I looked over the Slibo 0.4.8 games because this didn't look right.
I discovered that it likes to "sacrifice" a piece early on in most games, usually on the kingside.

When I then looked at its games from the 16th Division 8 (from which it gained promotion into this division), I found that the same thing was happening in those games too, but with more success against the weaker opposition.

So, definitely looks like a feature or bug.

Replace it with 0.4.4 if there is an executable :)

Hi Harun,

I emailed the author, so I'll see if I get a reply.
Did you notice this feature in earlier versions? I must try and find my 0.4.7 games.

Cheers,
Graham.

I noticed that Slibo 0.4.8 seems to like "sacrificing" a minor piece on the kingside early in most games, only to end up with pretty much a lost game.
Not sure whether it's a feature or a bug, but Slibo would be a lot stronger if it didn't do this.

Response:

Well yes, I somewhere made sacrificing a minor piece cheap, to make the playing style more "entertaining".
Maybe I have overdone it a little. I will have a look at it. Anyway, thanks for the suggestion.

Thx Graham. Slibo is one of the new engines that I have not tested.
The version in its web site is 0.4.4. Or am I wrong?
Which versions were made public up to now?

Hi Harun,

Slibo 0.4.8 is available from Jim's site.
The author is writing a new engine which shouldn't be too far away:

I am doing a complete rewrite (almost done), the new engine is called hayabusa. It will have a complete new evaluation and hopefully be much stronger.
