The Fabulous 00s: USCL Week 7 Opening of the Week (OOTW)

October 19, 2009

Let’s explore an interesting junior battle.

Gerald Larson (TEN) – Trevor Magness (CHI)  USCL Week 7

Ruy Lopez Exchange

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.0-0 Bg4 6.h3 (?!)

Let’s try NOT doing h3 yet (this committal move gives black a ready-made lever on the kingside).  I’m going to recommend here 6. d3!? Qf6 7. Nbd2 O-O-O 8. a4!? awaiting events.  For example, 8. a4 g5 9. h3 Bh5 10. Qe2! Kb8 11. g4! Bg6 12. Nc4! and white has an edge.  Delaying h2-h3 looks foxier. It also probably has the advantage of taking black out of the well-known channels.

6…h5! Of course! Known to be bad for white now is 7. hxg4 hxg4.

I enjoy junior games.  There will always be the sharpest twist on the most innocuous starting positions.  No theoretical verdict has been reached on this line.  Let’s see what happened…

7.d3 Qf6 8.Nbd2 Ne7 9.Re1 Ng6 White is fairly tied up now due to the pressure on f3.  His next move alters the structure but he could also eat on g4 at this moment.

Key Moment

10.d4

After the only optically risky 10. hxg4!? hxg4 11. Nh2? Bc5! black had a big edge and won in Fressinet-Kazhgaleyev, Paris 1996.  Correct is 11. g3! and white holds after some adventure: 11. g3! Bc5 12. Nb3! Bb6 (Looks terrible for white, doesn’t it?  But… white escapes!) 13. Bg5 Qxf3 14. Qxf3 gxf3 15. Nd2 f6 16. Be3 Ba5! 17. c3 O-O-O 18. Rad1!! Rxd3 19. Nc4! and draws!

10…Nf4 11.dxe5

I guess it’s too much to ask for the nice trap 11. hxg4 hxg4 12. Nh2 Nxg2!! winning, as has occurred in a bunch of games.

11…Qg6! 12.Nh4! The only way to hold the balance!  Still, black can and should have posed problems before white reaches safety.

12…Bxd1 13.Nxg6 Nxg6 14.Rxd1 0-0-0 15.e6 fxe6 The foxy 15…f6!? is perfectly possible but it’s still equal.  15…f6!? has the virtue of keeping things relatively speaking more complicated.

16.Re1 Bb4?! 16…Ne5! sets practical problems and black has the easier time of it.  The text forces white to make a useful move.  Anyway, we’re far afield of the opening now — black’s setup passed the theoretical test!

17.c3 Bc5 18.Nb3 Bb6 19.Be3 Rd3 20.Bxb6 cxb6 21.Rad1 Rhd8 22.Rxd3 Rxd3 23.g3 Kd7 24.Kf1 Ke7 25.Ke2 Rd8 26.Rd1 Rxd1 27.Kxd1 Ne5 28.Nc1 Nf7 29.h4 Kd6 30.Ke2 c5 31.Nd3 g5 32.hxg5 Nxg5 33.f3 Nh7 34.e5+ Kd5 35.Ke3 b5 36.Kf4 a5 37.Nf2 a4 38.Ne4 Kc4 39.Ke3 b4 40.Nd6+ Kd5 41.f4 b6 42.c4+ Kc6 43.Ke4 Kd7 44.Kd3 Nf8 45.Ne4 Ke7 46.Nf6 h4 47.gxh4 Ng6 48.h5 Nxf4+ 49.Ke4 Ne2 50.h6 Kf7 51.Nd7 Nc3+ 52.Kd3 Nxa2 53.Nxb6 a3 54.bxa3 bxa3 55.Nd7 Nb4+ 56.Kc3 a2 57.Kb2 Kg6 58.Nxc5 Kxh6 59.Nxe6 Nd3+ 60.Kxa2 Nxe5 61.c5 Kg6 62.Kb3 Kf6 63.Nd4 Ke7 64.Ka4 Kd7 65.Kb5 Kc7 66.Ne6+ Kb7 67.Nf4 Kc7 Game drawn by mutual agreement 1/2-1/2

The Fabulous 00s: Strong Chess on your Phone!

April 2, 2009

On your iPhone more particularly – Glaurung and Shredder!

Glaurung is a very strong and free program available from the iPhone “Apps Store.”  I will post some Glaurung games that I contested on my iPhone 3g – it lets you save the games on the phone as PGN!  What progress in the field of computer chess – a program in excess of 2500 USCF strength running on a slim svelte iPhone – I am very impressed!   It allows “takebacks” so hapless humans can takeback many times…. and still not win.   One of the nice features is that when the human taps on the piece to move, the computer draws blue dots on the screen of all that piece’s legal move destinations.  Then the human just taps on one of the blue dots.  The iPhone relies on human finger tapping, not a Treo-style stylus.

“flyer” on ICC also alerted me to Shredder on the iPhone:  “Shredder for iPhone is available now…it rates your play, has a million-move opening book, and 1,000 exercises…though I’m not sure how strong it is :-)”

Here Comes Technology

Oh some chess?  A Snappy Caro-Kann Gamelet

The point of this site (besides robot cartoons) is chess (and nominally, chess history). I like the word ‘gamelet’.  It was used a lot in Reinfeld and Chernev books.  Here’s an ICC blitz gamelet

[Event “ICC blitz”]
[Site “cyberverse”]
[Date “2009.04.14”]
[White “aries2”]
[Black “chessIPO1”]
[Result “1-0”]
[ECO “B18”]

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Bf5 5. Ng3 Bg6 6. h4 h6 7. N1e2!? A great blitz weapon.

7…e6 8. Nf4 Bh7 9. Bc4 Nf6 10. Qe2 Nd5 11. c3

 11…Be7? A weak move that gives white the g7 point to attack.  An interesting try is 11… Qd6!? that wound up as a draw in two example database games.

On the other hand, 11… Nxf4?! 12. Bxf4 Bd6 13. Qg4 Bxf4 14. Qxg7 Ke7 15. Nh5! is bad for black and white duly won, 1-0 Rubinetti,J-Benko,F/Buenos Aires 1965.

12. Ngh5! O-O?! Another misstep.  Correct is the cold-blooded 12… Rg8! and now, for example, 13. O-O!? Bxh4! 14. Re1 Be7 15. Qe5 Kf8 16. Nxe6+ fxe6 17. Nf4 Bf5 18. Nxe6+ Bxe6 19. Qxe6 Qd7 20. Qe4 Na6 21. Qf3+ and now the computer indicates a fantastic defense resource: 21…Bf6! 22. Bxh6 Rh8 23. Bd2 Kg8! and black holds.

13. Qg4 I did not consider (but should have) the tricky 13. Bxd5!? exd5! (13… cxd5? 14. Nxg7! Kxg7 15. Qe5+ f6 (15… Kg8 16. Nh5 f6 17. Qg3+ forces resignation) 16. Nxe6+ Kh8 17. Qg3 Rg8 18. Nxd8 Rxg3 19. fxg3 Bxd8 20. Bxh6 with a big ending edge) 14. Qe5 f6! (14… Bf6? 15. Nxf6+ Qxf6 16. Qxf6 gxf6 17. Rh3 is horrible for black) 15. Qe3 Qe8 and black holds on; hard-to-see defense!

13… Bf6 14. Nxg7! A standard, but aesthetic, blow.  With colors reversed, Beliavsky once landed this tactic against ex-WC Karpov on the g2 square in a stodgy QGD and won as black! I recommend that the readers consult the excellent book “Uncompromising Chess” by Beliavsky to improve their game.

14…Bxg7 15. Nh5 Bg6 16. Nxg7 Kxg7 17. h5 Nf6

Position after 17…Nf6.  An interesting moment. 

18. Bxh6+?! I didn’t consider the very strong 18. Qg3! Ne4 (18… Rh8 19. hxg6 fxg6 20. Bf4 Nbd7 21. Bd3 Qe8 22. O-O-O and white wins) 19. Qe5+ Qf6 20. Bxh6+ Kxh6 21. hxg6+ Kg7 22. Rh7+ Kg8 23. Qxe4 Qxg6 24. Qxg6+ fxg6 25. Rxb7 and it’s all over.  The text allows black a surprising way to wriggle out to near-equality.

18… Kxh6 19. hxg6+ Kg7 20. Qg5!  White can go wrong with the unsound 20. Rh7+??  Nxh7 21. gxh7+ Kh8! and white can resign.

Position after 20. Qg5! —  Decision time.

20… fxg6? 20… Rh8!! is a great defense. 21. gxf7+ Kxf7 22. O-O-O Na6 (just getting stuff out) 23.
Qe5 Nd5! (23… Qd7? 24. Rxh8 Rxh8 25. g4 with a big initiative) 24. Bxa6 bxa6 25. c4 Nb6 26. Rde1
Qf6 27. Qc7+ Qe7 28. Qxc6 Rac8 29. Qf3+ Qf6 30. Qxf6+ Kxf6 31. c5 Nd5 32. Kd2 and white can pretend to have a small edge here.

21. Rh6 Now white wins.

21…Qe8 22. Bd3 Nh7 23. Rxg6+ Kh8 24. Qh6 For some reason the stronger check, 24. Qe5+!, did not come to my mind.  After 24… Rf6 25. Rh6 white wins.  When I played this move, I had in mind the nice game continuation, but it’s not forced.

24… Qf7 25. Rf6! 1-0 A pleasing end to a pleasing gamelet.  Black is caught in a cross pin and resigns.

Final position after 25. Rf6!

What’s on the Horizon

We all know Ilya Nyzhnyk (up and coming 12 year old prodigy who needs a vowel).  Who’s after him?  Here are some more youthful Russian prodigies.

And To Conclude – Some Reader Queries

Some readers were asking, “is it true sushi is served sometimes with real gold leaf?”  Yes it is. For example, on Avenue A in New York City, “Le Miou”.

gold_sushi

That’s real gold leaf!  Nutritious?  Dunno, probably not.

Others were asking, “What’s the best looking motorcycle cruiser?”  I would vote for the Victory 8-ball.

Victory 8-ball.  Best Looking?
