son of Mainsworthy winboard engine release

[mainsworthy2]

SonOfMainworthy02 Its just as bad as dad, but plays a little bit better, seems to be more aressive in play and a little bit more defensive setups. I didnt realise how much a little fiddleing can change an engine its available here

I'm confused about the version numbering.
SonOfMainsworthy engine prints out the version number as "2.9.6",
also the name of the program in your zip file is:
"SonOfMainsworthy2.9.6 WinBoard Arena Chess Engine.exe"

You say "SonOfMainsworthy is now updated to 04."
What is "04"?

hi Ron

It was 0.1 then 0.2 then 0.4 then 2.9.6 the ones inbetween were outdated to quickly to put online!Im a messy programmer 2.9.6 is upto date. sorry for the confusion , Leo site is where its hosted thanks to Leo! http://wbec-ridderkerk.nl/index.html

It beats ACE no books 9 out of 10 and 10th is a draw, chad's chess just pips it so its getting better

Do you consider this a new engine or just a new version of Mainsworthy?

Guenther

[mainsworthy2]

Hi Guenther, Ive reused the old engine, and redesigned some of the code and added another ply, its a very different engine I would say because criticle code to mainsworthy has changed, and plays nothing like mainsworthy.

I have sorted moves , captures are evaluated first, and added a ply, also redited the eval function! Im also experimenting with different weights and measures for the eval. and have expanded a couple of functions hope you will enjoy when Ive the finished engine , so you tell me is it a different engine? I didnt wat to lose the onld mainsworthy as it was a stable engine, so Son was born

Im nearly ready for another update, so keep checking

[mainsworthy2]
