Man vs machine - how to beat chess engine

[pocopito]

On the other hand I guess games in which you lost but got a superior position could be interesting too (specially if you lost due to a blunder)

[Kingghidorah]

I went over the games quickly and it actually showed where Miroslav could've won quicker in some games. I did notice though that Critter 1.4 x64 version made better moves where it lost with him playing 1.4 x32 but all in all it looked like he beat the programs fair and square.

[zullil]

Just check this positions more times. You will find that at the same depth engines doesn´t play always the same move...

Yes, this is true for parallel searches. In the search below, Critter does consider c4 for an instant. But the move is rejected at depth 14, in less than 1 second. It seems very odd that Critter with 3 threads and 256MB hash would play c4 on move 7 of a 5-minute game.

Not sure what is going on, but I suspect the engines you are defeating are much weaker than they should be.

Dear Kvicala Miroslav,

Just my two cents over this issue

Wow,wow,wow...it seems:
-You are Hero
-You are Star
-You are Genius

But however, i challenge you to play with my engine
My Conditions:i7 980X;10 games;5 min;Houdini 2.0c;Perfect 16 book;LIVE (against any cheating)
In case of any win by you or even ended with a draw,you will get a prize 5000 USD (by me)
And in case of 10 wins by Houdini against you,then you need to pay me 5000 USD

Are you ready for a such 'Challenge' ?

I hope you will agree...


Best Regards,
Sedat

Now that is a "Put your money where your mouth is" type of statement if I ever saw one!

[Don]

I don't have any reason to dispute your findings here - but I know that it's possible to beat a chess engine, it's just not likely, especially on a modern CPU. There is a pretty big difference in a powerful desktop system and a mobile device so I'm much less impressed by that.

There is also the issue of how to verify this - you add at least 100 ELO to yourself every time you are allowed to take back a move. It's not that we don't trust you but still a certain amount of verification is needed when the claim is incredible.

I know that it's possible to learn to beat a computer if you simply play it over and over again using the same plan each time and the same level and settings. Although the games will vary, if you stick with it you will learn how to handle all the ways it will vary and learn by trial an error. If the level and settings are the same you will only get a reasonably small variety of different "pathways" you must learn to beat it. To avoid big opening book variety you just find sound openings that are somewhat off-beat so that you get just a few openings.

I used to do this with the fidelity machines, but of course I could beat them once in a while without doing this. But I found a way to beat it every time which required learning only a few variations and figuring out what it takes to win. I think modern programs vary more than the old programs and it will no doubt be a lot more difficult also to find a way to win but it should be possible. Once I was a piece up I didn't memorize anything after that as I could just beat it on my own but that may not be so easy with a super grandmaster strength program.

Many people thinks that at the present time chess engines are too strong to make some good results against them. I would like to decline those myths. Even very average player (FIDE ELO 2000 and higher) may be able to get a lot draws and some wins againts the strongest engines. I am very average player but I can beat most of engines on my Samsung 9220 and even on my old quad (Q6600). I must note that the question is not how strong are you but how can you adapt your play style against engines. That is the reason that average player with a lot of experience with engines may get better results than GM. Before I post some games, I would like to define general rules which must be respected to achieve good results.
1. Opening choice - there is no chance to play any Sicilian defence or openings like Moscow system, human is simply smashed by calculation power of engine. Very good opening choice anainst engine is Russian defence (especially system with Jc3 Jxc3), Caro-kann (system with g4 attack), many lines in French defence (strategy is much more important than tactics here), against some wekaker engines even Evans gambit can be used. But the weakest opening for engines is king´s indian defence (human can win with both colours - if computer has something like general book 8-9 moves).
2. To keep comfortable draw it is necessary to have symetrical structure of pawns on both sides and to keep at least 6 pawns on chessboard (each side).
3. Right now engines are absolutly superior to human in tactics late middle game (especially Houdini is really king of the hill) and endgame are also at very solid level (with table bases). On the other hand every engine is limited by it´s horizon. That is why opening lines with pawns sacrifice and clear attacking strategy are so unpleasant for engines.
4. Maybe it will sound little bit strange but thera are hihger chances for human playing 5 minute blitz than long games - it is also associated with horizon which I discussed earlier.

Before someone will accuse me that I was playing against engine level 1800, here are engines settings:

For Samsung 9220 (2 cores 1,4 GHz, full strength, ponder on,Droidfish GUI)
For Q6600 (3 cores for Houdini and all engines that support more than 1 core, 256 MB hash, ponder on, default ponder) - someone may tell that increasing contempt will reduce my chances rapidly but on the other hand original setting is the strongest and engine doesn´t know who is his opponent. When Houdini is playing on playchess it also doesn´t change it´s contept playing weaker engines or slower PC).

Well, let´s see some games:

and many more similar results...

I don´t know exactly the statistics but it will be something like 1 win - 5 draw - 20 lost (all played with white). Playing with black pieces I won only two games and lost maybe 200...

This looks maybe suspicious...nut human have one big advantage over computer evolution. If I find out that some opening or line is not suitable, I am looking for something different. If I find better opening, I chech the lines that engines play, if I lose the game I can learn from my mistakes and next time I play better ...it is something like Hiarcs auto-learning function...if you let play Hiarcs many thousand games against Houdini (few openings or lines) it will improve it´s performance and in some point it will be able to beat Houdini. I use the same procedure but of course every human can learn and improve much faster...it is no magic...everybody can make some wins and draws too...

One more example from today...played on smartphone...

[overlord]

Nobody is able to play against something better than normal general book. I have free style book and would never get a good result using it. Moreover i7 performance is far higher than old Q6600 or even the best smartphones...it´s performance is similar to old Pentium CPU. Another factor is content - if you put higher value...human chances decreases drastically, but I am seaking about normal setting...nothing specially tuned against human being

[overlord]

On my smartphone I have 32 bit version of Critter. I don´t know if it is the same version as for normal pieces. Maybe author could tell more.
