Little ChessPartner 1.12  - December 2006
----------------------------------------------

Before using this software be sure to read the license
agreement in the LICENSE.TXT file.


LCHESS has been the predecessor of ChessPartner, as a design study a Java version has been derived from it, this version is named: "Little ChessPartner".
Is has not been fully ported, just a small part of it ! A program written in Java is much slower then a program written in C or assembler, thus the playing strength will be much less as well. Note: This program is still under development, so please come back often, also feedback is appreciated.

The applet has been made freeware, you may download it and use it on your own website.
To use it download the zip file and place it in a directory on your web server.

<applet
    code=jchess.class archive="http://yoururl/jchess.zip"
    name=jchess width=400 height=400>

	window.alert("OnDoMove(" + strMove + ")");
}
function OnNewGame()
{

For security reasons, a Java applet and JavaScript can only communicate together
if they are allowed to. This is done easily by adding the MAYSCRIPT attribute to
the APPLET tag.
