SWIERCZ, Dariusz

Aug-06-10  polarmis: He's started with 3/3 at the World Junior Chess Championship. It'll be interesting to see if he can push on now from the 2500 mark - in a recent interview the President of the Polish Chess Federation outlined Darek's new sponsorship program funded by Microsoft:

black position is already a bit dangerous, he should have moved the bishop somewhere instead.... 67...gf3?? is already losing. 68. gxf3 Bxf3 69. Be2!

Nov-24-10  slomarko: Dariusz won the Cultural Village tournament and qualified for the Corus C tournament. Congratulations!

Nov-26-10  polarmis: Thanks, Slomarko - I'd actually seen the first few rounds of this tournament and then forgotten about it (after three draws I thought the chances of him reaching Wijk were slim). Anyway, I've now written a bit about Świercz at the bottom of this post:

It's funny that in the final round Darek's trainer beat the other player who could have finished first!

Nov-26-10  slomarko: polarmis, very good article! I have followed the tournament and I have to say that Darek was a bit lucky. For example in the game against that Indian guy he was a pawn down and I think close to losing at one point but managed to save it. In the last round his position also looked a bit suspect to me. But anyway he never lost faith and fought on and as for everything in life in chess you need a bit of luck :D
Feb-15-11  polarmis: Nice game today at the Polish Championship today:

Marcel Kanarek has just played 21. Nc3. The combination that Swiercz plays isn't hard to see, but just glancing at the position you wouldn't really expect the c3-knight to be taken by the h6-rook in only 3 moves!

Can you recall what issue of CT you wrote of the ending to the game <Swiercz-Burg Cultural Village Tournament 2010>?

Jeff Hall to Alexander
show details Jan 17
The game was played in late November 2010.

<It's the great self-blocking 69 Bf1-e2! Bf3xBe2 70 Nf4-g2#.> I cannot find it in my issues of Chess Today.

If yoo don't have time, it's no problem. I was just hoping that you had a faster way of searching back issues then I did.


Aug-15-11  TugasKamagong: Finished in a tie with Hovhannisyan, but winner after the tiebreak. Great show, 2011 WJC in Chennai. Congratulations, Darek!
Aug-15-11  siamesedream: Congrats to Darek for winning Gold!
Aug-15-11  twinlark: Well done and congratulations on winning the World Junior Championship.

  Penguincw: Dariusz Swiercz won today with a slick combination.

Black to move.

The last move is a fork with the bishop and rook. If 60...♗xd4 then 61.b8=♕ g1=♕ ♖xg1 ♖xg1...

and it's a win...


♔♕♙ vs. ♔♖♗♙

Superior (White) 43.6%
Draw: Happens 56.4%

click for larger view

less than half of the time. This is someone rated lower than you, and you have white. It has to be a win. Plus, you're at -1.

Instead, what was played was 60...g1=♕ 61.♖xg1 ♖xg1 62.♗xe5 1-0.

click for larger view

Brilliant! Very natural is to grab the rook, but I can't say it's a win.


♔♗♙♙ vs. ♔♗♙

Superior (White): 48.4%
Draw: Happens 51%
Inferior (Black): 0.6%

Endgame Explorer: BPP vs BP

However, grabbing the bishop is winning. The rook can not sac itself for the pawn, because the king covers b1 and the black pawn stops black from getting to g8.

Also, checks can only last very long.

62...♖g2+ 63.♔b3 and black can not check on g3 because of the bishop.

Lastly, black can not even gain the a3 pawn because a1 and g3 are both covered.


♔♕♗♙ vs. ♔♖♙

One example: V Takhtarov vs V Vepkhvishvili, 1970

The superior side (in that game black) eventually won. :)

Swiercz's 69 ♗f1-e2!! is a -stupendously- brilliant move.

What does it do?

1) <INTERFERENCE>: it <CLOSES THE LINE> of the <DEFENDING> Black f3-bishop to the critical d1-sq to threaten the <SNAP MATE> 70 ♖d4-d1# while also putting the <UNPROTECTED> Black f3-bishop <EN PRISE>.

2) <SELF-BLOCK>: 69 ... ♗f3x♗e2 results in the light-squared Black bishop <BLOCKING> the important <FLIGHT SQUARE> e2-flight of the Black e1-king, leaving His Majesty <STALEMATED>.

3) <DEFLECTION>: the Black f3-bishop cannot <PROTECT> the e2-flight and also <PROTECT> the g2-checking sq.

Brilliant move by Swiercz at a clutch time: winning this game won the <2010 CULTURAL VILLAGE TOURNAMENT> for Swiercz, earning him a spot in the <2011 TATA STEEL C> group.
