New version - Goyaz

[Wander Ferreira Jr]

Hi there,

After a long, long time, there is a new version of Goyaz!!!

Initially, I would just include the Transposition Table, but, with it implemented, I found a huge bug in my quiescence search, that was there since my previous version.

Now the entire engine seems to do exactly what I teached it . Just have to teach it more and more of strategy (doubled pawns, open files, etc.) and it will become better (I hope... ). Before finding the bug, these things just didn't do what I expected...

I didn't estimate it's new rating yet, but it's more than the previous version.

It's available for download in Goyaz's site.

Hello Wander,

I noticed that Goyaz 0.005 has a strange bug which makes it
repeat the last calculated move in the last move before the cut
in time controls moves/time.
In my case it always repeated move 39 in move 40 at a tc of
40 moves/ 15 minutes, which leads to an immediate loss, because
of an illegal move of course.

I have attached the appropriate debug snippets and the games below:

[Wander Ferreira Jr]

In my case it always repeated move 39 in move 40 at a tc of
40 moves/ 15 minutes, which leads to an immediate loss, because
of an illegal move of course.

I did see this bug in the earlier versions of Goyaz, but did not know which caused it... I thought that this bug was fixed in the new versions. But now I see that I just stopped to play 40 moves in 5 minutes and started to play 2 min + 12 sec.

Thanks for the tip. Now I will look for it and hopefully fix it soon.
