Shortest Chess Games between two Chess Programs

[Spacious_Mind]

In the Computer Chess Club: Programming and Technical Discussions Forum someone posted today a game where the program was checkmated in 8 moves.

This made me go back through my collection of games played between programs to see which were the shortest matches played between two computer programs.

The shortest that I have experienced playing two programs is a checkmate for Black in 6 moves:

[d]rnb1k1nr/ppp2ppp/8/1Nb1N3/4pP2/8/PPPP1qPP/R1BQKB1R w KQkq - 0 7

Systema Computachess played at it's maximum level with takes about 20 seconds to move. It ranks amongst one of the weakest computers ever sold to the public

As a win for White the shortest match I have experienced is a checkmate game in 7:

[d]rnbq1b1r/ppp1pppp/3p1n2/1Q1P4/1k2P3/4B3/PPP2PPP/RN2KBNR b KQ - 0 7

This game is really amusing to see Black's King moves It is amazing that the Software Company Mastertronics actually sold this program for the Commodore 64 at British Pounds 1.99 in the 80's. Master Chess was easily the worst Commercial Program sold for the Commodore 64.

I would love to see some other gems from you all. From my experiences so far the shortest checkmates seem to be more likely wins for Black than for White in games between chess programs.

Has anyone else played games between two programs with checkmates in less moves then shown above?

Best regards

This game is really amusing to see Black's King moves

It has the same playing style as my shell script. But I guess it could have searched twice as deep without seeing that mate.

The topic makes me wonder how quickly (in theory) a fixed-depth blind searcher can be mated in the opening...

Maybe it is not what you are looking for. Anyway, all the games than ended with mate in 7 or less moves in my Battle of the Forgotten tournament:

As you may notice, the constant in these games is Brutus RND, a random mover created by the same author of Brutus, Stephan Vermeire. Kind of cheating.

Anyway, there is one game where Brutus RND was not in:

Maybe it is not what you are looking for. Anyway, all the games than ended with mate in 7 or less moves in my Battle of the Forgotten tournament:

Hi Carlos,

That is too funny I thought dedicateds had some of the weakest programs ever created!

I might just have to play Brutus against some of the weakest dedicateds to see who is the BEST !!

Thanks and best regards

Note that this is Brutus RND, a derivative of Brutus that implements a random mover. It just randomly selects from all legal moves, with equal probability.

That engines without search sometimes also have the upper hand, is shown in this game of NEG 0.3d (a program that plays only by SEE value and piece-square tables, does not know what checkmate is, but has a built-in preference for checking moves when it has to choose between moves of equal SEE value):

Code: Select all

In 156 games, Brutus RND (just a random mover as H.G. Muller pointed out, the real Brutus 8.05 is a strong chess engine) won 4, drew 2 and lost 150 games. His wins were by illegal moves made by his opponents (Pos and Omar). Here his 2 draws:

As you can notice, Brutus RND had a lot of luck to get a draw in those games. The same with his wins. The games are entertaining though, at least for me.

If you play it against Pos 1.17 often enough, it will probably get a win by checkmate. Pos has the funny habit to immediately march its King to the center, where t is easily checkmated by accident.
