Mondiale di scacchi: quinta patta (combattuta) su cinque partite
Un'altra difesa siciliana con la variante Rossolimo e un'altra patta, la quinta su cinque partite del Mondiale di scacchi di Londra tra Magnus Carlsen e Fabiano Caruana. La novità però, almeno per questo match, è che lo sfidante italostatunitense coi pezzi bianchi stavolta alla quarta mossa non scambia il proprio alfiere delle caselle chiare col cavallo avversario ma opta per la mossa più giocata in quella posizione, e cioè l'arrocco corto sul lato di re. La partita è quantomeno molto più movimentata (ma bastava molto meno...) della quarta giocata martedì, col Bianco che a un certo punto ha due pedoni di vantaggio, oltretutto dopo averne dato in pasto uno all'avversario alla sesta mossa (attacco Gurgenidze), e il campione in carica col Nero verso la fine ne ha uno ma la patta per i motori scacchistici è evidente fin dalla 18a-20a mossa. Entrambi sbrogliano ogni situazione giocando sempre le mosse giuste e gli scacchi a raffica di Caruana al re nero, entrato abbondantemente nella metà campo avversaria (quando il materiale è poco sua maestà diventa un pezzo molto forte!), non preoccupano minimamente Carlsen, dopo l’ultimo dei quali, col pedone g bianco, viene sancita l’ennesima patta alla 34a mossa quando i due giocatori hanno quasi tutto il materiale sul lato della scacchiera dei rispettivi monarchi: re, torre, alfiere delle caselle scure e tre pedoni per ciascuno. Oggi la sesta partita in cui Carlsen avrà il Bianco così come nella settima, i due ragazzi prodigio si inventeranno qualcosa di clamoroso? Qui di seguito lo svolgimento della quinta partita: se siete sulla home page di questo blog dovete aprire l’intero post per vedere tutte le mosse e tutti i commenti scritti dal 19enne Grande Maestro norvegese Aryan Tari per ChessBase.

Please, wait...
1.e4Not surprisingly, Caruana sticks to his usual first move.c5Again a
Sicilian by Carlsen, which is logical considering the fact that Black was
doing quite OK in the previous games.2.Nf3Nc63.Bb53.d4cxd44.Nxd4
I would be very interested in which variation Carlsen would chose here, and I
hope we will see this in one of the upcoming games.3...g64.0-0!?
White diviates from games 1 and 3, where he played Bxc6. This logical move is
also very popular, and played many times on the top level.Bg75.Re1e5
As in the earlier games, Magnus likes to put his pawn on e5 as early as
possible, not allowing e4-e5.6.b4!?Played instantly by Caruana and
clearly his preperation. This move made me happy to watch, as it looks sharp
and interesting. The most dangrous scenario for Carlsen would now to be
unprepared for this move. But actually he had faced it before!6.c3
is how White usually continues when they don't take on c6.6...Nxb4
Played after only a few minutes thought, which means that Carlsen was probably
ready for this line.6...cxb4is what Carlsen answered as a young kid many
years ago, and the move which seems most logical. The game followed:7.a3Nge77...b3Played recently by Grischuk with success against Bacrot in
rapid. The point is just to sacrifice the pawn back and keep the a-file closed,
and then to just develop.8.cxb3Nge79.Bb20-010.d410.b40-1 (48)
Bacrot,E (2708)-Grischuk,A (2761) Paris 2017d5!NAnd Black is first
to strike in the center with a good game.10...d5with a complicated battle
8.axb40-09.Bxc6bxc610.Bb2d611.d4f612.Nbd2Where Black was
quite passive and the White posistion looks very nice. ½-½ (52) Stellwagen,D
(2524)-Carlsen,M (2553) Wijk aan Zee 2005 CBM 105 [Finkel,A]7.Bb2Simply
developing the bishop to a good square and threatening a pawn. Other moves do
not make much sense.7.c3Nc68.d4exd49.cxd4Nxd4!7...a6
Again played quite fast, probably meaning that Carlsen was just spending some
time remembering his analyses.7...Qc7is also a move to consider, just
protecting the pawn.8.c3Nc69.d4d6I would be curious to see what
Caruana had planned here, but it looks easier to play White as he has the
attacking chances.9...Nf610.dxc5 looks nice for White10.d5a611.Na3Ke7∞With an unclear and very sharp game. I believe that
White has compensation for a pawn at least, but if he is better or not remains
a question. Black went on to win a fighting game in 0-1 (44) Rapport,R (2676)
-Granda Zuniga,J (2665) Camarinas 20138.a3The only challenging move,
still in Caruana's preperation.8.Bf1?Just does not make sense, and
afterNc6White cannot play Bxc6 and Black remains a pawn up.8...axb5
Played after 5 minutes of thought, and I believe it was still in his
preperation. This leads to some simplifications, which is usually beneficial
for the defending side:8...Nc69.Bxc6dxc610.Nxe5Nf611.Nf3 Was also a possibility, but I would chose White as he has the better
structure here.9.axb4Rxa110.Bxa1d6Defending the important e5 pawn.10...cxb411.Bxe5!Does not look so healthy for BlackBxe512.Nxe5Ne713.Qe211.bxc5Ne7Finally Black gets time to develop his
knight and is preparing to get the king to safety. White must try to create
something fast, as if Black gets one more developing move he has a perfectly
fine posistion with the bishop pair.12.Qe2Forcing the play. Still blitzed
out by Caruana and his prep, although it does not lead to much:12.cxd6Qxd613.d4Looked very logical to me, opening up the game before Black has
castled.exd414.Bxd414.e5Qb415.Nxd415.Qxd4Qxd416.Nxd4b4
Black will castle next and have nothing to worry about.15...0-0 Black has activity and a nice posistion14...0-015.Bxg7Qxd116.Rxd1Kxg7A critical posistion. The question remains if
White can create something against Black's doubled pawns in this ending, but
probably Black is too active.17.Na317.Nd4b418.Nd2Rd817...b418.Nc4Nc6=12...b4The only move which saves the pawn.12...0-0?13.Qxb5±Would just lose a pawn.13.Qc4Renewing the threat and
stopping Black from castling.13.c3Nc614.cxb4dxc515.bxc5Qa516.Nc3Qxc513.Qb5+Nc6 and Black should be OK as
he gets to castle next!13...Qa5! Forcing the
queens off:13...Nc614.d4!Seems dangrous for Black:exd415.Nxd4Bxd415...Nxd416.Bxd4would lead to collapse of the Black posistion0-017.Bxg7Kxg718.Rd1± and White wins a pawn.16.Bxd4Be616...0-0?17.cxd6Qxd618.Bc5+-loses the exchange.17.Qb50-018.Be3White has a risk-free advantage.14.cxd614.Bb2?Be614...Be614...Nc615.d4!Qxa116.d5 Looks
only fun for White15.Qc715.Qe2Qxa116.dxe7Qa6! Black
is doing great15...Qxc716.dxc7Nc6=Protecting the important e5-pawn
before planning to eat the pawn on c7 with Kd7. I guess that probably around
here the notes of the players ended, and they are on their own. We have
reached a position where White has a healthier structure, but at the same time
Black has the bishop pair and some activity - I would say enough counterplay
for being OK. Still White needs to spend some tempi to bring the b1-knight to
life. Black should be happy about the outcome of the opening!17.c3
Prepares to bring the b1-knight into the game.17.Rd1 What I
was expecting. Simply preparing to open up with d2-d4.Kd718.d4b3!
A surprising move, but it solves the problems mainly because of the activity:18...exd419.Nxd4Nxd420.Bxd4Bxd421.Rxd4+Kxc722.Rxb4Kc6and the
question is if Black has enough compensation for the pawn, but it is clear
that White is in the driver's seat at least:23.Nc3Ra824.Kf1And
Black is the one who has to play precisely in order to make a draw.19.Nxe5+19.dxe5+Kxc720.cxb3Bxb3Black is too active and
has a nice b-pawn. I would definetly take Black in this posistion.19.cxb3Bxb319...Kxc7!19...Nxe520.dxe5+Kxc721.cxb3Bxb322.Rc1+20.cxb3Ra821.Nd221.Nc3Bxb3!21...Bxe522.dxe5Ra2Although Black is two pawns down, he has
enough compensation: Extremely active and good king, and the b3 pawn should
fall at some point. The White pieces are rather stuck.17...Kd717...b3?18.d4+- is a killer!18.cxb4Ra8Annoying move. Although
he could take on c7, it makes more sense to get the rook to a better square
first.19.Bc319.Nc3?Nxb4!19.Bb2Ra2!19...Kxc7Black
remains a pawn down, but still White did not solve the b1-knight problem, and
Black has a much better king + bishop pair. Carlsen definetly has an easier
posisiton here20.d3Gets a new square for the b1-knight.20.Ng5
Actually the only move that reaches equality. But quite desperate and not so
logical..Bc421.Nxh7Obviously an ice-cold way for a human to play...20.Rc1Kd720...Kb6?!20...b5!
The only chance Carlsen had in the game to be better. The b4-pawn is weak, and
this just seems as a more comfortable posistion to play for Black. At least
Caruana would have to be precise here. Usually Carlsen is always taking these
small chances when he gets them, so I'm a bit curious what he missed. As the
game continued, there was not much happening.21.Kf121.Bd2Rd8!22.Nc3Rxd323.Nxb5+Kb624.Nc3Nd4maybe the line Carlsen
missed?21...Ra422.Bd2Nxb421.Bd2!Preparing Nc3, and kind of
profylactic against Kb5.21.Ng5Kb522.Nxe6fxe623.Kf1Bf8!21...Rd821...Kb5?!22.Nc3+Kxb423.Rc123.Na4+!22.Be3+Kb522...Kc723.b5!23.Nc3+White finally gets to develop his knight and
the posistion gets simplified:Kxb424.Nd5+!Basically a draw is forced.Bxd524...Kb325.Rb1+25.exd5Rxd526.Rb1+Kc327.Rxb7Nd8!28.Rc7+Kxd3 Black is a pawn up, but White is too active and
the d8 knight is stuck to protect f7. One of the pawns will be lost.29.Kf1h529...e4??30.Ne1#Would be a funny mate!30.h3Ke431.Ng5+Kf532.Nxf7=Nxf733.Rxf7+Bf634.g4+Black offered a draw as there is nothing to play
for with 3 against 3 pawns on same side.½–½
