Hi!

It's a known fact that chess engines don't understand King's Indian.
To play it well requires long term strategic planning. So it's not a surprising for that even a low rated player can be win a top-computer every now and then.

But to prove your point, I think that instead of posting the chess games here, you should create account in some internet chess server and play against machines there.

When playing with your own PC, it's possible to quickly restart game after your blunder, choose a book for engine that fits your purpose, restart immediately if engine doesn't follow the book line you wanted etc.
And then post the one game of 100 you won/drew. Some even use takebacks. It's also possible to use engine in analysis mode beforehand and try to find positions where engine is likely to blunder...

All of these things make the match very unfair for the computer. But if all games are played on the Internet server, anyone can check that no dirty tricks were used.

Regards,
Joona

Hi Joona,

soon I am going to have holidays but after that I try to make some video where everything will be clearly visible. By the way what is your estimation for strength of Stockfish on Samsung SII (2x1,4GHz, ponder on)? Playing against PC (especially i7) is different story. Moreover if engines has a good book it is much more difficult but I wanted to give a proof that it is possible to beat engines with limited book (Stockfish book from Droidfish is used if the game is not played on PC). I have posted games in king´s indian defence because it is the only one opening where I am able to beat engines Anyway if you will check more games you will see that it was played without any help - I have already posted also some lost games (of course that I lost most games against Stockfish, which I like very much because it is original engine for free style games and correspondence games too - in combination with Houdini). Here is the newest game against one of weaker engines (this time it is fianchetto king´s indian defence).

Joona belive me, they (Czech people) can do a wonderfull beer.
I think that Miroslav is able to play against chess engines with some good result. Engines have a few weak points and a reasonable man can use it. Engines without knowladge of opennings, strategy and egtb are now vulnerable in many positions.

Mister Kvicala Miroslav.

Estudié sus juegos; Me han gustado mucho los ejemplos; Las partidas son bellísimas, extraordinario trabajo de Kvicala Miroslav, a quien felicito por esas verdaderas obras de arte anti máquinas.

En lo personal, yo no sabría jugar de la manera tan bella como Usted lo hace.

En mi humilde opinión, la efectividad parecería no lucir tan consistente como el anti ajedrez; 1 victoria y 1 empate contra 20 derrotas jugando blancas, y 1 victoria contra 200 derrotas con negras, representaría promedios más bajos que los del antichess.

De otra parte, creí entender que se complica mucho la nueva técnica jugando contra poderosos hardware, lo que no sucede en el anti ajedrez que mostró efectividad jugando 60 +15 contra 200.000 kilo -nodos por segundo de velocidad de calculo contra un hardware no comercial que me suministraron en la sala de máquinas en la “Golden Era de engines room” de playchess.

Repito; estás nuevas partidas son realmente bellas; lo felicito y me da una gran alegría saber que hay personas como Usted que representan ël arte creativo de la mente e inteligencia humana"

Cordialmente,

Pablo Ignacio
