The Fabulous 10’s: When Scorpions Attack (Each Other)

November 13, 2010

Intra-Scorpion Matchups at the 2010 Arizona State Championship

When two Arizona Scorpions play OTB, it’s always a hard-fought encounter.

In Danny Rensch’s tournament the Copper State International (Mesa 2010) I sacked an exchange to reach what I thought was a promising attack with a well-cooperating queen and knight duo.  However, my opponent Robby Adamson had more resources than I thought, and went on to score a victory and a final IM norm!

Does somebody have that game score? I want to post it here.

More recently, the 2010 Arizona State closed championship is underway.  We’ve already had many Scorp/Scorp matchups.

Here’s an interesting encounter from Round 1.

AZ State Championship  Tucson, AZ  11/12/10  Round 1

David Adelberg (2277) – Mark Ginsburg (2446)  Modern Defense

1. d4 g6 2. c4 Bg7 3. Nf3 d6 4. Nc3 Bg4 Not a scare system, but Timman did use it to draw the solid Lajos Portisch in Wijk aan Zee, 1975 (an excellent tournament book by RHM Press covering that event!).

5. e3 c5 6. Be2 The plan for better or worse is 6. dxc5 Bxc3+!? 7. bxc3 dxc5.   I think Leonid Bass played Adelberg’s way against me in the 1980s.

6…cd 7. ed Nc6 8. d5 Bxf3 9. Bxf3 Ne5 10. Be2 White could castle and leave the B on f3 for the moment.

10…Nh6

White deviates from Portisch's Recipe

11. f4!? Deviating from Portisch-Timman where white put a bishop rather passively on d2.  In that game, Timman’s queen got to d4 via b6 and black was very active, holding a draw comfortably.

11…Nd7 12. Be3 Nf5 13. Bf2 h5 Black cements his knight on f5 but is left with not that much to do.  White has to be a bit better.

14. O-O Bxc3 Not very inspiring.  15. bxc3 Nf6 16. Bd3 Qd7 I really didn’t like my game and offered a draw.  White thought for some time and declined; however his next few moves don’t meet the requirements of the position as Soviet chess analysts used to like to say.

17. Qc2 Now, or soon, I would as white play a rook to the b-file and then advance with a2-a4-a5.  White is better.

17…O-O 18. Rae1 Again, I would play a rook to the b-file.

18…Rfe8 19. Re2?! This is the most serious gaffe so far. The mechanical doubling on the e-file allows black’s next which gives black much needed breathing space.  White should have simply prevented the b5 break.

19….b5!  20. Rfe1 bxc4 21. Bxc4 Rec8! 22. Ba6? A big lemon.  Black is just better after the obvious sac in reply.

22…Nxd5 Of course.  23. Bxc8 Rxc8 And now it’s very hard for white to defend.  Black just stays compact and uses the Q & Knights combination to effectively attack, whereas white’s rooks completely lack coordination.

Very hard for white to hold on in practical play

24. Rc1 Nxf4 25. Re4 e5! This is strong because the black queen gains access to g5 (see 27th move for black).

26. Bg3 Ne6 It’s easy for black to play. The Bishop on g3 isn’t doing anything so black just grabs space and goes back on the attack in a few moves.

27. Qa4 Qe7! Going to g5.  A false trail would be to occupy the a8-g2 diagonal (although tempting) as the g5 square is much more productive.

28. Rc4 Rd8 Just staying out of the way in order to resume the attack momentarily.  29. Qa3 Qg5 The end is near now.  30. Qb2 h4 31. Be1 Nf4 And now it’s resignable; white loses back material with a two-pawn deficit.

The Two Knights Attack

I credit GM Yermolinsky with my coherent middle-game play.   Out of the many times I played him, in one specific game (I think in Las Vegas), he instructively time and again put his pieces where they coordinated and stayed compact.  He explained his thinking process as just that, staying compact.    My 25th through 28th moves were all exactly that – a compact formation that can uncoil and grab more space.

32. Qd2 Nothing else to do.   32…Nd3 and 32….Ne2+ were both threatened and white can’t stop both.  32…Ne2+ 33. Qxe2 Qxc1 34. Rc7 Rb8 It’s over.

35. Qd2 Rb1 36. Qxc1 Rxc1 37. Kf1 Rc2 38. Rxa7 Ne3+ 39. Kg1 Rxg2+ 40. Kh1 h3 Completing white’s king’s entombment.  41. a4 Ng4 42. a5 Rxh2+ 43. Kg1 Rg2+ 44. Kh1 Ra2 45 Kg1 h2+ and white finally resigned.

0-1

To Adelberg’s credit, he bounced back in Round 2 and in a sharp Sozin Najdorf as black, defeated fellow Scorp IM Aldama.

In other Scorp action, Levon Altounian won with a 2. c3 Sicilian vs NM Nick Thompson and when I left the playing hall tonight after drawing IM Altounian, NM Thompson was battling NM Adelberg.

After 4 rounds I was in the lead with 3.5 out of 4.  My nearest competitors were Altounian and Adelberg with 3 out of 4.  They were due to play in the last round and I had black against fellow Scorp, IM Dionysio Aldama.    I had just come off a very long game, eventually winning in a Sicilian Kan vs NM Nick Thompson.  Altounian wound up making a draw with white vs Adelberg’s solid Slav, so it turned out all I needed was a draw for clear first.  The problem, though, was that I achieved the most unpleasant of situations: a winning position in the opening!

Round 5 (final round)

IM Aldama – Ginsburg  Tricky Eugene Meyer Sicilian

1. e4 c5 2. Nc3 e6 3. f4 d5 4. Nf3 Nc6 5. Bb5 Nf6 6. Ne5 I think 6. e5 is much more common, but black will try the same trickery as the game (early disrupting c5-c4).

6….Qc7 7. Qe2 (7. Qf3!? is a move that occurred to me at the moment, pressuring d5, not sure if it’s anything real) 7….Be7 8. O-O O-O 9. Bxc6 bxc6 10. d3 c4!

Eugene Meyer move

As shown and played by Eugene Meyer.  Black achieves excellent dynamic play.

11. dxc4 Ba6 12. Bd2? A weak move.  White needs b2-b3.  12…Nd7 13. exd5 cxd5 14. Rfe1

After the game my opponent asked me what I would play on 14. Nxd7.  Can I take on c4, I inquired?  No!  14. Nxd7 Bxc4 15. Nxd5!! wins for white!  If I stopped to think here, I would find 14. Nxd7 Qxd7! and black has a great game.

14…Nxe5 15. dxe5 Qxc4?! Although black of course stands well now, there was no reason to pass up 15…Qb6+! 16. Kh1 Qxb2 17. Rac1 Bxc4.  I was worried that my pieces could not easily aid my king after, e.g, 18. Qg4, but of course that’s not a real attack.

16. Qxc4 Bxc4  17. Nd1 White needs to regroup his terribly placed pieces. 17…Rfc8 18. Be3 f6 An interesting moment. I also have 18…f5!? and I also have 18…Ba6!? just leaving the f-pawn alone for the moment. 

19. Bd4

Position after 19. Bd4

Here, I could play the “Dzindzihashvili bypass maneuver” with 19…f5!? with the idea of further space gains on the kingside, g7-g5, and so on.  White can do little. I am calling it this because I saw GM Roman do it once – offer a pawn exchange then craftily bypass the next move, ruling out en passant!  My chosen move is not bad either.

19…fxe5 20. Bxe5 Bc5+ 21. Ne3 White is barely holding on.  I started wondering about Rc8-f8-f1+ but that leads nowhere.

21…Ba6 22. c3 Bd3 At this point Adelberg looked solid (he in fact did hold the draw) so I offered a draw; I still thought black was better.  Aldama refused and played:

23. Rad1 Be4 24. b4 Well, white has to do something! 24…Bb6 25. a4

Position after 25. a4

25…a6? I played this inaccurate move quickly.  After the game Altounian pointed out the very strong and fairly obvious 25….a5! with the idea 26. b5 Rc4!.  Clearly my brain was not working too well after the prior rounds (some of them very long).    To make matters worse, Aldama was going off for quick rejuvenating smoke breaks quite often.  He was gaining energy!

26. a5 Ba7 27. h3 Rc4 At least I found this safety move -coupled with black’s next it *should* remove all danger!

28. Kh2 Bxe3 Of course this plan handing over the bishop pair was not required and perhaps even suspect, I was just afraid of any specter of N vs B endings.  But why give up the bishop pair like this?

29. Rxe3 Rf8 30. Rd4 Rf2! This rook never should have left the seventh rank!

31. Rg3 g6 How can black lose?   The problem was I started thinking about using both rooks to attack white’s king and win!

Position after 31....g6

32. Rg4 I had no idea what white was up to besides the Rgxe4 trick. I considered the safe 32…Rxd4 with a complete draw but decided just to bring the c-rook around to the f-file.  A bad practical decision!

32…Rc8 Not a bad move, but white now plays the shocking:

33. Rgxe4! The only chance to get out of the bind!  I completely fail to reorient.

33…dxe4 34. Rxe4 A transformation!  Black should now be paying attention to the majority and find the obvious 34…Rc2! defending and keeping the pawns at bay.  Needless to say, black is fine there.  Altounian’s computer said black is practially winning!  Instead I unfurled

34…Rf5?? An example of not thinking anymore.  I was luring white to play the incomprehensible 35. g4? then I play 35…Rf3!.  See the note to black’s 30th move!

He quickly played instead the unpleasant: 35. c4! and now white’s pawns are a huge headache.  I saw nothing better than the lame game continuation:

35…Kf7 36. b5 Ke7 37. b6 Rxe5 38. Rxe5 (38. b7? Rec5) 38…Rxc4 39. Rb5! Yes, I saw that one coming.  Not a nice turn of events with white very low on time but with moves like this available.  It now appears that white wins, barely, in the upcoming rook ending by one tempo.  Brutal!

Position after 39. Rb5!

39….Rc8 40. b7 Rb8 41 Rb6 Kd7 42. Kg3 e5 43. Kf3 Kc7 44. Ke4 Rxb7 Fortunately white loses by one tempo if he plays 45. Rxb7 here, at least that is what I calculated. I guess Aldama thought the same thing so he played 45. Rxa6 and now I found 45…Rb3! creating problems by going for the g3 square!   Drama continues!

Position after 45...Rb3!

A very interesting rook ending.  I think white played the right way now:  46. Rf6 (!) Rg3 47. Rf2 Kb7 48. Kxe5.

At this point black can go for the 48…g5 move to keep the rook on g3, but it appears he gets broken down by zugzwang:  white puts the rook on the a-file and keeps the white king close to the g5 pawn; black runs out of moves.  Similarly, 48…h5 and 49…h4 also lose to a zugzwang.  Black tried another option which also lost (barely).

48…Rg5+ 49. Kf6 Rxa5 50. Kg7 Rh5 This position is a little tricky!  51. Rf3! White aims for g2-g4 trapping the rook.

Position after 51. Rf3!

51…g5 Trying for a g5-g4 trick.

52. Rf6!   White has it all worked out. 52…g4 Last try!  53. hxg4 Rg5+ 54. Kxh7 Rxg4 55. Rg6 With a book win. G-pawns are surprisingly easy to win.

55…Rh4+ 56. Kg7 Kc7 57. g4 Kd7 58. g5 Ke7 59. Ra6 Rh1 60. Re1! and white won shortly.

1-0.

Amazingly after I resigned I learned that I had won the tournament on tie-break (because in round 1 I defeated one of the co-winners).  Never before has this happened to me.

Wow.  Even so, it was a bitter pill to lose this game considering the opening!

Postscript

I found a PDF file documenting prior Arizona State Championships. I don’t know who the author of that document is (the person that contributed the updates up to 2009). Curiously they omitted Angelina Belapovskaia who tied with me in 2004, I believe.   That tournament was played in Mesa, Arizona at one of Danny Rensch’s chess-house sites.    I was surprised to see I had tied for first apparently three times before (I thought it was twice before).  So now, apparently, I have tied for first four times!

In other personal State Championship historical news, in 1982, I won the Maryland version by defeating Richard Delaune in the last round.   This was actually a really good game that you can find on chessgames.com.  In 1989, I tried to win the NY State in Albany NY (defeating IM Shirazi in a nice game that featured a highly unusual queen sac) but I believe some Grandmaster luminary took top honors that year.  All I can remember about Albany 1989 is visiting a jazz club where Grandmaster Larry C drummed on the table to express solidarity with the musicians.  I haven’t been that active, clearly, in trying to win state honors here and there.  I lived in New Jersey for a while but never tried that one.

Baby Mark in 1960 had not yet conceived of “state championships”.

Manhattan Chess Club, 1988

I won the Manhattan CC Championship (a now defunct club, located at the glamorous Carnegie Hall, 57th and 7th, NYC) twice in 1988 and 1990.  Sandwiched between these was my unsuccessful run at the NY State Championship in Albany 1989.

The Fabulous 10s: US Chess League Benoni Insanity

September 10, 2010

Channeling Gashimov

From Week 3 action:

Joel Banawa (LA Vibe) – Dionisio Aldama (Arizona Scorpions)

Modern Benoni

1.d4 Nf6 2.c4 c5 3.d5 e6(?!)

Very combative and probably not good according to the latest word in theory in this move order.  For adventurers, look at 3…a6!? hoping to get e6 in soon under better circumstances!

Too combative?

4.Nc3 exd5 5.cxd5 d6 6.Nf3(?)

As far as I know, the Modern Benoni in this move order is still considered dubious due to the straightfoward e4, f4, and Bb5+ despite some sporadic efforts by Topalov in the 1990s. That’s why it’s far more often seen after white commits his knight to f3.

6…g6 7.h3 Bg7 8.e4 0-0 9.Bd3

As recommended by Yermolinsky in the “Road to Chess Improvement” book.  Yermo scored several convincing wins in this clear-cut “central” strategy.

Previously thought to be very dubious for black, this setup has been re-invigorated thanks to the efforts of young world-class Grandmaster Vugar Gashimov.  Indeed, in the analysis room at the playing hall for Arizona, I instructed John Gurczak to kibitz “Gashimov!” around this point.

8…a6 10.a4 Re8

Igor Ivanov used to say categorically that any Rf8-e8 move is useless in the Benoni because the Rook needs to be on f8 to support a later f7-f5.

11.0-0 Nbd7 12.Re1 Rb8 13.Bf4 Qc7 14.Nd2 Ne5 15.Be2

I guess white wanted to observe h5 to prevent Nf6-h5. This position is fully acceptable for black.  But now mysterious things start to happen.

15…h6 16.Rc1 g5

I’m not sure about this move or the prior move.  White is gearing up for his strong 18th.

17.Bg3 Bd7 18.b4! cxb4 (?!)

In light of the unpleasant developments following this move, black should already be seeking alternatives.

19.Nb5 Qb6 20.a5!

Now it’s crazy (probably crazy bad for black).

Queen Quandary

20…Qxa5

What I wanted to see here was 20…Qxb5!!? 21. Bxb5 Bxb5, although 22. Bxe5 takes out most of the fun.

21.Nxd6 Ba4 22.Nb3 Qd8(?)

Here, I was expecting 22…Bxb3!? 23. Qxb3 Qa3!? with counterplay.

23.Nxe8 Nxe8 24.Qd2!  Now white is just winning.

Bxb3 25.Qxb4 Bxd5 26.Red1 Nc6 27.Rxc6?

White gets carried away.  27. Qe1 wins material.

27…Bxc6 28.Rxd8 Rxd8 29.e5 Nc7

Now black is very compact and white cannot break down the formation.

30.Qb6 Rc8 31.Bc4 Ne6 32.f3 Bf8 33.Kh2 Bc5 34.Qb1 Re8 35.Qf5 Bf8 36.Bd3 Bg7 37.h4 a5 38.hxg5 hxg5 39.Bf2 Rd8 40.f4 gxf4 41.Bh4 Rxd3 42.Qxd3 Bxe5 43.Qf5 Bc7 44.Kh1 a4 45.Be7 Bb6 46.Qg4+ Kh7 47.Bf6 Kh6 48.Kh2 Be4 49.Qg8 Bg6 50.Qa8 Bf5 51.Qxb7 Kg6 52.Be5 Bd4 53.Bd6 Bc5 54.Bxc5 Nxc5 55.Qc6+ Ne6 56.Qxa4 Kf6 57.Qc6 Bg6 58.Kg1 Kg5 59.Kf2 Kg4 60.Qd5 Bf5 61.Qe5 Bg6 62.Qe2+ Kf5 63.Qb5+ Kg4 64.Qe5 Bf5 65.Qc3 Kg5 66.Ke2 Bg6 67.Kd2 Kg4 68.Qh3+ Kg5 69.Kc3 Bf5 70.Qf3 Bg4 71.Qf2 Bf5 72.Qf3 Bg4 Game drawn by mutual agreement 1/2-1/2

Quite the tightrope act from Aldama!  Arizona wound up decisively winning the match, 3 1/2 to 1/2.
