MMPT - Viertelfinale: SC Sendling

: Geschrieben von: Jürgen L; Veröffentlicht: 07. Dezember 2022

Am vergangenen Sonntag, dem vierten Dezember, wurde die zweite Runde im Münchner Mannschaftspokal ausgetragen. Dabei traf Zugzwang 3 auf die Mannschaft von Sendling. Die Mannschaftsaufstellung erforderte einige Koordination und letztendlich spielten wir mit Felipe, Jason, Korbinian und Jürgen.

Jürgens Partie auf Brett 4 verließ nie die Remisbreite. Einziger Höhepunkt war das Kompliment des Gegners zum guten Spiel Jürgens nach der Partie. Nachdem ich (Jürgen) dieses Kompliment erwidert hatte, erwähnte mein Gegner dann, dass er erst seit 7 Monaten Schach spielt.

Nur mit Schauer berichten wir über den Verlauf der Partie auf Brett 2. Jason hatte mit Schwarz das Gambitbesteck bereitgelegt und sein Gegner fand sich nach einigen Ungenauigkeiten, nach 12 Zügen, in folgender Stellung wieder:

Korbinian hatte sich auf Brett 3 für eine Berliner Verteidigung gegen Spanisch entschieden. Bis zum 15. Zug war sein Spiel tadellos und er erreichte eine vorteilhafte Stellung

 1. d4 d5 2. c4 c6 3. cxd5 { I usually don't play the exchange Slav, but I saw before the game that my opponent had some bad results against it, and he had previously played a really bad line for black  ( although his opponent didn't played the best way ) . Therefore I decided to see if he'd allow me the same opportunity  ( spoiler alert: he did not ) .}  3... cxd5 4. Bf4 Nf6 5. e3 Nc6 6. Nc3 Qb6 { This is where he deviated. Previously he had played}  ( 6... e6 7. Bd3 Bd6 8. Bxd6 Qxd6 { allowing}  9. f4 { [%cal Gg1f3,Gf3e5,Ge1g1,Gg2g4,Gg4g5,Gd1h5]}  )7. Bd3 a6 { Black refused the b2 pawn. If they took it white would have more than enough compensation. The mainline goes}  ( 7... Qxb2 8. Nb5 { intending a fork on c7}  8... e5 9.

The position is very complex, but white has an edge in the middlegame.}  )8. a3 { this indirectly defends the b2 pawn since after 8..Qxb2 9.Na4 the queen is trapped. This also gives the white queen access to the c2 square after Bg4, without losing the bishop pair to a Nb4 fork. From here on I was on my own.}  8... e6 $2 { I didn't understand this move. Why not develop the bishop via g4 first? I guess he was scared of f3-g4 and a quick attack against his kingside, but I don't think it works that well.}  9. Nf3 Nh5 10. Be5 Nxe5 $6 11. dxe5 $1 { These structures usually favor black, given that his knight is out of squares and his bishop can't develop via the most active square d6. White can also later put a knight on d4 and push his f and g pawns down the board.}  11... g6 12. O-O Bd7 { threatening to exchange his bad bishop with Bb5.}  13. Qe2 $6 { This stops the trade, but my queen occupies the square that my c3 knight wants to use to get to d4 or f4. I played this quickly, but afterwards I wasn't sure it was the best move. White is playing for suffocation, but black has the necessary time to improve his pieces and then break the center with his f-pawn. One can already see that the main theme of this game is prophylaxis.}  13... Be7 14. Rac1 { Occupying the open file. I considered g4, but wanted to play it only after black's king castles short, to prevent counterplay against my king.}  14... O-O { now is the time for}  15. g4 Ng7 { I spent quite some time here to decide how I wanted the kingside structure to look like.}  16.

Unfortunately I thought this didn't work because of}  16... Qd8 17. h4 h6 18. gxh6 Nh5 { where both h-pawns fall and my king looks weaker than black's. The engine disagrees, but this looks quite scary for white from a human perspective.}  ( 18... Nf5 19. Bxf5 gxf5 20. Kh2 ))( 16.

Both}  )( 16. h4 { and} )( 16. h3 { looked a bit weird since black can break the structure with either f6, f5 or h5  ( in any order ) , and it's also a bit slow. Therefore I decided to gain control the open file, given that the f8 rook might be busy in the f-file in the near future.} )16... f5 $2 ( 16... f6 { was what I was expecting from black, but after the game my opponent mentioned he didn't consider it seriously. I was planning to play}  17. Rfc1 fxe5 18. Nxe5 { I had a feeling black was already more than OK, but I had trouble evaluating how good/bad the position was. The computer says black is much better...}  )17. g5 { not opening the f-file. After}  ( 17. gxf5 Nxf5 18. Bxf5 ( 18. e4 dxe4 19. Bxe4 { would allow the d7 bishop to come into the game via c6, and black could use the weak light squares around my king in the future}  )18... Rxf5 { things looks really bad for white because of the pressure on the f-file and the e5 pawn.}  ( 18... exf5 19. Nxd5 ))( 17. h3 { was the other option, but black can double on the f-file before breaking the kingside open with h5, fxg4, f4 or even d4.} )17... Rac8 $2 { was a pleasant surprise! I was worried about}  ( 17... f4 { where after}  18. e4 ( 18. Nd1 { was another idea, but sadly this is bad for two reasons: first it prevents my f1 rook from coming to c1, and secondly it fails for concrete reasons because of}  18... Ba4 19. Rc1 Bxd1 20. Rcxd1 fxe3 { and black is winning already}  )18... d4 19. Nb1 { my light-square bishop became worse than black's, my knight on b1 doesn't have a great place to go and black can contest the c-file. The engine thinks white is much better here, which surprised me.}  )( 17... d4 $1 18. exd4 Bc6 { is the engine's idea, claiming that because of the weak light squares around white's king black is already better here.}  )18. Rfc1 Qa5 19. h4 Rfd8 20. Nd4 { preparing f4 to gain full control of the kingside, shut black's bishops forever and claim that black's pieces are too clumsy to come to the queenside once the game shifts there.}  20... b5 21. Kg2 { controlling the g3 square, so that black's knight can't come to e4 via Nh5-g3-e4. White could have started with f4 as well.}  21... Qb6 22. b4 { trying to stop b4, which after the trade would make black's pieces more active since the b-file would open and the bishops could come to the game.}  22... Nh5 ( 22... a5 { was what I was calculating, but I thought after}  23. Bxb5 $1 axb4 24. axb4 Bxb5 25. Qxb5 $1 Qxb5 26. Ncxb5 Rxc2 27. Rxc2 Bxb4 28. Rc6 { white must be close to winning. So Nh5 was a surprise and I thought black was hoping for an f4 break, given the a5 one didn't work. So I quickly played}  )23. f4 $4 { and a few seconds after making this move I realized I had blundered a pawn and maybe the game. My opponent took his time, so I knew he had seen it}  23... Nxf4+ $1 ( 23... Qxd4 { was also possible, but I thought this endgame should be holdable after}  24. exd4 Nxf4+ 25. Kf3 Nxe2 26. Nxe2 Rxc2 27. Rxc2 Rc8 28. Rxc8+ Bxc8 { since black's only good break is a5, which must be prepared with Bd7 and Bd8, but white is on time to move his knight to b3 and claim it's a draw. Unfortunately my opponent played the other line  ( curiously after the game he mentioned he wasn't so sure it was the best option ) .}  )24. exf4 Qxd4 25. Kg3 { defending the f4 pawn. White is now hoping for some kingside counterplay with an h5 break  ( once the d3 bishop is not hanging with check )  and maybe a perpetual or mate threats down the h-file. The computer says black is winning here with best play, so those were only dreams...}  25... Rc6 $6 { I had calculated}  ( 25... Rc7 $4 26. Nxd5 $1 Rxc2 27. Nxe7+ Kf7 28. Rxc2 Kxe7 { with equal chances, but my opponent played the rook to c6 to avoid this  ( since after Nxd5 Qxd5 the queen defends the c6 rook as well ) . But luckily I also saw a similar idea with}  )26. Nxb5 $5 { and the rook and queen are hanging. Here I thought I was back in the game and already better. My opponent played}  26... Rxc2 $4 { but we both missed the computer line}  ( 26... axb5 27. Rxc6 Bxc6 28. Rxc6 Ra8 $1 { where the computer says black is totally winning because a3 will fall and white's king is very weak  ( not to mention the d3 bishop and kingside pawns ) . Luckily neither my opponent nor me saw this variation and we both thought white was better after trading twice on c6}  )27. Nxd4 Rxc1 ( 27... Rxe2 28. Bxe2 { is even worse.}  )28. Qb2 $1 { This move took me some time. Of course the a6 pawn is hanging, but the queen on b2 strengthens the variation for white, since it defends the a3 pawn  ( which will be attacked once a rook lands on c3 ) , defends the knight on d4 and stands behind the  ( soon-to-be )  passed b-pawn. The knight on d4 makes a good job of controlling the c2 square, preventing any possible Rc2+ fork down the line. Lastly, I had also seen the idea of forcing the trade of rooks for the queen, played in a few moves.}  28... Rdc8 29. Bxa6 R8c3+ 30. Kf2 Bd8 { The check on b6 doesn't change much.}  31. Ne2 $1 { and the queen will give herself for the two rooks, thus ending all black's counterplay and obtaining a winning endgame.}  31... Bb6+ 32. Kg2 R1c2 33. Qxc3 Rxc3 34. Nxc3 d4 35. Ne2 Bc6+ ( 35... d3 36. Bxd3 { doesn't help much since after Nc3 the passed pawns will advance and the king defends the weak f4/h4 pawns for now.}  )36. Kf1 $1 ( 36. Kf2 $4 d3+ $1 { would have been a sad way to end the game.}  )36... Kf7 37. Ke1 Ke7 38. Kd2 { controlling the pawn with the king, and threatening Kd3-Nxd4 if the light square bishop ever leaves the long diagonal.}  38... Kd7 39. Bc4 $1 { preventing the activation of black's king. Here's at play the concept of two weaknesses  ( or three in this case ) : * the e6 pawn  ( which, if lost, would give me yet another passed pawn on the e-file )  * the connected passed pawns on the queenside, which black has to control with his bishops * the d4 pawn  ( which for now prevents the full activation of white's pieces From now on white will threaten one after the other to improve his position and eventually break through. Also note that all piece trades favor white: * after a trade of light-square bishops the d4 pawn will fall and a knight on this square will help the advance of the passed pawns and attack the weak pawn on d6 * after a trade of light-square bishop for knight the king will slowly invade the queenside, as happens later in the game * after a trade of dark-square bishop for knight the white king will easily invade the queenside, since black's bishop can't attack white's weak pawns on f4 and h4 Lastly, a pawn endgame is obviously winning for white.}  39... Be4 40. a4 Bf3 41. a5 Ba7 42. b5 $2 { was an imprecision, since after}  42... Bc5 $1 { white needs to play}  43. a6 { to protect it against a fork on b4. Now the pawns are in the squares of the wrong color: they should be on dark squares  ( which means they cover dark squares ) , and my bishop would cover the light squares. The only good news is that with a white pawn on a6 black can never sacrifice his d4 pawn to go after my kingside pawns since that would be too slow now  ( white would queen his a-pawn ) .}  43... Be4 44. Nc1 $1 { bringing the knight to d3, blocking the pawn and looking at the tasty c5 square.}  44... Bb6 45. Nd3 Bf3 46. Kc2 Be4 47. Kb3 { intending Kb4 followed by either Ka5 or Nc5+}  47... Bxd3 48. Bxd3 { now I saw the win to the end.}  48... Kc7 49. Kc2 $1 { I believe this was more precise than Bc4, since in case black sacrificed his pawn with d3 I would take it with my king, thus controlling the e3 square and preventing an invasion by black's bishop. But now I think this was unnecessary, since white also wins in that variation because e6 falls. Nonetheless I still think Kc2 is a better move since the win is easier, but it's definitely not the only winning one.}  49... Bc5 50. Bc4 Kd7 51. Kd3 Bb6 52. Bb3 $1 { preparing to invade with the king, while still controlling black's passed pawn promotion square.}  52... Ba7 53. Kc4 Bb6 54. Kb4 { zugzwang!}  54... Ke7 55. a7 $1 Bxa7 56. Ka5 { now black's king is one file too far to defend his bishop on b8.}  56... d3 57. b6 Bb8 58. Ka6 d2 59. Kb7 Bxe5 { was his last try, but the whole idea of Bb3 was to control both passed pawns in a single diagonal}  60. fxe5 f4 61. Bd1 { and black resigned. 1-0 This also gave us the match victory by 2.5 x 1.5!}   *

Das bessere Endspiel gewann Weiß mit einigen feinen Zügen und sicherte einen 2,5 zu 1,5 Sieg für Zugzwang 3.
