Release Notes 1.83c

January 15, 2013


This is a beta version so it can play in two [ 1 ] [ 2 ] starting tournaments. It's not even one

month old since the release of ProDeo 1.82 but plays obvious better as can be seen below.

The crude and unpolished new code will be tuned hereafter.

As one can see by the depth statistic this version calculates almost one ply deeper during about

all stages of the game. It's the base of the improvement.
