Kasparov explained move by move

Kasparov-Ponomariov 2002

White to play (Diagram I)

Garry plays 1 a4! This opens a second front, making the defensive task harder for Black.

If Pono tries to defend his pawn by 1..c4 then 2 Qb6! Re7 3 g5! and White's victory is near.

Therefore, Pono plays 1..e4 2 ab5 ab5 3 Bb5 Qe5 reaching Diagram II

White to play ( Diagram II)

Here Kasparov plays 4 Qg5!

If 4..Be6 then 5Bc4! is decisive. The bishop cannot be taken in view of 6 Rd7+. and 5..Re8 6 R1d5 Qf6 7 Qf4! leaves White winning.

If 4..Ra7 5 R1d5 Qf6 6 Qh6! similar to the game,

The game went 4..Qe7 5 Qh6 Be6 ( because 5..Qf8? loses against 6 Bc4+ and 7 Rd8+).

We reach the next position :

White to play and win (after 5..Be6) Diagram III

Here Garry clinched the victory by playing (after repeating the moves) 6gf5!

After 6..Bf5 7 Bc4+! Ke8 8 Qf4! is strong, so Pono played 6..gf5

The game ended : 7Be2!

A great move bringing the bishop into the attack via the h5-e8 diagonal.

7..Qf6 8 Bh5+ Ke7 9 Rxe6! 1-0

Final Position

Position after 9 Rxe6! 1-0

9..Qe6 10 Qg7+ wins

9..Ke6 10 Rd6+! wins

Carlsen-Kramnik Blindfold Brilliancy (10)

Another brilliant game at Amber, this time Vladimir Kramnik produced a blindfold masterpiece !

[Event "Amber Blind"]
[Site "Nice"]
[Date "2009.03.25"]
[Round "10"]
[White "Carlsen,M"]
[Black "Kramnik,V"]
[Result "0-1"]
[ECO "E32"]
[Opening "Nimzo-Indian"]

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 O-O 5. e4 d6 6. Bd3 Nc6 7. Ne2 Ba5 8.O-O Bb6 9. d5? Nb4 10. Qd2 exd5 11. cxd5?! Ng4! 12. Bb1 Qh4 13. Qf4 f5! 14. exf5Bxf5 15. h3 Bxf2+ 16. Kh1 Bd7 17. Qg5 Bc5! 18. Rxf8+ Rxf8 19. Ng1 Rf1! 20.Bxh7+ Kh8 0-1

After 13..f5!


Comments :

5 e4 !? is a interesting attempt to deviate from main lines of 4 Qc2

7..Ba5!? Kramnik relocating the bishop to b6 to attack d4

7 Nf3 instead of 7 Nge2 has the advantage of controlling h4, which was a factor in the game

8 a3!? to prevent Nb4 and prepare b4, without castling was probably an improvement on the game 8 0-0.

9 d5? more cautious was 9 Be3 Ng4 10 h3 Ne3 11fe3 Qg5 12 Rf3



11 Nd5 was probably better than the game's 11 cd5.

12 Bb1 sounds passive but 12 h3? Ne5 13 Bb1 Bxh3! with idea Nf3+

14 ef5?, it was better to admit that Black's attack is dangerous and play 14 Qg3

15 Bf5 was not possible because of 15..Rf5! 16 Qg3 as 16 Qf5 is met by Qh2 #.

Instead of 20 Bh7+, 20 Nce2 Bg1 21 Ng1 Rg1+! 22 Kg1 Qe1 is Checkmate

20 Bh7+ was a cheap trick, as 20..Kh7?? is met by Qxh4+, but Kramnik correctly played Kh8 of course.

I Black to play and win (warm-up level)

1..? Leko found a neat way to end the game immediately with a tactical shot against Kamsky (Tal Memorial 2008).















The chinese player Wang Hue rated 2704, has been on a roll. After finishing first at the Sochi Grand Prix (tied with Carlsen), he won the strong dutch tournament NH in Amsterdam.

II-White to play ( Wang Hue-Adgestein , NH Tournament 2008) Level Difficult


1.? How do you break Black's defense ?

Tactical Motif VI : Attacking the King

Roughly 50% of all combinations are centered around attacking the king. Besides topical checkmates( Smothered,Boden,etc), there are numerous themes involving the king hunt.
Here we present examples where the bishop pair is instrumental in the attack.

King attack: Illustration

15.? White to play and win ( Lasker-Bauer 1889)
















This famous combination by Lasker , with a now thematic double bishop sacrifices,started with:

15.Bxh7+! Kxh7 16.Qxh5+ Kg8 17.Bxg7! ( Second bishop sacrifice, opening the king) Kxg7 18.Qg4+! Kh7 19.Rf3 e5 (only defense against Rh3) 20.Rh3+ Qh6 21.Rxh6+ Kxh6 22.Qd7! 1-0
