We will see the crucial game of round 8 for the 1st place in the Polish Championship. At that moment the young Polish GM Duda was leading with an amazing 6/7, followed by Gajewski on 5.5/7 and Wojtaszek on 5/7. A win was almost a must for the Polish Nr1, who has been the second of Anand for many years. What is hard to say is if Radoslaw even made one move by himself in the current game!? We will witness an amazing preparation in an extremly sharp line of the Najdorf.

View the game or check out the "text + diagrams" version below.


Results of the Polish Chess Championship: 1. Radoslaw Wojtaszek (2713) - 7/9; 2. Grzegorz Gajewski (2631) - 7/9; 3. Jan-Krzystof Duda (2563) - 6/9. Source.

Duda,Jan-Krzysztof (2563) - Wojtaszek,Radoslaw (2713) [B96]
Mistrzostwa Polski Warsaw POL (8), 01.04.2014
[Arkadij Naiditsch]
 
1.e4 Duda is just 16 years old and seems to be great in tactical positions. He is playing the Najdorf himself with Black, so from the beginning it was clear that the game was going to be an extremely fought one.
1...c5 The Najdorf is also the main opening of Wojtaszek. Maybe it is because he is working with Anand or just because he worked by himself a lot, but Radoslaw became a theoretical beast, especially in his main repertoire.
2.Nf3 d6 3.d4
Sometimes when you are young, you want too much and too quickly... [Looking at the tournament situation and realizing that the opening knowledge of your oponent is probably bigger than yours, a positional line like 3.Bb5+ was probably a better practical choice.]
3...cxd4 4.Nxd4 Nf6 5.Nc3 a6
So we are in the main position of the Najdorf.
6.Bg5 This is probably the most concrete and sharp answer for White. [During the Candidates, we saw a lot of games on 6.h3 but of course this can't be the critical line to put the Black into trouble. A nice game to watch here is Anand-Mamedyarov, where Black equalized quickly.]
6...e6 7.f4 h6 Not that long ago Black started to include 7...h6 before playing Qb6. [For many years 7...Qb6 was one of the main moves in the position but it seems like at the current moment the position after 8.Qd2 Qxb2 9.Rb1 Qa3 10.e5 is evaluated as dangerous for Black.]
8.Bh4 Qb6




9.Qd2 Not the only option for White. [9.Qd3 and; 9.a3 are the other main choices, especially since 9.a3 makes sense now, to try and make use out of Black's h6Bh4 inclusion other than by playing Bf2.]
9...Qxb2
The beginning of a very sharp and forced line.
10.Rb1 Qa3 11.e5 [Another main line was 11.f5 but it seems that it leads to a draw after: 11...Be7 12.fxe6 fxe6 13.Bc4 Nxe4 14.Nxe4 Bxh4+ 15.g3 Bg5 16.Nxg5 hxg5 17.Nxe6 Bxe6 18.Bxe6 Qxg3+ 19.hxg3 Rxh1+ 20.Ke2 Rh2+ 21.Ke3 Rxd2 22.Kxd2 Ra7 with an equal position in Vallejo-Morozevich 2011.]
11...dxe5 12.fxe5 Now Black has 2 choices:



12...g5! is clearly the most critical continuation. [12...Nd5 is the other main choice, but now another very forced line leads to a dangerous position for Black: 13.Nxd5 exd5 14.e6 Bxe6 15.Nxe6 fxe6 16.Bd3 Be7 17.Bg6+ Kd8 18.Bxe7+ Qxe7 19.00 Nd7 20.Rf7 Qc5+ 21.Kh1 Rf8 22.Rxg7 Rf6 23.Bd3 and I think Black is risking clearly more than he can gain here, like in Naiditsch-Yilmaz 2013.]
13.exf6 gxh4 14.Be2
Of course this is all still theory and Wojtaszek has even played a game here. The position is very forced and hard to evaluate. A lot of crazy computer lines, a lot to remember. Basiscally White is either going to mate or he is going to be in trouble because he is a pawn down, has no bishop pair and a bad pawn structure.
14...Qa5!
A very strong move and of course still a theoretical one. The black queen is going to take a great position on g5 and is now preventing White from playing Bh5.
15.00 Nd7 16.Kh1 We are still following the game of Nisipeanu-Wojtaszek from 2011. But a lot of new games have also been played in this position.
16...Qg5 We are slowly reaching the main position.
17.Rf4 e5
Black is forced to accept the challenge as White wanted to play Ne4 with a winning position.
18.Nd5
White is sacrificing a piece to try and crush Black's position.
18...exd4 19.Qxd4 Kd8!
This is still theory and the only move for Black. We finally reached the main position for analysis. as I analysed the current situation a lot myself, because it is critical for the evaluation of the line with 7...h6. But even with a good computer it is very hard to make a clear suggestion of what to do next or to be sure about the correctness of the analyses as the position is very complex.



20.Bg4N
This move seems to be a novelty, but clearly it was not a surprise to Wojtaszek. The white queen has no good squares now. [Nisipeanu continued with 20.Rd1 and Black replied with the very strong 20...h3! 21.g3 Bd6 and after a tactical battle Black won the game.; 20.Ne7!? seems to lead to a forced draw. 20...Qe5 21.Qd2 Bxe7 22.fxe7+ Qxe7 23.Bg4 What a crazy position, but computers are very strong here: 23...f5! Strangely this is the best move for Black here. 24.Rxf5 Re8 25.Rd5 b6! 26.h3 Kc7 27.Qxh6 Rb8 28.Qf4+ Kb7 29.Qd4 Kc7 30.Qf4+ With a draw like in Guseinov-Areschenko 2013.]
20...Bc5! 21.Qd2 [at 21.Qc4 b5 Black would win an important tempo for development here.; 21.Qd1 looks bad because White will never have Rd1 to put pressure on the d7 knight.]
21...Bd6!!
Such a move is just impossible to find over the board. It is clear that Wojtaszek knew it and yes, chess is sometimes a game of work!
22.Qa5+
This human move is definitely losing. [After 22.Rd4 Qxd2 23.Rxd2 Nc5 Black should be close to winning.; 22.Rd1! seems to me to be the only move which should be considered. 22...Rb8 and now White has a very big range of moves to choose from. For those who like computer analyses, this is a great position to look for crazy lines. In my opinion, the position is about equal.(Of course not 22...Bxf4 23.Nxf4 and White's pressure on d7 is deadly.) ]
22...b6
I guess Duda was still very happy here, not seeing what was coming just 2 moves from now...
23.Rxb6
White's attack seems to be crushing.
23...Bc7! The only move. [23...Nxb6?? 24.Qxb6+ Ke8 25.Qxd6 with an easy mate to follow.]
24.Bxd7
Black's positi on seems to be lost, but in fact it is winning because of the amazing next move:



24...Qe5!!
This is the key move which Black clearly had to know before playing 21...Bd6. It looks strange, but White can just resign now! Black wants to play Qa1 and defended his bishop on c7. There is no way for White to defend all his pieces. [After 24...Bxd7? White would win the game on the spot by playing 25.Rb8+! Rxb8 26.Qxc7+ Ke8 27.Qxb8+ Bc8 28.Qxc8#]
25.Kg1
This move is losing, but it seems like there was already no escape for White. 



[After 25.h3 Bxd7 Black is just a piece up for no compensation.]
25...Rb8
A nice move. [25...Bxd7 would lead to a slightly more tricky position, as after 26.Qc5 White would keep some practical chances 26...Re8 although Black's position should be winning of course.]
26.Qb4
White can't defend the b6 rook. [Of course White is also lost after 26.Rxb8 Bxa5 27.Rxc8+ Kxd7 28.Rxh8 Qxd5 with an easily winning position for Black.]
26...Bxb6+
Black is just a full rook up.
27.Nxb6 Qe3+ We could see one more time how much chess has changed. On the top level, analyses are deep and players have to remember a lot not to get in deep trouble in the early stages of the game.
