Here are my games.  I took a bye in the 3rd round to drink and gamble, making my effort a 6-rounder.

Round 1.

M. Ginsburg – S. Higgins (attended some Robby Adamson camps)

1. Nf3 Nf6 2. c4 Nc6 3. d4 e6 4. a3 d6?! 5. Nc3 g6 6. d5! This move gives an edge in all lines. As black, I like to try the Tango a little differently:  in ICC blitz 4…g6!? 5. Nc3 Bg7 6. e4 d5!? is recommended with crazy Gruenfeld-like complications.  I haven’t looked up if that particular try has been seen OTB.

6…Ne7 7. e4 e5 8. c5! Bg7 9. Bb5+ Nd7 9..Bd7 is quite playable.

10. b4 The computer is quick to point out the logical 10. cxd6 cxd6 11. O-O O-O 12. Be3 f5 13. Ng5 but the text move is all right.

10… O-O 11. O-O h6 12. Bb2 f5 13. Bc4 Kh8 14. Rc1 Nf6 15. exf5?! Cleaner is 15. Nd2! with the possible line 15…f4 16. Be2 g5 17. cxd6 cxd6 18. Nb5 Ne8 19. Bh5!! (a fantastic move to gain c7) 19…Nf6 20. h3 a6 21. Nc7 Rb8 22. Be2 and white is dominating; he can choose when to play Ne6 with crushing effect.  This is exactly what white wants – a route to e6.

15… g5?!

Puzzle. White to play...

16. Re1? Very weak.  The computer points out the elementary tactic 16. h4! g4
17. Ng5! hxg5 18. hxg5 Bxf5 19. gxf6 Bxf6 with a big edge to white.  For whatever reason, I played my move fast, never bothering to look for anything.  A sign of first-round laziness?  At least I was well ahead on time at this point.  I had some vague notions of Bishop back to f1 and clearing the c-file.

16… Bxf5 17. Bf1 17. h3!? Ng6 18. Qb3 Qd7 19. c6!? bxc6 20. dxc6 Qxc6! 21. Bd5 Qe8 22. Bxa8 Qxa8 and black has good compensation.

17… Bg4 18. Be2 Bf5 19. Qb3 Ne8? No reason for this retreat. 19… g4 20. Nd2 h5 is all right.

20. Nd2 Ng6 21. Bf1?! A continuation of a second-best idea.  The obvious reflex denying the f4 square, 21. g3! gives white a pleasant edge.

21… Nf4 22. Nde4 Qe7 23. Nd1 Nothing wrong with the solid 23. f3! — the game move somehow works out after a pair of knights comes off the board.

23… Nf6 24. Nxf6 Rxf6 25. Ne3 Bd7? Now white breaks through and should be winning.  But since both players are in time trouble, black more than white, crazy adventures await.

26. cxd6 cxd6 27. Rc7 Qd8 28. Rec1 b6 29. Qc2 Rf8 30. g3! After the game, I thought this move was terrible giving black all kinds of chances, but it’s actually correct and the fastest win.

A more practical move is 30. Qe4 with domination.  Black can barely move.

30… Nh3+ 31. Bxh3 Bxh3 32. Qg6? A huge lemon.  Consistent is 32. g4! locking out the bishop on h3.   32. g4! Qf6 (note that 32… Rf4 is met by an unusually nice combination: 33. Qg6 Qf6 34. Rc8+ Rxc8 35. Rxc8+ Bf8 36. Qxf6+ Rxf6

Position after 36...Rxf6 (analysis)

37. Bxe5!! {Wow!} dxe5 38. d6 Rxd6 39. Rxf8+ Kh7 40. Rf3 and wins the errant bishop!

Returning to 32. g4 Qf6, 33. Nf5 Rg8 34. f3 h5 35. Qe4 and white has things under control and wins.

32… Qf6 My preliminary calculation had 32…Rg8 33. Qh5 “with the dual threat of Qxh3 and Rxh6 mating” — but the rook on c7 really cannot jump to h6 like that.  Also I hadn’t even noticed the game defense.

33. Qxf6 Rxf6 34. g4 Late, but still good.  Not as good, though.

34…Raf8 35. Nf5 Rg6?! A better try is 35… h5! 36. Rxg7 (The optically “nice” 36. R1c2 is insufficient due to a fantastic resource:  36… Bxg4 37. f4 (37. Nxd6 Kxg7 38. Bxe5 Kg6 39. Bxf6 Kxf6 40. Ne4+ Kf5 41. Nd2 Ke5 42. Rc7 Rc8! is equal) 37…Rxf5 38. Rcc7 Rc8!! {Wow!} 39. Rh7+ Kg8 40. Rcg7+ Kf8 41. Rd7 Kg8 and draw!

36. f3?! Another miscue.  The players have no time. Correct is the difficult 36. R1c6!! Bxg4 37. Nxd6 Bf3 (37… Kg8 38. Rxa7 Rf4 39. Rcc7 Bf8 40. Nc4 Bh3 41. Ne3 Re4 42. Rc6 and wins) 38. Nf7+ Kh7 39. Nxe5 Rxc6 40. Nxc6 Rg8 41. Bxg7 Rxg7 42. Ne7 and wins.  This is the kind of line that needs a little time to see.

36… h5! Very confusing.

37. Nxd6? White has become totally confused.  He should play 37. gxh5! Rgf6 38. Rxg7! forced — (38. Nxg7??  Rxf3  wins for black: 39. Nf5 R3xf5 40. Rc8 Rxc8 41. Rxc8+ Kh7 42. Rc1 Kh6 and wins) 38…Rxf5  (if 38…Bxf5 39. Rxa7 and white should win) 39. Rcc7! R8f6 {Forced.  But now comes an amazing combination:

40. Rh7+ Kg8 41. Rcg7+ Kf8 42. h6 Rf7 A good tactics puzzle now.  White to play and win.

Note in passing 42… Rxh6 43. Rxh6 Rxf3 44. Rxh3 Rxh3 45. Rxa7 and white wins.

White to play and win. Position after 42...Rf7 (analysis)

43. Bxe5!! {A great shot.} dxe5 (43… Rxf3 44. Rxf7+ Rxf7 45. Rxf7+ Kxf7 46. h7 wins) 44. d6 Rxf3 (44… Rxg7 45. hxg7+ Kg8 (45… Kf7 46. d7) 46. d7 A quite unusual combination hanging the rook and having black’s pieces blocked from the promotion by interference! 46…Kxh7 47. d8=Q Kxg7 48. Qd7+ Kg6 49. Qxa7 Rxf3 50. Qxb6+ Kf5 51. Qa6 and wins) 45. Rh8 mate!)

37… hxg4? Black only had seconds left. 37… Rxd6 38. Rxg7 Kxg7 39. Bxe5+ Rdf6 (or 39… Rff6 40. gxh5 Kf7 41. Bxd6 Rxd6 42. Rc7+ and white might draw) 40. gxh5 Kf7 41. Rc7+ Ke8 42. Bxf6 Rxf6 43. Kf2 with chances to draw.  That would be embarrassing indeed but at least white is not totally lost.

38. Nf7+ Kg8 39. Nxe5 Rgf6

Position after 39...Rgf6

40. Rxg7+! Nasty.  At least I saw this one on the last move of the time control. White wins now.

40…Kxg7 41. Nd7 The black bishop “sight” to d7 was blocked by the pawn on g4.

41…gxf3 42. Nxf6 Kg6 43. Kf2 1-0

It was very strange how the two behind the scenes combinations that occurred in the analysis both involved the star move Bxe5!!.

Stay tuned, I will post Rounds 2, 4, 5, and 7.

Round 2

FM E. Yanayt – M. Ginsburg

To prepare for my half-point bye in round 3, I had this virtually unplayed game in Round 2.

1. d4 Nf6 2. c4 e6 3. g3 Bb4+ The best winning attempt here is 3…c5.

4. Bd2 Bxd2+ 5. Qxd2 d5 6. Nf3 Qe7 7. Bg2 O-O Somehow 7…Ne4 and then the Qe7-b4+  follow-up didn’t look very impressive.

8. O-O Rd8!

I have seen this line a lot (I was always white) in ICC blitz versus eastern-bloc GM’s.  It’s a very solid system.

9. Qc2 c5 10. cxd5 cxd4 11. Nxd4 Na6!? Seems good, with the idea to pop into b4.  The game is about even.

1/2 – 1/2

Round 3

During my bye-round, the following reversal of fortune occurred.

D. Naroditsky – GM S. Kidambi (2616)

Black may have been hexed in this game due to the fact I have never heard of him although he has a high rating.

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Nf3 Ngf6 6.Nxf6 Nxf6 7.Bc4 Bf5 8.O-O e6 9.c3 Bd6 10.Qe2 Qc7 11.h3 O-O 12.Nh4 c5 13.Nxf5 exf5 14.Bd3 g6 15.Bg5 Rfe8 16.Qd2 Ne4 17.Bxe4 fxe4 18.dxc5 Bxc5 19.Rad1 Re6 20.Be3 Rd6 21.Qe2 Bxe3 22.fxe3 Rad8 23.Rd4 Rxd4 24.cxd4 f5 25.Qd2 Rc8 26.Qb4 b6 27.Qb3 Kg7 28.Qe6 Rf8 29.Kh1 Rf6 30.Qe8 Rc6 31.d5 Rc2 32.Rd1 Qg3

This obvious move places white into an unbreakable zugzwang and it is hard to fathom that black did not win, much less lost.

33.Qe7 Kh6 34.Qf8 Kh5 35.Rg1 Rd2 36.Qf7 h6 37.b4

Black to play and avoid winning

Black is completely winning.  But, I am guessing he had not much time left.  Even so, what follows is a complete botchery.

37…Rxa2? Why? 37…a5 preserves the zugzwang situation.   The even simpler solution 37…Qxe3 was also completely winning.  White cannot make any threats.

38.d6 Rd2 39.d7 Qd6? Time-trouble? It was safe to play 39…Qxe3 and black should win.

40.Rf1? Maybe mutual time-trouble. 40. Qg7 was equal.  The text aims for a cheapo but should lose.

40…Qxd7?? OK probably time-trouble.  I was drinking and gambling at the Bellaggio and didn’t witness this debacle. 40…Kg5! eliminates all cheapoes and wins easily.

41.Rxf5+ Oops.  White wins.  Black must have felt sick, given he had iron-clad zugzwang a few moves ago.

41…Qxf5 42.g4+ How embarrassing.  Black totters on a few moves.

42…Kh4 43.gxf5 Kxh3 44.Qxg6 Rd1 45.Qg1 Rxg1 46.Kxg1 a5 47.bxa5 bxa5 48.f6 1-0

Round 4

M. Ginsburg – H. Liou  Dutch NIC SOS Special

1. d4 f5 2. Qd3 I saw this in a New in Chess “SOS” supplement; the game in question occurred in the “B” section of the German Bundesliga.

2…d6 As the NIC states, Leningrad players are reluctant to play the strongest move in the position, 2….d5.   Now, white gains enormous white square pressure with the game sequence.

3. g4 fxg4 4. h3 Nf6 5. hxg4 Bxg4 6. Bg5! Be6 This unhealthy retreat signals black already has problems.  White was threatening the crude Bxf6 and Qe4.

7. Nc3 c6 8. Bxf6 gxf6 I would prefer 8…exf6 to try to keep white’s plus to manageable proportions.

9. Rxh7 Rxh7 10. Qxh7 Qa5 11. Bh3 Bf7 12. O-O-O Na6 13. d5! This move cutoffs black’s queen from the kingside for the time being.

13…cxd5 14. Nf3 d4  15. Nxd4 Qh5 16. Qd3 Nb4 17. Qb5+ The smoke clears and white is left with a huge advantage due to light square control.  How many Dutch games have been lost due to black not being able to observe the squares he weakened on move 1?  I recommend readers get the tournament book San Antonio 1972 and read Petrosian’s comments to Petrosian-Larsen.

17…Qxb5 18. Ncxb5 Kd8 19. Ne6+ Bxe6 20. Bxe6 Black is now totally paralyzed.

20…a6 21. Nc3 Bh6+? Making matters worse, but it was very bad anyway.  The ill-fated bishop gets trapped shortly.

22. e3 Kc7 23. a3 Nc6 24. Nd5+ Kb8 25. Nb6 A complete rout. I would resign as black now.

25…Ra7 26. Rh1 Nd8 27. Bb3 Bg5 28. f4 Kc7 29. fxg5 fxg5 30. Rh8 e6 31. Nc4 d5 32. Rh7+ Kc6 33. Ne5+ Kd6 34. Nf7+ Nxf7 35. Rxf7 Ke5 36. Kd2 Ra8 37. Rg7 Kf6 38. Rxb7 g4 39. Ke2 Kg5 40. e4 Rd8 41. exd5 exd5 42. Ke3 Re8+ 43. Kd4 g3 44. Bxd5 Kf6 45. Rb3 1-0

Round 5

I could not overcome the solid Hungarian I. Somogyi!

I. Somogyi – M. Ginsburg  King’s Indian g3 line

1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. g3 O-O 5. Bg2 d6 6. Nf3 c6
7. O-O Bf5
As successfully played in Schroer-Benjamin, USCL 2009.  White in my game plays more strongly.

8. Nh4! Be6 9. d5! Bd7 10. e4 Na6 11. h3 cxd5 12. cxd5 Nc5 13. Be3 Qa5
14. Rb1 Na4!
Keeping the balance.

15. Nxa4 Bxa4 16. b3 Bb5 17. Re1 Qa3 18. Qd2 Rac8 19. Bd4 Nd7 20.
Bxg7 Kxg7 21. Nf3 Ne5!
Still equal.

22. Nxe5

Black survives the dangerous attempt 22. Nd4!? Ba6 23. Qg5!? Rce8! (23…Rc7 is all right is black is careful: 24. Nf5+ Kh8 25. Nxe7 f6 26. Qh6 Rf7? 27. Rbc1! wins nicely – I saw that during the game; but 26…Re8 holds) 26…24. Nf5+ Kh8 25. Nxe7 f6 26. Qh6 Rf7 27. f4 Rfxe7 28. fxe5 fxe5)

22… dxe5 23. Rbc1 f6 24. h4 Bd7 25. Kh2 Qd6 26. Rxc8 Rxc8 27. Rc1 e6? Careless.  Correct is 27… Rxc1! 28. Qxc1 e6 =

28. Rxc8 Bxc8 29. Qc3? 29. Bh3! sets a great trap.  If 29…Bd7? (correct is 29… b6! 30. Qd3 Qc5 31. Kg2 exd5 32. Bxc8 Qxc8 33. exd5 Kf7 34. h5 =) 30. Qa5! and black has big problems.  If 30… exd5? (30… Qb6 31. Qxb6 axb6 32. dxe6 Bc6 33. f3 Kf8 34. Kg1 Ke7 35. Kf2 is very good for white as black cannot round up the e6 pawn) 31. Qd8 suddenly wins!

29… Bd7 30. dxe6 Bxe6 31. Bh3 Bf7 32. Bf1 Be6 33. Bh3 1/2-1/2

Round 6

Interestingly, in othe Round 6 action, Friedel played what appeared to many to be a ludicrous variation of the 2 Knights – but it worked and his opponent, NM Zierk, blundered and lost.  I have posted elsewhere on this opening (2 Knights “Ulvestad”); it looks very bad for black and I think its days are numbered.

M. Ginsburg – FM J. Dean          Main line Tarrasch Defense

1. Nf3 d5 2. c4 e6 3. g3 Nf6 4. Bg2 Be7 5. O-O c5 6. cxd5 exd5 7. d4 Nc6 8. Nc3 O-O 9. Bg5 cxd4 10. Nxd4 h6 11. Be3 Re8 12. Qb3!

GM Portisch Special

GM Lajos Portisch’s excellent treatment, I believe covered in one of Kasparov’s My Great Predecessors volumes.  When the Queen is chased by the knight, the knight winds up not having a happy home.  Similarly, if the black knight on f6 chases the B/e3, it also does not have a happy home after the bishop moves away.

12…Na5 13. Qc2 Nc4 14. Bf4 White looks better here.  The Black knight on c4 is very unstable and that is one of the my points of 12. Qb3.

14…Be6 15. Rad1 Qc8 Black has problems.  The most normal move, 15… Rc8 16. Nxe6 fxe6 17. Qg6 Kh8 18. b3! Nd6 19. Be5 leaves white with a simple plus.

16. Nxe6 fxe6 17. e4? A big lemon! It’s always right to kick the advanced knight with 17. b3! (obvious) 17… Nd6 18. Rc1 Rf8 19. Qd3 Qe8 20. Rfd1 Rc8 21. e4 Ndxe4 22. Nxe4 dxe4 23. Bxe4 and white is much better.

17… e5! This move completely escaped my attention.  White is still better, but not as much.
18. Bc1 d4 19. Nd5 Nd6 20. Qd3? Another significant inaccuracy.  20. Qb3!   Nc4 and only NOW 21. Qd3 leaves white with a plus.

20… Nxd5 21. exd5 Bf6! I totally bothced it. Black is fine.  The center pawns are mobile.  Black’s only problem is a severe lack of time.

22. Qg6? Practically speaking with black having less time, white should play 22. Rfe1 Qd7 23. Bd2 Rac8  but of course Black is all right.

22… Qf5! 23. Qxf5 Nxf5 24. Be4 Nd6 25. Bg6 Re7 26. Rfe1 e4?? Any reasonable queen rook move is equal.  Unfortunately, black was in severe time trouble already. This move loses a pawn and the game.

27. Bf4 Be5 27…Rd8 28. Bxd6 loses for black in the long run.  Although there are bishops of opposite colors, too much material remains.  It’s similar to Yermolinsky-Naroditsky North American Open 2009 except there white fell into a last-ditch stalemate trick and Naroditsky saved it!

28. Bxe5 Rxe5 29. Rxd4 Rd8 30. Bxe4 Nxe4 31. Rexe4 Black has no chances in the single rook ending.

31…Rxe4 32. Rxe4 Rxd5 33. Re7 Rb5 34. b3 a5 35. Kg2 a4 36. bxa4 Rb4 37. a5 Rb5 38. Re8+ Kh7 39. Ra8 Rb2 40. a6 Black resigned.


The move 40. a4! also wins: 40…Ra2 41. a6 b6 42. Rb8 Rxa4 43. Rxb6 and wins.

In the game, black can try a last-gasp 40… b5! move.  Suggested by Siddharth Ravichandran (rating=2489) after the game as drawing – and indeed this is a great try!

40...b5! - Suggested by kibitzer Ravichandran

There is only a study-like refutation: 41. a4!! – only after he suggested 40…b5 (which I did not see in the game) did I notice this move which is a nice interference theme, and white wins.

Position after 41. a4!! - nice interference theme. (analysis)

Also in Round 6, this amusing error-fest:

Zierk – Friedel   2 Knights, Refuted Silly Ulvestad Line

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 I would pay more attention to Karpov’s legendary logic here and try 3…Bc5.

4.Ng5 d5 5.exd5 b5(?) Very illogical!  Good in the 1800s, maybe.

6.Bf1 h6 (might as well, 6…Nd4 leads to a bad game too)  7.Nf3?

I don’t want to be a wet blanket, but the fairly obvious 7. Nxf7! results in a big edge for white. This was shown in other examples recently.  At least black is not playing the refuted mainline with 6…Nd4.

7…Qxd5 8.Nc3 Qe6 9.Bxb5 Bb7 10.O-O O-O-O 11.Re1 Bc5 12.Qe2 Nd4 13.Nxd4 Bxd4 14.Nd1 Nd5 15.Bc4 Qg6 16.Bxd5 Bxd5 17.Ne3 Bxe3 18.fxe3 Qxc2 19.d4 Qe4 20.b3 Rhe8 21.Bb2 Re6 22.Qd2 Bb7 23.Rac1 Rdd6 24.Rf1 Rf6 25.Rfe1 Rc6 26.dxe5 Rxc1 27.Bxc1 Rg6 28.Re2 Rc6 29.e6 Rxe6 30.Qc2 Rc6 31.Qb2 Qd3 32.Rf2 Ba6 33.Bd2 Rc2 34.Qd4 Rxd2 0-1

Round 7

Lev Milman – M. Ginsburg  Sicilian Scheveningen

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. Be2 Be7 7. Be3 O-O 8.
O-O Nc6 9. f4 Bd7
A rare sideline.

10. Qe1 Conventional thinking has 10. Nb3, avoiding exchanges, as white’s best bet.

10…Nxd4 11. Bxd4 Bc6 12. Qg3 g6 13. Qe3 Qa5 Black is threatening  is all right.

14. e5 dxe5 15. fxe5 Nd5 16. Nxd5 Qxd5 17. Bf3 Qc4? 17… Qb5 is more accurate. 18. a4 Qb4 19. Bxc6 bxc6 20. b3 c5 21. Bc3 Qb7 and black has equal chances.

18. b3 Qa6 19. c4 Qa3 20. Kh1 Kg7 21. Rf2 21. Bxc6 bxc6 22. Qe4! places black in a passive situation.

21… h6 Here, best was 21… a5! with equal chances.

22. Bxc6 bxc6 23. Raf1 Rad8? With a draw offer.  But this move is a blunder.

24. g3? A blunder in return.   Surprisingly, white can take.  24. Bxa7! c5 25. Bb6 Rd7 and now the amazing resource 26. Rf3 Rb7 27. Qf2!! and wins.  The f7-point collapses.

24… Bg5 25. Qe4 h5 26. Bc3?! White can preserve something with 26. Rf3 Rd7 (26… Qxa2?? 27. Bc5! winning) 27. Bg1)

26… Qc5 27. b4 Qe3! Judging from white’s reaction, he might have missed this.

28. Qxe3 Bxe3 29. Rf3 Bd4 30. b5! With a draw offer.

When I made my 29th move, I thought black was much better because of the white weak pawns.  However, white’s 30th generates plenty of activity and it’s in fact equal!

For example, 30…Bxc3 (30… cxb5 31. cxb5 Rd5 32. Bb4!) 31. Rxc3 cxb5 (31… Rc8 32. a4) 32. cxb5 Rd5 33. a4 Rd4 34. Rf4! =.

1/2 – 1/2

Tournament Postscript – The Cheater’s Clock Gambit

For completeness, here is amusing cheating I heard about in the skittles room.  In a lower section, someone had 28 minutes left versus 28 seconds left in sudden death in a complicated position.  The person with 28 seconds left simply pressed the clock without making a move.  Rattled, the person with 28 minutes left upon returning to the board assumed the guy with 28 seconds left had made some kind of move and made a move in return.  The guy with 28 seconds left then called the TD and said “I get 2 more minutes on my clock because he made 2 moves in a row.”  In the absence of witnesses, the TD upheld this ludicrous “gambit”.  The guy with 28 seconds left got 2 more minutes on his clock and that was enough for him to win the game.  This kind of stuff can only happen in American Swisses.  Why is that?   Well, that’s not strictly true.  After all,  a many time US Champion did exactly the same thing in a US Championship round-robin invitational. But we won’t get into that.


The Fabulous 00s: USCL Week 3 OOTW

September 18, 2009

2009 USCL Opening of the Week – Round 3

IM Jonathan Schroer – GM Joel Benjamin King’s Indian Defense

Two stalwart denizens of the 1980’s Manhattan Chess Club (located at the world-famous Carnegie Hall) go at it in 2009-style online combat.

1.d4  Nf6  2.c4  g6  3.Nf3  Bg7  4.g3  0-0  5.Bg2  d6  6.0-0  c6  7.Nc3  Bf5!?

Not Incredibly Strong but Not Stupid

Not Incredibly Strong but Not Stupid

There’s something positionally appealing about setting up a d6,c6 pawn chain, getting this bishop out, and preparing a later d5.  In a related setup, black can try Nc6 (instead of c6) and then B to g4.  Then his idea is hit in the center with e7-e5 after the N on f3 is diverted or traded.

For example, Ron Henley – MG Lone Pine 1980 went

1. d4 Nf6 2. Nf3 g6 3. g3 Bg7 4. Bg2 O-O 5. O-O d6 6. c4 Nc6 7. Nc3 Bg4!? Unusual but interesting.  I can recommend this for further research to KID explorers out there.

8. Ne1 Qc8 9. b3 e5 10. d5 Ne7?

Here I go wrong and go ‘passive’.  The bubbly 10… Nd4! is correct with level chances. For example, 11. f3 Bh3 12. e3 Bxg2 13. Kxg2 Nf5 14. Nc2 c5! and black is fine.

11. f3 Bh3 12. e4 Bxg2 13. Kxg2. White has a definite pull now and I was lucky to draw.

Let’s return to the diagram position.  What should white do?  This is the key theoretical moment.

8.b3?! White is giving too much respect to black’s offbeat idea.  Our first guess based on prior evidence is that 8. Ne1! is correct. It accomplishes several aims.  Mostly, it aims to establish a white square pawn chain and induce black to trade B/f5 for B/g2. Secondly, it prevents Nf6-e4 which is strong in the game!

Let’s look at 8. Ne1! more closely.  We only give it an exclam here due to its success statistically in ChessBase prior games. As we shall see, this may be misguided.

After the possible followup 8…Qc8!? 9. e4 Bh3 10. f3 Bxg2 11. Kxg2 we reach another critical moment.  In practice, white has been scoring very highly here with his space advantage.  However, a single database game stands out for an interesting black response:

11. … c5! An amazing two-step with the black c-pawn.  It makes sense!  Rather than wait passively for a white build-up, black takes action to clarify the structure.  On the other hand, WEAK is 11…e5? 12. dxe5 dxe5 13. Be3! with a pleasant exchange-KID style safe edge for white, who has gotten rid of his problem child light squared bishop!  (Don’t remind Bruci Lopez about Exchange KIDs after he lost to Jesse Kraai in Weak 3 action, apparently an Altounian “special” delayed exchange variation because white cannot lose.  And who, after all, wouldn’t mind a KID where white cannot lose!).

Let’s see this ingenious 11…c5!.


Position after 11…c5!

12. dxc5 Qxc5 and black is OK; or

12. d5 Nbd7 (in Amann-Martinovic, Austria 1998, the weaker 12…Na6 was played but black still drew) 13. Nc2 a6 and black has an acceptable Benoni with level chances.  12…Nh5 is also playable.

Well, let’s see, we might have to re-think and go back.  Maybe 8. Ne1 is not so fearsome!  What else?  8. Nh4 has been tried by such luminaries as Karpov and Portisch but that’s not dangerous; the WN is offside there.  8. Qb3!? is another try which has some logic, after all black’s Bf5 unguarded b7.  After 8. Qb3!? Qb6 9. Re1!? (Wojo used to try this)

A Wojo Special

A Wojo Special

White emerges with a small edge after the optically scary 9…Qxb3(?!) 10. axb3 Bc2 11. b4 Na6 12. b5 Nb4 13. e4!.  Wojo was a big openings expert so it makes sense to focus further research on his idea.  Even so, black doesn’t have to take, and can play e.g. 9…Na6.  His position looks fine.

Conclusion:  there’s no clear path for a white advantage in this KID sideline!

Returning to the game, recall that Schroer has reacted cautiously and rather passively with 8. b3.  This permits…

8… Ne4! Black is completely OK already; an opening success. In subsequent play Schroer vacillated between “solid” and “aggressive” with predictable results.

9.Bb2  Nxc3  10.Bxc3  Be4  11.Qd2  e6  12.Qe3  d5  13.Bh3  Bxf3  14.Qxf3  f5  15.Qd3  Nd7  16.f3  a5  17.Kh1  Qg5  18.Bg2  Qh5  19.Qe3  Rfe8  20.Qd3  Nf6  21.e4  dxe4  22.fxe4  Rad8  23.Rad1  c5  24.Bf3  fxe4  25.Bxe4  Ng4  26.Qe2  Rf8  27.Bf3  Rxf3  28.Rxf3  Nxh2  29.Kg2?

This has nothing to do with the opening, but the inhuman machine finds a way for white to get a half point here. 29. Qxe6+! Kh8 30. Rf7!! Qxd1+ 31. Kxh2 cxd4 (31…Qc2+ 33. Kh3 Qxc3 34. Rxg7! and draws) 32. Bxa5 Qh5+ 33. Kg1 Qxa5 34. Qe7 Rg8 35. Rxg7! with a draw!  What a line!

29…Qxf3+  30.Qxf3  Nxf3  31.Kxf3  b6  32.Ke4  cxd4  33.Rd3  e5  34.c5  bxc5  35.Bxa5  Ra8  36.Bb6  Rxa2  37.Bxc5  Re2+  38.Kf3  Re1  39.Kf2  Rc1  40.b4  e4  41.Ra3  e3+  42.Ke2  Rc2+  43.Ke1  Be5  44.Ra8+  Kf7  45.Rf8+  Ke6  46.Re8+  Kd5  White resigns 0-1
