200 Games conducted in October


The test was conducted using Fritz 11 GUI on Windows 7 64-bit. The hardware is an AMD Phenom II 940 overclocked to 3.6 GHz.

Both engines used the same book renamed to bookone.ctg (Rybka 3) and booktwo.ctg (RobboLito 0.085c2). The book has no marked/priority moves. The book settings are 2/12 with learning mode disabled. The variety of play was set at approximately 71.4% which is 20/28 right arrow key.

The engines were 1 CPU 64 bit versions with hash size set to 256 MB and pondering/permanent brain was enabled.
Time control is 4 minutes with no increment.

100 games where Rybka used contempt setting of zero.

Code: Select all

1. RobboLito  +25/=58/-17	54.00%		54.0/100
2. Rybka  3   +17/=58/-25	46.00%		46.0/100
100 games where Rybka used contempt setting of 15 (default).

Code: Select all

1. Robbolito  +24/=53/-23	50.50%		50.5/100
2. Rybka  3   +23/=53/-24	49.50%		49.5/100
Total Result:

Code: Select all

1. RobboLito   +49/=111/-40  52.25%		104.5/200   
2. Rybka   3   +40/=111/-49  47.75%		95.5/200

How often now I have seen such a mess? How do you justify to mix the two samples if you tested with two different, seemingly important, contempt factors? Why not checking if more games with 15 would assure the almost equal result? At least you could have made some reflections and commented on your decisions. Such results are never talking as such, also in that more lower N scale.

No mistake, I dont want to demotivate you but I have learned a different stats. Why not giving something back to you?

Perhaps you have still more results?

Your criticism is well received. The reason I tested with contempt factor of zero initially is because some have claimed Rybka to be stronger than this engine using that particular setting. Perhaps, I will conduct more tests with default settings and publish the results.

The thing I don't understand is why you tested it with pondering on, when Robbo didn't have pondering implemented in version 0.085c2. So you gave an unfair advantage to Rybka.
If you want to test with pondering on, then try newer version of Robbi like e4.

Unless I am mistaking, pondering did not work in Arena GUI but worked in Fritz with that version.

I am checking right now, and I think you may be right

Thanks. I had a similar experience last night when I made the SWISS test. I had my Rybka on I think 452 MB memory and it wasnt on 55 positions. Then I looked closer at the description in the page of the test and saw that they advised 128 MB. I changed it and then got the best result. However it was late at night so that I stopped after the two tests. If would now want to become a tester I would at first try to find out what exactly the Fritz testsuite feature is about. Without I felt myself like a little robot. click click. No comment about the bckground activities on the PC nothing. But sorry I dont want to start nitpicking, later people would say, Rolf, this isnt science here, it's just our hobby, please let us play, that is how it started in 1996. Therefore thanks again for your openminded response. I like it. -Rolf

I downloaded and tested the suite also, and got very different results. Rolf is correct about the dubiousness of some positions. Notably 3 have no adequate defense, and thus avoiding a move does not change the lost evaluation. The positions in question are no. 3, 20, and 46. These positions cannot be saved with best play. No. 48 claims Qb6 to be the wrong move, proposing none in its stead. Even stranger is that the Excel file claims Robb gets it correct, meaning it avoids this move, but this is incorrect on both accounts. First, Qb6 is in fact the best move in the position, and second, Robbo does not avoid playing it.

Aside from this, there is also the issue of the results reported. Naturally I take into account the stronger computer I used to run the suite, but this only explains time discrepancies, not outright different results. I double-checked and triple checked my results, noting more than one discrepancy works to Robber's favor. These were all hand done, clearing the hash between engine loads, on a Core 2 Duo 3.6GHz with 1.5 Gb Ram for the hash.

In my testing, not removing the wrong positions, Robbo got 9 wrong, and Rybka 6. I used the 64-bit versions of the engines, but where results were radically different, I checked with the 32-bit version. The results were consistent.

It is also worth noting that the 64-bit version of Robber displays the exact same speedups Ryba does, when compared with the 32-bit version. Ex:

Position 18: SwissTest4_18 - Verteidigung, DeepShredder11-Bright02c, CompGame 2008

[d]r1bq1rk1/pp2n1p1/2n1p2B/3pPp1Q/2pP2P1/P1PB1N2/2P2P1P/R3K2R b KQ - 0 1

Moves to avoid: 12...Qe8, 12...Rf7, and 12...cxd3. Time allotted to find solution is 60 seconds.

RobboLito is reported to not find this within 1 min, and Rybka 3 MP in 18 seconds.

Questionable positions:

No. 3: SwissTest4_03 - Verteidigung, Aristarch45-TheBaron15, CompGame 2005

[d]r1b2rk1/2p2ppp/p2b4/1p6/6Pq/1BP5/PP1P1PP1/RNBQR1K1 w - - 0 1

Moves to avoid: Qf3, Re3, g3.

Unfortunately, white is dead and has no adequate defense. The only other tries, f3 or Re4, are also insufficient.

No. 20: SwissTest4_20 - L vs L, Eigenmann 2006

[d]5k2/5ppp/p7/3p1b2/5P2/5P2/PPBK3P/8 b - - 0 1

Moves to avoid: Bxc2.

Obviously the pawn endgame is dead lost after the exchange of bishops with the queenside majority. The only problem is the endgame is lost even with the bishops. Ex:

1... Be6 2. b4 Ke7 3. Kc3 Kd6 (3... d4+ 4. Kxd4 Bxa2 5.Kc5!) 4. Bd3 Bc8 5. a4 g6 6. Kd4 f6 (6... h6 7. a5!) 7. h4!

No. 46 Naum22-Hiarcs112, CompGame 2007

[d]2r3k1/5p1p/4pP2/1p1p4/1p1R3P/8/PPP3P1/1K6 b - - 0 27

Moves to avoid: Rc4.

It is true that 27... Rc4 fails, but Black has no way to save this position against perfect play. The only other try that comes to mind, is 27...h5, but I don't see any hope for Black after 28.Rxb4 Rc5 29.g4

No. 48 - Pepito142-LGoliath35, CompGame 2002

[d]r1bq1rk1/pp2bpp1/3pp3/6P1/4PPn1/2N5/PPPQ2P1/2KR1B1R b - - 0 13

Moves to avoid: Qb6

The problem is that this is actually the best move. :?

If one removes the 4 positions from the equation, Robbo got a total of 6 wrong out of 60, and Rybka got 3 wrong.

No, Rolf isn't correct (as always ;-)

These matter - ("...does not change the lost evaluation") - is explained in the article.

Probably there are some "bugs" in your analysis...:

No. 3 - Much better moves than Qf3?/Re3?/g3?: f3 and Re4 (Of course Black is still worse, but that's not the question...)

No.20 - Exchange of the bishops leads to a lost pawn endgame; in contrast these endgame B vs B has a great chance for a draw (I see no forced win for white after i.e. 1...Bd7 or Bc8 followed by centralization of the king)

No.46 - Similar to No. 20: Exchange of the rooks leads to a lost pawn endgame; the two rooks increase the chance to a draw. It's a matter of chess endgame knowledge (and a big problem for engines...)

No.48 - Qb6? Absolutely not the best move in the position; on the contrary, probably he lost the game.
Alternatives with the ability to compensate: ...Bd7 (with returning of material) or ...d5 (with counter play).

Thanks for your effort: Walter
