1. INTRODUCTION
-------------------------------------------------------------------


The great majority of the chess games use technical of
artificial intelligence to calculate its plays.

These techniques consist basically, of going moving all the
pieces of the checkerboard to all the possible positions.
Such be can continue until several levels, but each additional
level involves the increase in time in the I calculate, though
logically, the time reduces in you scheme but potent.
How much but levels travels the computer, better play will make.

The computers can earn 95% of the chess players, the reason of
this is simple: the computers commit less mistakes!, what does not mean
that they play better, but check all the plays in few seconds, while
the human normally, only checks some few.

The objective of CHESSAI is not to check hundred of thousands
of plays to make a perfect play.
We have preferred to make a game, with a similar level to that
of a normal player, Chessai has a balanced game level, of this form,
are procured play more exciting for the player, without the computer
must play worse.

If yourself likes the chess we wait that enjoyments with this
game, since that is its final objective. Recall that this program
is distributed under the shareware concept, if you continue it
using after a period of test considers to register you. Thanks you.
