Morra Gambit in practice

The Morra gambit (from the player from my hometown Nice,France Pierre Morra who studied and played it) is still a dangerous weapon against the Sicilian.

White to play for the initiative (23rd move)

Ivanchuk-Kramnik 2009 ,Tal Memorial Round 9

The 2009 Tal memorial just finished, with Kramnik taking first place. Congratulations to Vlad for a victory in a super strong tournament ! His style was energetic throughout the whole tournament.

1-Kramnik 6/9
2&3 Ivanchuk,Carlsen 5.5/9
4&5 Anand,Aronian 5/9

Anand was in contention for first place but lost his last game to Aronian pretty badly.

It looks like Ivanchuk had a very strong attack against Kramnik in the 9th round, but he missed the critical continuation somewhere between move 21 and 25.
Concrete analysis and full game on the following 2 links:

Post tournament, there is a lot of chatter about Carlsen being unofficially the best rated player in the world ( less than a point ahead of Topalov!). This is following lots of hype about Kasparov training Carlsen to become the next world champ.


My simple and subjective view on the top chess players currently is as follows:

1.Anand and 2.Kramnik are the two strongest players as of November 2009. I believe that if they were to play another match, Kramnik would try to play more dynamically, which is he what he did in his next tournaments. I noticed that Anand had not won a tournament since he is world champ, but played well enough to finish 2nd ( or here 4th). These two players are stronger than the field at this juncture.

Next come 3.Topalov,4.Carlsen and 5.Aronian. These 3 are achieving impressive results with regularity at the very top, but wouldn't at this stage challenge succesfully Anand or Kramnik in a match.
What about the 2010 Topalov-Anand match ? I believe Anand would be clear favorite if the location would be in a neutral country. Having it in Sofia,Bulgaria is definitely increasing Topalov's chances, as Anand may feel psychologically presssured to play in Topalov's home country with obvious and numerous benefits.

After these 5 players, there is another layer of still super strong grandmasters. The main difference would be their consistency (or lackthereof) or experience at the very top.
This would include Ivanchuk,Morozevich,Gashimov,Vachier-Lagrave and Nakamura among many others. Ivanchuk for instance may very well win the Tal Memorial or Wijk aan Zee, as he is a truly brilliant player. He may just not sustain this level throughout the year.
These players are sometimes less well-known, which is why tournaments like London 2009 are exciting as new players are given a chance to compete against the best.
Nakamura will compete in London 2009, and Vachier-Lagrave won Biel 2009 ahead of Morozevich and others.

White should capitalize on having all his pieces developed.

Quick attacking repertoire against the Pirc

A little introduction to the Austrian attack against the Pirc. Even though this blog is primarily focused on tactics, the following opening primer is geared at creating tactical and sharp positions from White's perspective.
It also gives supporting material to the tactical puzzle Nakamura-Smirin presented in an earlier post ( look for tag Nakamura to see previous Naka puzzles !)
http://www.top10chess.com/2008/05/tactical-quiz-easy-medium-level.html

1 e4 d6 2 d4 Nf6 3 Nc3 g6 4 f4 Bg7 5 Nf3



A) Black can simply castle here 5..0-0
6 e5 Nfd7 7 h4 !?
Start of the attack.



7..c5 8 h5 cd4 9 hg6 dc3 10 gf7+ Rf7 11 Bc4
This is the tabiya (key position) in this variation.


Here Black can play 11..Nf8 or 11..e6. Current theory suggests the latter is better.
The Nakamura-Smirin Foxwoods 2005 game featured 11..Nf8 with a spectacular win for White ( 22 moves !).

B)

5..c5 Black delays castle to react in the center

6 Bb5+



After 6..Bd7 7 Bd7+ Black can recapture in two different ways

B1)7.. Nbd7 8 d5 0-0 9 0-0 Ne8 10 Kh1

White has attacking prospects with f4-f5. See Le Quang-Gurevich 2008 for more.

B2)7.. Nfd7 8 d5 Na6 9 Qe2 0-0 10 0-0


White has a pleasant position. See Shirov-Hulak 1992 for more.



NOTE:
In Variation B ( 5..c5 6 Bb5+ Bd7 ), I chose 7 Bd7+ but the main theoretical move is 7 e5. Here's an important game for this continuation ( 18 f5 and 20 f6 are typical of this variation ):

In each position below, the goal is to find the best continuation.
Tactics and missed calculations in action...

Position I: What did White play here ?

1. Qxg5 or 1. Rg1

Position II: Black to play , earlier in the same game

Black played 1..Qb6. Does Rybka agree?

Position III: Black to play
I just played Qe4-e5 in the position below, to control b2 and play h5-h6.
Enough to win ?

I was playing White in all three positions:
I was able to win in position I, while I shouldn't have survived the game if my opponent had seen the right move in position II earlier on.
I won with White in the last diagram, but only after my opponent let me back in the game.

Sicilian Scheveningen Tabyia

The position below, White to move, appears after the following move :

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3a6 6. Be2 e6 7. a4 Nc6 8. Be3 Be7 9. O-O O-O 10. f4 Qc7 11. Kh1 Re8



Now, a standard way to play this position with White is develop along this scheme:
Bf3,Qd2,Nb3 and then g4-g5.

Intead, an interesting idea is to play 12 Bd3 !? leading to the following position.



The idea is to target the black king directly through d3-h7, with e4-e5 in mind. Usually Black plays Nb4-d3 to eliminate the White bishop but that is not always enough to equalize.

See a good attacking game below by Jakovenko

Tactical motifs and kibitzers

The following position appeared with Black to play

Black played 1..Qh4 !?

After this startling move from Black, how would play the position with White ?

a) Yuri, the russian expert, said " Russians always go forward. Therefore 2.Nb5 should be played".

b) Richard, the swiss guy said " Sometimes neutralizing the opponent is called for, therefore I'd play 2.Nf3".

c) Emily from Canada looked at the position and said " Obviously you guys are not practical. The Black queen is en prise, there 2 Bxh4 is the right move".

What would you do ?
