Am Besten wir nehmen keine geringere Referenzpartie als die einzige Siegpartie des aktuellen Weltmeisters aus seiner diesjährigen Titelverteidigung.



Hier mußte Anand seine Chance ergreifen die unklare Stellung im Königsangriff zu entscheiden.

Er tat dies mit 10.Dd2 und späterem g2-g4.

Der kommentierende Meisterspieler regte sogar sofortiges 10.g2-g4 !? an.

Der freie Komodo 3 tut sich hier noch etwas schwer die Chancen für den Angriff zu sehen und braucht 1 h 48 Min. auf einem Q6600 mit 2,4Ghz.

1. d4 Nf6 2. c4 g6 3. f3 c5 $5 {Gelfand deviates from 3...d5, as he played in
game two. It is very interesting to play ...c5 right now, since in a normal
Saemish System in the Kings Indian, White would be on time to play Nge2
(against ...c5) in order to delay the d5-push. See the line below.} (3... Bg7
4. e4 d6 5. Nc3 O-O 6. Be3 c5 7. Nge2 $5 {is one of the main lines in the
Saemish.}) 4. d5 d6 5. e4 Bg7 6. Ne2 O-O 7. Nec3 $5 {An absolutely normal move.
In that kind of positions, White usually has problems developing his two
knights healthily. Usually, the b-knight is already on c3, and the other one
goes to g3 in order to free the bishop on f1. Then Black goes ...h5, ...h4
very fast and in general White is not in time to castle in order to play
Nh1-Nf2 (which is a "dream" square for the knight). The move played by Anand
solves all those problems, and is clearly the good reaction against the 3...c5
line.} Nh5 {One of the moves suggested by the engine. Though a bit weird,
since Gelfand played very fast, I cannot decently critize that move, though I
would like to. I guess one of the ideas would be to go ...e5, and suddenly the
knight would be very well placed on h5 (if ...e5 without ...Nh5, I guess White
could go g4!, while with the knight on h5, Black wants to counter g4 by ...
Nf4!). The move played by Anand seems like the most natural.} (7... e6 {would
be more natural.}) 8. Bg5 $5 Bf6 ({The engine suggests} 8... h6 {but White
would just go} 9. Be3 {after White Houdini proposes} g5 (9... e5 $6 10. Qd2 {
is already different: White will go Na3, 0-0-0 and Black will lose time due to
the h6-pawn which is misplaced. If Black needs ...Kh7 later, it will be very
difficult to play ...f5, since White is going to put a bishop on d3.}) 10. Nd2
Nd7 {but White just goes} 11. Qc2 {followed by 0-0-0, and on the long run I
simply don't believe Black's position can be good.}) 9. Bxf6 exf6 {Definitely
the logical move after going ...Bf6: but according to the engine, Black's
position is worse already.} 10. Qd2 (10. g4 $5 {seems quite strong:} Ng7 (10...
Nf4 $2 11. Qd2 Qb6 12. Na3 g5 13. h4 $16) 11. Qd2 Nd7 (11... f5 $6 12. gxf5
gxf5 $2 13. Qh6 $1 $16) 12. Qh6 Qb6 13. b3 {followed by Be2, and either h4-h5,
or simply 0-0 with a positionnal advantage.}) 10... f5 11. exf5 Bxf5 12. g4
Re8+ ({The natural} 12... Bxb1 13. Rxb1 Ng7 {is not enough to equalize after}
14. h4 $1 h5 (14... Nd7 15. h5 $40) 15. Kd1 $1 {(typical maneuver)} Nd7 16. Kc2
a6 17. Be2 b5 18. Rbg1 {and I believe White's attack is quicker.}) 13. Kd1 Bxb1
14. Rxb1 Qf6 $4 {A terrible blunder, though the position is already worse.} ({
After} 14... Nf6 15. Kc2 {White will have a fast attack on the kingside, while
Black is very slow in finding counterplay (after ...Na6 White will either go
a3, or remove the rook from b1 to leave b1 free for the white king!).}) 15.
gxh5 $1 Qxf3+ 16. Kc2 Qxh1 17. Qf2 $1 {It seems Gelfand just missed that move!
As against Topalov, Anand managed to equalize the score right after losing for
the first time! Very impressive. However, it seems quite clear Gelfand somehow
couldn't handle the pressure of becoming a "favourite" in the match. Let's not
forget Anand played several World Championship matches, while Gelfand is
playing one for the first time, and had an absolutely amazing course to reach
it.} (17. Qf2 Nc6 $8 18. dxc6 Qxc6 19. Bd3 $18) 1-0

Hallo Thomas,
Komodo 5 64-bit findet den Zug g4 auch nach einer halben Stunde nicht bei mir.
Außer Stockfish haben alle Engines, die ich getestet habe, den Zug gefunden.
Angefügt ein paar Beispiele.
Gruß Wolfgang

Hallo Wolfgang,

es handelt sich schon um eine sehr gezielt ausgesuchte Stellung , die eine spezielle Schwäche der jeweiligen Programmreihe kurz anleuchten soll. So eine Art kleiner Prüfung ob der Programmierer an dieser  Schwäche bei seinem Programm gearbeitet hat.

Damit kann ich immer schön checken ob die neue Version grundsätzlich auch mehr vom Schach versteht als seine Vorgängerversionen und nicht nur hauptsächlich an der Suche gearbeitet wurde.

Mit den Jahren entwickelt man halt so seine bescheidenen Tricks.

Gruß und Dank

Thomas
