I am quite baffled why almost every engine selects conservative first moves in the main lines like h3, Qc2, instead of more critical lines. Anyway, Rybka went down in flames.

I will post it here as well in case anyone misses it: a patzer can block up the positon and draw Stockfish easily as white.  I am a very strong chess player but I didn't even need to show it and anyone rated 14-1500 could play the game below

Wanna know how it felt to play Deep Blue on a personal computer? Well, nostalgia buffs, you can.

From a study in 2006 with the program version that the same year beat Kramnik:

In positions such as the 17th move from game 1 of the match, Deep Fritz (with the black pieces) plays the same move as Deep Blue and anticipates the same continuation. The evaluation is to a depth of 16 plies (8 moves) topping out at 4.737 million positions per second with all four CPU cores at 100% utilization after roughly 3 minutes of analysis.


Editors note: it was discovered that the multiprocessor implementation was not working, resulting in Deep Fritz only utilizing 1 core when set to 4 cores.

I can confirm however with the bugg fix 10.1 that it indeed plays the same continuation after several minutes, and this game was no exception. Deep Fritz 10.1 has the highest overlap/ponderhit rate with Deep Blue out of all its generation of PC-programs. It naturally discards some of its moves but the average move overlap is substantial.
<No point complaining about the moves an engine makes when you direct it into a line that is weak and the engine author(s) sought to avoid.>

Irrelevant what the book author intended. What matters is the objective nature of the position, and the position is approximately equal after e6. No problem having the engine play it out. I don't know why the author put a question mark on e6.

2017 UPPDATE: On my Asus Notebook 2CPU, Deep Fritz 10.1 still has Qb6 as the principled variation after 21 minutes =0.12:yell:
Since Tord Romstad of Stockfish fame claimed Hiarcs had by far the best evaluation heuristics of all engines, all else equal, I decided to test this notion by playing with opening book off. I don't own the latest version.

I played very conservatively and Hiarcs FOUND a tactic on h3 for a perpetual, which I also spotted after Bd6 was played. 16..Rxd5?? traps my rook. Maybe the human-like hype wasn't hype after all. Well done Hiarcs!:cool:

Have a look at this game: All Rybka versions struggle to see the combination after g6??

How the search functions is just as relevant as the evaluation heuristics guiding it. Deep Fritz 10.1 searches more extensively, but less thorough.

58: Bxb5 leads to a theoretical draw. Rybka 4 knows this. As does Deep Fritz 10. 0.00 scores.

I thought Stockfish and Shredder had more endgame knowledge? Deep Shredder 11 does not recognize the drawn position either.

Just goes to show you that search improvements can only take you so far. He would have to make a major revision of the evalulation heuristics to make bigger leaps.

For anyone doubting that the evaluation remained untouched, my draw below vs Fritz 15 was easily reproduced in Rybka 4:

White: Rocket

Black: Fritz 15 64-bit, 2 core

Result:½–½

In the game below, Deep Fritz 10.1 concidered winning the queen and two pawns in exchange for a knight, bishop and a rook, to be favourable for white.

The reality is that this material count favors black. White is strategically lost and has to fight to hold a draw.

If your engine conciders the position advantageous for white after the trades.. you are well adviced to tweak the parameters, because it is strategically close to lost.

Haven't checked version Fritz 16 but Fritz 15 was basically a Rybka 4 clean up, although I did find a position in which the material value appeared to be changed. But that could also simply be the newer engine seeing deeper in that particular position.
Also if you play a MMX engine vs a Bitboard engine on a 32-bit computer, will the bitboard engine be at a greater disadvantage?

I found when I played an oldie Fritz vs Stockfish on 32-bit computers that Fritz scored quite a bit better (more draws). I have seen more draws in a fewer amount of games than in hundreds of games on the 64.bit computer. It can't be a coincidence.
Topic Fritz 16 by Vas Rajlich coming By rocket Date 2017-11-14 17:59
Speaking of CEGT. Why is there such a large discrepency between them and CCRl? On CCRL 40/4, there is a 19 elo difference between Fritz 15 and Rybka 4, while CEGT has it 55 elo difference!
Topic Fritz 16 by Vas Rajlich coming By rocket Date 2017-11-13 14:56
That's still a bold prediction.Fritz 15 was not even 40 elo stronger than R4
Kramniks nemesis Deep Fritz 10 (.1) forte seems to be simplified queens pawn games. Here it holds two whites in a row in openings selected by me. Both had 2 CPU

Just because the threadmaker asked...

I will play tournament time controls (120/40) 1 CPU between Deep Fritz 10.1 and Stockfish 8.

Let's say 20 game match.:cool:

I predict 19 wins, 1 draw for S8
What was the rating difference between Deep Fritz 10.1 and Rybka on Playchess?. That would be an indication of which of the two was more effective aganst humans (albeit online).

Deep Shredder 10 was apparently 3650 on ICC, and is 75 elo weaker than Deep Fritz 10.1.
One thing that interests me is if Deep Fritz 10 would obtain a higher human elo than Rybka 4, simply for being anti-human (avoiding blocked positions and steering constantly to open positions where humans struggle.) on the other hand, Fritz plays more dubious too.. And might lose more.

"Father" is well known anti computer guy who exposed how oblivious Rybka was to blocked positions/fortresses. It didn't matter how much rybka 4 users tweaked the parameters on playchess - it was a fundamental blind spot in the evaluation function.

>anything above fritz 10 is probably stronger than Carlsen on decent hardware....therefore a waste of time to try and play. LOL<


How come then I mated Houdini 3 easily...

Topic How does null-move generate oversights? By rocket Date 2017-06-13 00:41
If a null move allows one side to move twice, without generating any threath to the position for the evaluating side, is that line discarded (no longer evaluated) or how do oversights arise?

Frans Morsch, one of the most prominent original users of null move claimed that null move invariably results in occasional oversights, despite the fact that Fritz examined a lot more positions per seconds compared to most other engines.

Fritz is built around a selective search technique known as null-move search. As part of its search, Fritz allows one side to move twice (the other side does a null-move). If the position after the null-move does not return a high value in the evaluation function, then clearly the first of the two moves did not contain a threat. This applies to 95% of the moves in a search. Detecting such moves before they are searched to the full depth is an excellent method to speed-up the search. In its latest version, Fritz manages a 10-times speed-up over a version without the null-move search. Selective search unavoidably introduces oversights, but these are few.

You are comparing DF 10 on one core with Deep Shredder 10 on 4 cores. Version 10 only used one core at 4 CPU, it was a bugg. Deep Fritz 10.1 is with correctly functioning multiprocessing and has a higher elo than Deep Shredder 10 at all time controls. It does not have any changes to its game playing algorithms.

Thanks. Finally we can put to rest the myth that Shredder was the top endgame engine back in the day... DF10 understands blockades, king and pawn endgames, etc MUCH better than any engine of the same era.

I do question your statement that Eigenmann test is knowledge based however. I don't think any modern programmer has the chess elo to add any new cutting-edge endgame knowledge. I would be very surprised if Stockfish 8 or Houdini 5 has endgame knowledge not present in Deep Fritz 10.1
Topic Eigenmann Test Your Knowledge Engine Results By rocket Date 2017-06-09 13:51
Can you add Deep Fritz 10.1 to the list? I'm sure it does very well.
Rybka 1 versions material imbalance were quite sophisticated compared to other programs. It has a very little effect on elo though. Why? most games follow normal paths and don't end up with material imbalances. There is an estimated 20 elo increase for optimized material values, have that in mind....

Rybka had several evaluation terms the same as Fruit, yes. However, I'm quite sure that Shredder, Hiarcs and Fritz shared much of the same evalation terms too, because a) it's standard chess theory to include certain terms and b) they often exhibited similiar limitations in positional play.

I have yet to see you adress the experiment proposed were the overlap was only 58%
The Draw rate of an opening is pretty irrelevant if there's a huge ratings gap. That's probably why you had surprising results in your Fritz 15 matches.

No opening book was used. Deep Fritz was running on 2 CPU. Interestingly, Deep Fritz elects Bd6 (instead of Bb4 or Be7), inviting my reply c5 which it evaluates as overextension.

I remember Kasparov suggested that Deep Fritz 10 against Kramnik with opening books off would have been an interesting encounter, for the possibility of more novel play.

I wrote "brute force style". Example of brute force style engine is Fritz of the 90s and early 2000s. Example of a selective search engine is Junior.
Is the hardest level of sparring mode in Fritz gui the default engine strength, or is it still weakened?
Objectively, yes. Deep Fritz 10.1 played  144..c5 because it did not want to settle for a draw by 50 move rule in a superior position (because of no pawn advances). It did however deem the resulting position 0.00 (which is wrong).
If you had Deep Fritz elo and played a mere mortal, with a superior position, you might have done the same. There were ways for me to go wrong in that endgame.

If c5 was reported losing for Fritz it would have played a non pawn advancement  move and be content with a draw by 50 move rule.

Yep. It's like a bad Sicilian Dragon for black if he castles short, which Fritz did. I mate on the H-file, but the c-file is in this case not opened.

I think Deep Fritz 10 (White) plays identical to a Super GM positionally here.

Qe2 is a known line.
Fritz reported an advantage of +3 at one point. Not enough!

But the engines don't know that vast amount of theory dictates that line X should be played a certain way... It only operates under generalities which are quite flexible to what the search shows. When opening book is switched off that is.

Here is a game I just drew were I was in fact  winning +1.20 (according to Stockfish) in the final position against Rybka 4.1, 2 cores with opening book off. But it was 1+1.

Opening theory was not developed through calculations... Humans took each position step by step and later recieved assistance from old Engines like Fritz 1. Modern Engines play c4 in the Queens pawn games (including Rybka 4). They understand the concept of gaining space and not just developing pieces.
But Rybka opening book does include the Dutch. And even played it in tournaments. This suggests the stats were quite decent for black and no reason for the Fritz team to reject it.
