Gavon 2 Chess Test Scores

Post by spacious_mind »

Since I wanted to concentrate on completing all the Gavon test scores first, I have not been able to test too many Gavon 2 yet.

GAVON 2

COLOR KEY

I am using this color key to help me to easily see the chess programs that I would include in any tournaments with dedicated chess computers and keep the challenge competitive. This is based on the top Tasc R30 or Chessmachine programs being entered as well.

GAVON 2 TEST SCORES

Gavon 2 has the same 46 chess programs as Gavon. I have only been able to test 9 of these programs so far. But two of the new programs, Ifrit v. J3.6 and Darky v. 0.5e not showing under Gavon's test results I have completed with Gavon 2.

As expected Stockfish 6.0 is the monster with a rating over 3000 ELO.

I got myself completely sidetracked yesterday. I wanted to start working on some more Gavon 2 tests when I got the urge to just play a quick game against Gavon 2. As I switched Gavon 2 on Protector 1.7 was in memory so I played it. I played white in this game, Protector played at Level AT30.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Be7 8. Qf3 Qc7 9. Bd3 Nbd7 10. Bh4 {Gavon 2 Protector 1.7 out of book}

[fen]r1b1k2r/1p1nbppp/pq1ppn2/8/4PP1B/1NNB1Q2/PPP3PP/R3K2R w KQkq - 0 11[/fen]

Gavon 2 Protector 1.7 was out of book in this typical Sicilian Najdorf after I played my Bishop back to h4, which is less typical but I often do this because rather than exchanging on f6, I like to keep it on the board and have the option to withdraw it to f2.

That's as far and beyond any theory I may know goes anyway, as I am at least 40 years behind modern opening theory. I had learned openings by pretty much memorizing the only two books I had. The first being Fisher's My 60 Memorable Games where I had memorized every single game and it's detailed variations and comments as an 11/12 year old.

It has it's drawback though because I pretty much became an exclusive K to e4 opening player. And it never really changed not even today as it became a kind of comfort zone to play Ke4 as white.

The second book I had was Botvinnik's 100 selected games. It was a library book that I found in the local town library. I never gave the book back :P after months and months of reminders, I eventually went to the library and told them I had lost it. So I ended up having to pay something like 50p (British) lost fee. (Hey don't knock me I was around 12 years old at the time :P ).

Actually there was another small book that I bought a little later, I think it was a Batsford book on Chess Openings written around 1969/70. I remember buying it well from Hudson's Bookstore in Birmingham, England and receiving crap from my friends for buying a chess book, as we had all decided to catch the 144 bus from Bromsgrove to Birmingham City Center on one Saturday morning to browse the stores and Birmingham Market for music vinyl's or modern clothes that our parents wouldn't buy for us, all to impress girls :). We kids back then all seemed to have jobs before school or after school which we did so that we had some money in our pockets. For me it was Newspaper delivery rounds, Milk Delivery rounds, pumping gas at a gas station or even picking things like strawberries, potatoes or peas at farms on weekends or summer holidays. We pretty much did anything to have a little pocket money. Officially by law you could do that from the age or 13, but no one really checked your age and you just had to lie and say you were 13 and look near enough 13 and there was no such thing as I.D. in England. So I was earning pocket money from about the age of 11 starting with Newspaper deliveries to peoples homes, so they could read them before they went to work. Most parents supported and were proud of their kids back then if they had the wherewithal to earn some pocket money. People weren't rich and things just weren't as complicated as they are today.

My parents however being both Yugoslav never really approved of me playing chess, they knew I was good at it and that I was representing the high school team (as a US equivalent of a Freshman) as well as playing and representing the city's Chess Club team in matches. From where they came from in Yugoslavia, chess was often played by bums who gambled on it to make a few cents. Therefore they were always suspicious and thought it would ruin me. In fact, I remember getting caught on occasions in the middle of the night around 2 am or something by my father who would get up to use the bathroom and see that my lights were still on in my bedroom and he'd get mad knowing that in a couple of hours I would slip out and do the paper round or milk round before school. And, I'd get a cussing for not spending that same amount of time to do school homework.

Thinking back it was funny really because if Ali fought, or when we had the soccer World Cup in Mexico 1970 or Olympic games, we would wake each other up so that we could watch the Broadcast Live before work or school. :P

Anyway enough reminiscing and sidetracking, they were great times though..

Qb6 11. Nb3 Nxe4 12. Bxe7 Nxc3

[fen]r1b1k2r/1p1nBppp/pq1pp3/8/5P2/1NnB1Q2/PPP3PP/R3K2R w KQkq - 0 13[/fen]

Here I was in a dilemma, because I could have taken the e-pawn with the Bishop but would have ended up with doubled pawns in front of my king. So I decided to withdraw the Bishop back to H4 instead. As compensation for the pawn I felt that my position had all sorts of possibilities for making life hard for Black's king.

13. Bh4 Nd5 14. O-O-O Qc7 15. Kb1 b5 16. Be4 Rb8

[fen]1rb1k2r/2qn1ppp/p2pp3/1p1n4/4BP1B/1N3Q2/PPP3PP/1K1R3R w k - 0 17[/fen]

The above position was the point of this post. I just don't understand how Gavon Protector 1.7 which is rated extremely high (3020 ELO at CCRL 40/40) missed playing 16. ... Bb7! as the move played is terrible and loses straightaway. I went back and double checked its settings to make sure it was playing max strength and not some reduced strength and everything checked out. I think at level AT30 (30seconds per move) Protector 1.7 surely had so see 16. ... Rb8 loses??

17. Bxd5 O-O 18. Be4 f5 19. Bd3 Bb7 20. Qh3 g6 21. Rhg1 Bd5 22. g4 fxg4 23. Rxg4 Nf6

[fen]1r3rk1/2q4p/p2ppnp1/1p1b4/5PRB/1N1B3Q/PPP4P/1K1R4 w - - 0 24[/fen]

In this position I just couldn't resist returning my piece advantage by sacrificing my Rook with 24. Rxg6

24. Rxg6+ hxg6 25. Rg1 Nh7 26. Rxg6+ Kh8 27. Bf6+ Rxf6 28. Rxf6 Bxb3 29. Rh6 Rg8 30.
Rxh7+ 1-0

Final Position

[fen]6rk/2q4R/p2pp3/1p6/5P2/1b1B3Q/PPP4P/1K6 w - - 0 30[/fen]

After the game I went back to this position:

[fen]r3k2r/1bqn1ppp/p2pp3/1p1n4/4BP1B/1N3Q2/PPP3PP/1K1R3R w kq - 0 17[/fen]

Where instead of playing the losing move 16. ... Rb8 I wanted to see what would have happened after 16. ... Bb7

From this position I still would have taken the Knight with 17. Bxd5 which would have been followed by 17. ... Bxd5

[fen]r3k2r/2qn1ppp/p2pp3/1p1b4/5P1B/1N3Q2/PPP3PP/1K1R3R w kq - 0 18[/fen]

And from the above position I would have exchanged my rook for the Bishop with 18. Rxd5.

It is the above position that used up my day yesterday. I spent hours seeing if I could win this as White. I don't think you can but Black's position is so uncomfortable that I don't think that I would hesitate to play it and see what comes out of if it ever arises again.

It's the hours I spent with this position yesterday that made me smile as I remembered by father giving me crap as kid for doing the same that made me want to share this post. Hope you all don't mind.

As for Gavon 2 Protector 1.7's blunder. I have no idea why it wouldn't see the obvious.

Hey Nick

i liked the way you paused the game at just the right moment to share your childhood memories
you had the readers attention at that exact moment
good dramatic effect
interesting game and an even more interesting recollection

now..with all that aside .. i am not surprised that Gavon blundered at move 17.and went on to lose to you
i always was wary of this newfangled gadget

Teasing Regards
Steve

Thanks for the excellent post Nick. I enjoyed your ratings and comments about Gavon2, your game against Protector 1.7 (would it find the better move with more time? just wondering what would cause it to miss the better move), and especially your comments about your early years.

Entertained regards,
Dave

Hi Dave,

Thanks, that's the problem it doesn't repeat the error. I have tried to set up the position repeatedly and it will either play Bb7 or 0-0. I don't know if it was just an error of the moment when you reach that position in a game or if it remembers bad positions to never play the bad move again.

Kind of diminishes my what is probably a once in a lifetime success against it, but then again when it comes down to it, there really is not that much satisfaction in a win against someone who is much better than you anyway if the win was as a result of some incredibly stupid error. :? In any case analyzing the position was worth it. With my opening limitations this kind of position will come up again in games against computers and I will be more prepared for opportunities to smash them :)

Win or die gloriously... regards
Nick

Just one addition to the Gavon 2 tests with Faile v.1.4 written by Adrien Regimbald. It finished with a score ELO 2420. I updated the Gavon 2 table to include Faile v. 1.4

GAVON 2 TEST RESULTS

Josu keeps adding new chess programs to Gavon. The following new ones are included in his latest update:

Minko v. 3 by Borko Boskovic
Hakkapeliitta v. 3 by Mikko Aarnos
Clubfoot v. 1.0 by Shawn Chidester
Bitfoot v. 1.0 by Shawn Chidester
Umko v. 1.1 by Borko Boskovic
Cassandre v. 0.26 developped by Jean-François Romang, Raphaël Grundrich and Thomas Adolph, under the supervision of professor Jerzy J. Korczak.

That makes it now a total of 53 chess programs.

I also played a quick test match between Faile v. 1.4 against Revelation London. London had scored ELO 2240 in the test.

[Event "Computer Chess Match"]
[Site "Pelham, Alabama"]
[Date "2015.09.27"]
[Round "?"]
[White "Revelation London, LV 30S."]
[Black "Gavon 2 Faile v. 1.4, LV AT30."]
[Result "1/2-1/2"]
[ECO "B22"]
[WhiteElo "2240"]
[BlackElo "2422"]
[PlyCount "151"]
[EventDate "2015.09.27"]
[EventCountry "USA"]

47. Rc6 Bg7 48. Rc8+ Kh7 49. Rc7 Rf2 50. Ke6 Rb3 51. Rd3 Rb8 52. a6 Ra2 53. a7 Re8+ 54. Kf7 Ra8 55. Rdd7 Ra6 56. Bb4 h5 57. gxh5 gxh5 58. Bd6 Kh6 59. Bc5 f5 60. Bd6 Bh8 61. Be7 Kh7 62.

Faile v. 1.4 had the initiative in the early part of the game. Revelation London however took the initiative and may have won the game. But the position was very difficult so in the end the game was drawn.

[fen]3r4/PR3K1k/r6b/7R/3Bp3/8/8/8 w - - 0 68[/fen]

In the above position Revelation London played 68. Bg7. Evaluations however show +7.15 for London for the move 68. Bb6! There were several such rating jumps missed in this game.

As a result Gavon Faile v. 1.4 is shaded blue meaning it is a good opponent for dedicated programs.
