[Result "0-1"][ECO "E32"]

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 O-O 5. a3 Bxc3+ 6. Qxc3 b6 7. Nf3 Bb7 8.

e3 d6 9. Be2 Nbd7 10. O-O Ne4 11. Qc2 f5

12. b4 Rf6

Note the bishop is on c1

13. d5 Rg6 

Here the variation 14 Nd4 Qg5 15 g3 Ne5! leads to this position

(please note that 15..ed5 16ed5 Bd5 17 Bc4! led to White winning Kramnik-Polgar 2005) This exchange sac was played by Grishuk on 16 Nxe6 Rxe6! 17 de6 Qg6 with attack !

14. Bb2 c5  (another idea would be 14..e5)

15.Rad1 exd5 16. cxd5 Rc8

 17. Qb3 a6 18. Nd2 Nxd2 19. Rxd2 b5 20. Qd3 c4 21. Qd4 Nf6 22. Bf3 Qd7 23. Rc1 Re8 24. g3 Rh6 25. Bg2 Ne4 26. Rdd1 Qf7 27. a4 Re7 !

this moves protects g7 and b7, so the black queen can join the attack on h5.

Black has put a knight on e4 again ( the first one got exchanged on d2 with white's knight).

28.axb5 axb5 29. f3? Qh5!

With a winning attack sacrificing the knight on e4

30. fxe4 Qxh2+ 31. Kf2 fxe4 32. Rc2 Rf7+ 33. Ke1 Qxg3+ 34.

Bxg7 Qb1+ 41. Kc3 Rc1+ 42. Kd4 Rd1 0-1

Sicilian 2Nc3 Nc6 3Bb5!? trap

This occurs after 1e4 c5 2Nc3 Nc6  3Bb5 Nd4 4Bc4

<

4..g6 5 Nge2 Bg7 6 Nd4 cd4 7Qf3! 

Here Black can play 7..Nh6 or 7..Nf6 but the most natural human move is 7..e6?! which leads to the trap White has set up !

7..e6?! 8 Nb5 d6 9Qa3!

Black has to defend d6 and play 9..Ke7

White has exploited the weaknesses of dark squares after 5..Bg7 by targetting c7 and d6 playing Nb5 as Black didn't have time to play a7-a6.

after 9..Ke7 10c3! white is better. You Hifan won against Pia Cramling in 19 moves.

Note that Black can try 8..d5 instead of 8..d6 but White has 9Qg3! with Nc7+ winning the exchange.

Owen defense ..b6,..Bb7 with Nc3 white

The main position to analyze is after the moves

1 e4 b6 2 d4 Bb7 3 Nc3 e6 4 Nf3 Bb4 5Bd3 Nf6

Official Website

Owen Defense B00. Nc3,Nf3,Bd3 lines for white , ..b6,..Bb7,e6,Bb4 for Black


Nc3 gives more options to Black versus quick Bd3,Qe2 with c3/Nd2 options

1..b6,..Bb7 Owen Defense: White repertoire

Official Website

Quick repertoire against b6,Bb7,e6 plans for Black. Owen Defense B00


Main idea is Nf3,Bd3,Qe2 and not playing e4-e5 too quickly.
Another tip is not committing to Nc3 early: maybe c3,Nd2 are needed. No Bb4 for Black

Main Game is Dorfman-Miles 1992 where I am giving improvements for white - Black ended up winning that game. Also C. Bauer move order 6 d5!? with e4,d4,Bd3,Qe2,Nf3 is worth noting

Sicilian Taimanov repertoire for Black against Be3,Qd2,0-0-0,g4 played by White (B48)

http://view.chessbase.com/cbreader/2018/7/12/Game26963484.html

Typical position Taimanov:
White played Be3,Qd2,f3,0-0-0
Black played Qc7,Ne5,b5 leaving king in the center.

Game can become quite sharp

Sicilian Najdorf Theory: A variation for White !

Key Position (Tabiya) after 7 Nde2!?

This is how we reach the diagram:

1e4 c5 2 Nf3 d6 3 d4 cd4 4Nd4 Nf6 5 Nc3 a6 Najdorf Defense

6Be3 e5 The most principled answer. On 6..e6, White can play 7 Be2,0-0,f4 or 7f3,8Qd2,90-0-0 followed by g4 which are both good plans for White.


7 Nde2!?

Which is GM Nisipeanu's move and we reach the diagram above. This is an interesting weapon against the Popular Najdorf for White.

In the next 2 days, we will look at how to build a repertoire for White in this variation.
