Myrddin v0.80 Alpha 1 release

[JVMerlino]

Greetings,

After another 10 days of work since my previous post, and one shocking win on ICC, I'm ready to release the first version of my engine, Myrddin. I got lots of encouragement and just decided to go for it. Many thanks to Roman Hartmann for help with one specific issue that was almost certainly too silly to even ask.

I don't have any file hosting at this time, so please just send an e-mail to JVMerlino@aol.com asking for the engine. If anybody who wants to make the engine available for download, please just ask for permission first.

There's a ReadMe file included in the package, which should tell you everything you need to know.

As for the "shocking win", it came against QGChess in Myrddin's one and only matchup against that very competent engine by Justin Bartlett, rated 1565 at the time. I don't have an ICC account yet, so I used the old CM9000 account from the 4-game match against GM Christiansen over six years ago.

It is always nice to see another new program and programmer. Writing a chess program is somewhat like having a child and over the years as we work on improving it we take pride just as we would if it really was our own child.

Hi Dr.Deeb
Somewhere about 7 or so years ago when I first discovered this site I gave a copy to everyone who wanted one. My first program was written in Basic and only searched one ply. I had also put it on AOL as I used to that server at the time.
Also during CCT4 I entered the latest version but because I could not implement Xboard at that time I was not allowed to enter any more on line tournements. You might still be albe to find both versions on the internet. Just look for my name or the name of my program which was "The Warlord".

I do not know what exactly our doctor wanted to download from you, but I will be clear: If you have a DAUGHTER from 30 to 59 years in good shape, I would like to download her and perform some test.
Nothing indecent, just some testing...

Leave it to you to take a perfectly boring announcement about a new engine and turn it into a topic about young women.
