obscure java engines duking it out on a high level :)

[carldaman]

I ran a no-book 2-game match, pitting Mediocre 0.5 (by Jonatan Pettersson, Sweden) against Magnum (by Eric Stock, Canada) 4.0, two java engines that are not exactly household names, even among hardcore computer chess buffs. To my delight, the games were very entertaining, and total slugfests. The TC was 15m+10s inc. Enjoy!

[/pgn]

Magnum really delivered a swift and hard puncher's blow to the head and White was quickly KO'd.

The second game was an epic, intense battle that swung back and forth, ending up as a hard-fought fortress draw. Neither participant deserved to lose such a game.

I tip my hat to the two contestants,
CL

[adams161]

I was able to download Magnum 4.0 at its project page, https://code.google.com/archive/p/magnumchess/ ,(It's GPL) and extract the zip which extracted to folder MagnumChess_v4.00 then take the MagnumChess.jar out of the /dist sub folder and load it into Lantern Chess, http://www.lanternchess.com , with Options menu / Load UCI Engine and load the jar which i placed in the Lantern folder.

It seems to get similar depth to Mediocre Chess V0.5 in my limited analysis so far. but it might be a little positionally smarter. Testing a book move position in the Petrov Defense, Magnum found the #2 book move choice (using lantern's opening book) were Mediocre found a much less common choice that almost always drew. Have to play with it some more and compare the two. I"m particularly interested in how natural the play is i.e. can it find book moves seems to be one test.

http://www.computerchess.org.uk/ccrl/4040/ does not seem to have a rating for Magnum 4.0. I haven't been able to find a rating so far. I might be interested in including a second Java engine with Lantern as long as license is good to use which both Magnum 4.0 and Mediocre v0.5 are.

[adams161]

i tried cuckoo112.jar and it also looks very promising. it gets about 5 more plays depth than mediocre and magnum. Its rating appears to be 2576.

I might want to have one main engine to open on the Lantern options menu then below it a sub menu of 'other engines' and include some other java engines.

My strength estimate for Magnum is about 100 Elo points above Mediocre_v0.5.

Any luck getting Magnum to use an opening book? It seems to ignore the book in Arena.

Yes, it can use an Arena abk book. You have to first go under Book>Manage> and check the "Use Arena engine books" box. Then choose a specific book from Magnum's own Books tab (under Engine>Manage). It works for me.

Testing a book move position in the Petrov Defense, Magnum found the #2 book move choice (using lantern's opening book) were Mediocre found a much less common choice that almost always drew. Have to play with it some more and compare the two. I"m particularly interested in how natural the play is i.e. can it find book moves seems to be one test.

http://www.computerchess.org.uk/ccrl/4040/ does not seem to have a rating for Magnum 4.0. I haven't been able to find a rating so far. I might be interested in including a second Java engine with Lantern as long as license is good to use which both Magnum 4.0 and Mediocre v0.5 are.

My strength estimate for Magnum is about 100 Elo points above Mediocre_v0.5.

Any luck getting Magnum to use an opening book? It seems to ignore the book in Arena.

Yes, it can use an Arena abk book. You have to first go under Book>Manage> and check the "Use Arena engine books" box. Then choose a specific book from Magnum's own Books tab (under Engine>Manage). It works for me.

Thanks Carl!

I just bought Komodo 10.4 today and still haven't made any Rodent III personalities and like this Magnum engine as well and...Geeee...

How am I gonna get any work done?

I was able to download Magnum 4.0 at its project page, https://code.google.com/archive/p/magnumchess/ ,(It's GPL) and extract the zip which extracted to folder MagnumChess_v4.00 then take the MagnumChess.jar out of the /dist sub folder and load it into Lantern Chess, http://www.lanternchess.com , with Options menu / Load UCI Engine and load the jar which i placed in the Lantern folder.

It seems to get similar depth to Mediocre Chess V0.5 in my limited analysis so far. but it might be a little positionally smarter.

Good problems to have, Brendan!

I have a Winboard based Java engine you might check out.. chess4j. It's probably a good bit weaker than those but it is very stable and includes a small but fairly high quality opening book.

It's released under the MIT license.
