was a soviet armenian
grandmaster world champion between 1963 and 69 he was nicknamed iron tiger
pardon me .. iron Tigran ... due to his almost impenetrable playing style which
emphasized safety above all else he was a candidate for the World Chess Championship
on eight occasions 1953 56:59 62 71 74 77
1980. He won the World Championship in 1963 against Mikhail
Botvinnik and successfully defended it in 1966 against Boris Spassky and lost
it in 1969 to Spassky thus he was the defending world champion or a World
Championship candidate in ten consecutive three year cycles. He won the
the Soviet championship four times nineteen fifty-nine sixty one sixty nine
and seventy five and is recognized as the hardest player to beat in the
history of chess. I would like to add on this channel there was a set of videos
Kasparov against Petrosyan which I called conquering a style but it should
be noted that in the latter two encounters Petrosian's health was
suffering which may have had a big impact on those games. In the early
encounters against Kasparov it was shown that Petrosian was a great wriggler
especially with his king being able to wriggle his King into safety. Let's look
at this game then - so Fischer with White kicked off with e4 and Petrosian played
the caro-kann - a very solid opening but maybe a bit of a surprise - perhaps
Sicilian was expected we see Nc3 and Petrosian played d5 and now this
variation Nf3 - okay so this is the two Knights variation not very
originally named - both knights coming out called the two Knights variation - Bishop
g4 pinning a knight and black is emphasizing a dark square strategy
actually this signifies to undermine white on the dark squares by taking on
f3 at some point potentially and we'll see this -White encourages black to do
that exchange getting a light square bishop now Nf6 d3 e6 and this
Bishop it could go to e2 but actually g3 is favored and this move is very
popular Bishop b4 which aims to actually exchange off the dark square Bishops and
leave white even more vulnerable potentially on future dark squares and
you'll note in particular c3 - keep a note in particular of the c3 square so a
strategic Bishop exchange here - Black is now threatening d4 so not giving white
time to play Bishop g2 either - that would be a pretty bad Bishop g2 here d4 even
though a3 black has Queen a5 here and is unclear to lose the exchange like
this so okay so this is this is very theoretical Bishop b4 even today this is
the most popular move and Bishop d2 now is played and black does go in for the
bishop exchange with d4 driving the knight back to b1 but it can come back
out potentially to use the c4 square on this exchange and Petrosian did actually
take immediately on d2. I think nowadays this is quite a rare idea to take
immediately on d2 because it seems to be helping White get the knight to c4.
Queen b6 has been played at least eight times according to my (Chessbase) "live book" Bishop
takes d2 much rarer. Petrosian played it anyway accelerating this
Knight coming back to c4 which seems a very comfortable
idea and in fact it seems strange maybe that Petrosian not only encourages
this Knight to come to c4, is also saying to white you know do it to attack e5
giving e5 a target but the point of e5 is to lock in this Bishop this fianchettoed
Bishop so ok Bishop g2 - no rush to play Nc4 c5 giving black the c6 square
potentially for the knight. Castles now knight c6 Queen e2 getting out of the
way of the F pawn so this is a typical Kings Indian in reverse and a Kings
Indian attack formation where f4 now and you might think the pressure on e5 might be
good in conjunction with Nc4 later. Petrosian plays Queen e7 and we do see this
kind of Kings Indian attack formation and black now castles Queen side. I think
castling kingside looks a little bit riskier perhaps white can just play f5
potentially unless it's really weakening the dark squares considerably but it
looks like a standard thing you do in the Kings Indian defense to roll these
pawns up so castling Queenside maybe seems a bit safer in some respects
and Fischer gets to work now on on the Queenside but it's not just about the
King - this next move which he plays a3 - it's about potentially undermining with
e5 the e5 if Nc4 is happening then b5 would also be a very
useful threat to undermine this e5 pawn and break black's structure in fact
also beat bxc to try and undermine black's pawn structure here. We see now
Knight e8 which does mean black is possibly playing f6 soon to
maintain that pawn chain which is like a lock and key against this Bishop and
possibly in this position you might consider F takes e5 but it's not that
effectual in this position F takes e5 Knight takes e5 say b4. Black
has a very impressive knight on e5 here and this attack really needs this Bishop
but it's completely blockaded so this might not be ideal in in this position
to play F takes e5 not only that for example let's take this a bit further
black might even be able to play h5 to try and weaken White further on the dark
squares so this kind of position doesn't seem too bad for black but it's a
possibility that needs to be factored in to play F takes e5. Fischer actually
played b4 and now here again what happens if f6. Well maybe b5 this might be
okay for white to use this kind of plan and the bishop might not be too terrible
with h4 Bishop h3 later so this might not be that bad it's a bit blocked in
but in the game Tigran undermines his own structure here in the center with
the move C takes b4 a bit provocative in some respects and here now F takes e5 is
under slightly better circumstances than earlier much earlier because the knight
and queen are now ready for b4 here also the Knight is kind of protecting a7
so this is a very different position here much more effective in fact it
seems for f takes e5 to be reconsidered whilst before positionally it could be ruled out
- here this looks like it's quite attractive if Knight takes e5
that's particularly bad - a takes and we are on a7 so slight nuances that means F takes e5
is more effective here and this pawn chain being
undermined with no c5 pawn makes queen f2 more effective and all of a sudden we've
got resources like c3 targeting a7 so in this position after C takes b4 it does
seem that F takes e5 is a viable idea here - if black takes the Queen
maybe check and rook takes f7 this is this is nice for white so okay but
Fischer in the game played Knight c4 and this gives to Tigran a chance to maintain
his pawn chain with f6 and in some way really justifying blacks C takes b4
actually because now the pawn chain has been maintained black has actually
weakened this c3 square with the earlier strategic exchange of dark square Bishops
the c3 square is a great target for a positional maneuver like this and also
black has the potential here to create an outside passed pawn already there were
the seeds of an outside passed pawn in a position to be born more in mind this
Bishop is still locked in and this pawn chain ok against the knight c4 seems
solid enough now white plays F takes black takes with F pawn a takes and now
b5 is a serious threat in this position very very serious threat but Nc7 has dual
purpose not just against b5 but the Knight can consider coming in later to
c3 which has been weakened white is weak on the dark squares here. Knight a5 and
now Tigran does a very very good move potentially white is threatening Knight
takes and rook takes a7. Does he use his King ?! If he uses his King to protect b8 this
might be playable takes because how does White actually gain more pressure
here let's give an example Knight b5 is pretty solid supporting a7 it looks as
though black shouldn't have too much of a problem here. White is playing without
this bishop in this position this diagonal is not really something to be
scared about so this is not too great for white this
kind of position so King b8 does seem playable but Tigran played
actually Nb5 which is also playable immediately setting sights on c3 white
plays Knight takes c6 bxc6 which can protect that pawn doubly now with
Knight and the Queen - so what can White do?! he's with this kind of dead bishop has
he got that much play against black?! his next move rook f2 as though he's
interested in doubling on the F file -we see g6 potentially getting out of the
way if if there's a doubling on the f-file g6 and now we see h4 king b7
and now Fischer plays h5 so he's trying to get some something going on
the kingside here. He's got that f-file. Kind of gazing down the f-file. Now if
immediate Nc3 this pawn is also been on here in principle it seems as a bit
dangerous to leave f7 Queen takes b4 is actually played check King b6 it looks
strange for the King to be on b6 as well but if the King did step back then I
think that might be much more dangerous Queen f2 and we've got resources like c4
in fact because of this - this is an important idea in this position if black
takes a7 is gonna be under fire so okay and now we see Queen f2 and it looks as
though c4 now is possible using that pin on the d4 pawn. That's the principle
kind of threat and Tigran could have tried to dampen that down by
playing Queen b2 here - okay the white rook moves and now a five and
now c4 and we can just take on f2 and then play Knight c3 but he didn't nail
down c4 here in fact after Queen f2 Tigran played a five allowing c4 which
sorts out one connectivity issue that now White's pieces can can swing to
the Queen side potentially but this is a very strong Knight now on c3 protecting
key squares the King - it looks as though the King is strange on b6 but this is
Tigran Petrosian he's very good with King Safety - one of the most difficult
players to beat ever in the history of the game and he knows how to put his King
into great safety so it seems paradoxical to walk it up the
board but in this situation now he's got this very nicely entrenched Knight
he's got this running past outside pawn and he's controlling key squares well
enough for King safety not to be such a major issue
rook f1 which might be a slight mistake perhaps Queen f6 as pointed out by my
analytical assistant here with Queen g7 potentially and there is a threat of Qxe5 - what would black do?!
maybe rook d f8 and we can have hairy continuations like this but white should
be okay but in the game we see this move rook f1 and now black can really
emphasize that passed pawn. a4 is played Fischer plays Queen f6 trying to
counter-attack on this side of the board and probing touching both rooks with
this move means that now rook takes h7 to deflect one rook away from protecting
the other is on the cards. That's kind of ignored now - perhaps best for black would
have been Queen d6 after Queen d6 it seems it's a difficult position for
white here it seems for example Queen g7 it doesn't matter about such checks here
because the King remarkably can use the c5 square here and White's attack is
running out of steam and again we're faced with this menacing passed 'a' pawn in
this position so okay so Petrosian played actually queen c5 which i think
is is a little bit less accurate than Queen d6 and now it allows Fischer's
next move rook takes h7 getting a pawn okay
but now look Rdf8 queen takes rook takes h7 does Petrosian want to exchange off
rooks - well in principle yes he's got this outside dangerous past pawn but
White has also got now this dangerous 'h' pawn to counterbalance this 'a' pawn
so yes Petrosian takes on f1 though and pushes his 'a' pawn and the white queen is
a bit helpless against this pawn queening. All White can do now is try and
queen himself how can he get back in time?! There's no way so we're in a
strange situation here where the earlier dark square strategy led to white being
weak on the dark squares and this wonderfully entrenched knight on c3
maintained king safety for kings on opposite sides of the board which has
now culminated in two passed pawns on opposite sides of the board so white
plays now h6 and black plays a2 and they're both going to queen quite ruthlessly
Queen g8 setting the queening square - a1 queening -
h7 and black believe it or not hasn't got really time to exploit White's King
safety here although it seems the shot Ne2 check might be promising what
would go on here?! Say King g2 there is a shot here Knight takes g3 so that if
King takes this is crushing Queen takes f1 that is a big big problem here
imagine this scenario Queen takes d3 this is not very nice for white at all
Black's got the checks in first here and is left with material advantage but
Knight takes g3 - you might think well Queen takes again there's Queen f8 so
this is an important tactic to consider because it's putting a dampener on
things it seems but in this position white can actually force a perpetual
check With check check check check and
there's no escaping it because if if this loses the a7 square because here
if we try and win this queen there is queen a7 and this is just perpetual check again
so the king cannot escape the perpetual checks here so perpetual checking saves
the day in this position but it was an important tactic to bear in mind this
Knight e2 check for Knight takes g3. Petrosian actually played Queen d6 and now
we have the four Queens on the board which makes the game very unique to have
four Queens. It's very rare this happens in very high-level games so I think the
preconditions for it to happen were : both sides castled opposite to
each other, black had the signs of an outside passed pawn earlier on and white
was working on the Kingside to generate a dangerous passed pawn himself
and we have this remarkable scenario now so what is white actually threatening if
he had another move. Well he'd start checks maybe which would be pretty dangerous
maybe he wouldn't mind exchanging off a queen and to try and pick up e5 and
then use his 'g' pawn later. Well Petrosian guards against Queen b8 Fischer in
this position plays the move g4 which is actually apparently one of the best
moves to play from an engine perspective in this very very complicated position
if he tries Queen e8 this seems to be a viable alternative to just target the e5
pawn black might be able to respond Queen a to e7
it's strange to have to qualify Queens but it's a wonderful aspect of this four
Queen scenario and say Queen a8 very complicated
position indeed really this kind of scenario very unusual Queen dc-7 is example
White has always got the option as well to try and trade off one pair of Queens
this looks good for white from at least from an engine point of view this this
position so Queen e8 looks like an alternative to g4 which is what Fischer
played - rather optimistic I guess to try and think of that pawn as now queening
in this new scenario Petrosian does something very
interesting he continues his King walk with the move king c5 now okay and now
we see white playing Queen f8 exchanging off one of the Queen's potentially.
Queen a to e7
but now avoiding the Queen exchange I don't think this is good for white here
taking Queen h6 this might not be that's hot for white
here because black has these invasion points in this position like f3 in
particular so what Fischer did here is actually
Queen a8 - he is bearing in mind the check possibilities and Petrosian does the
only move I think Queen a3 looks like a very very serious threat
especially with c5 coming up potentially as a resource so he plays actually King
b4 - the King helps himself to defending here the a3 square and we see
now Queen h2 is though there's an interesting queen b2 and remarkably again and
this is why I think Petrosian is an amazing King wriggler and with this King
wriggling he even had later success against the likes of Kasparov in some
games the King helps himself to defence with King b3 remarkably but
it does also mean now that Queen a3 is possible with this battery of Queens
as well - so we see Queen a1 and the Knight is covering key squares here b1
and d1 as well. Black now plays Queen a3 and if white refuses an exchange of Queens
now let's say white plays Queen e1 then Queen g5 it looks very difficult indeed
to see what White's actually doing here so Fischer simplifies now the position so
alas that's the end of the four Queens now after Queen takes a3 King takes
a3 Queen h6 and then we see Queen f7 interested in that f3 square and the
King defends f3 with King g2 and now we see the move King b3 - where is
this King heading?! Well it seems that's potentially there's Nd1 to e3 on the
cards so the King is stepping out of potential checks like on d6 perhaps - was
this really a threat for white or Queen c1 check in particular is more relevant
so the King is stepping out of checks here. Fischer goes back with his Queen
and we see now Queen h7 which looks a little bit odd what does the Queen
actually doing there?! It's standing by this pawn it doesn't look as
though it's got major prospects and now a bit of a howler from Fischer - he plays
King g3 which allows a nice tactic. I wonder if you can spot it if I give you
10 seconds starting from now ...
okay Queen takes e4 there's a nice fork here if takes Knight takes e4 check and
black is winning here in this position so ..
Fischer plays the much better queen f2 which keeps his chances alive and after
queen h1 .. Fischer offered a draw which thankfully for him was accepted. He
was a bit nervous about it not being accepted black is slightly better black
has got prospects of e4 here but Petrosian I guess was extremely tired after
this game with the complexity of the Four Queens earlier decided to .. well a
draw was accepted so let's see in this final position if Queen g2 Queen h6
Black's better but it's not so clear about e4 as long as e4 is stopped
black has some work to do
but okay it's it's still very very complicated. The win is going to be
a protracted struggle from this position so fair enough
after Queen h1 a draw was agreed so an intense and exciting game with four
Queens on the board - an extremely memorable game indeed comments or
questions on YouTube thanks very much.
