So many "goto" in the source code. 🙂

Oh, i thought that was for the pieces. "Goto Queens Pawn"...

...and no comments. Not a single one!

It's almost as if the code was generated by a decompiler. Not that I think it was because then there would be comments :classic_smile:

Can it play chess well? Or is it interesting because it's Pascal? 

It's old chess engine written in Turbo Pascal.

It's good for beginners and not only. You can increase / decrease engine default thinking time with + / -. Executable created on Windows 10 with Delphi Community Edition is in the folder Delphi. 

So just enjoy chess and power of great Turbo Pascal.

I think it's clear.

I'm reasonably well know in the field of computer chess and competed in the 2015 World Computer Chess Championships. Although Delphi is my first language, my engine was written in plain old "C". However, there are a number of strong open source chess programs written in Delphi. Here are a few:

 

Booot:

Open-Critter:

Where is DeepBlue in that list ?

Is this just an open-source competition, not comparing the leading engines ?

DeepBlue is old news. Things have moved on. Stockfish is king these days.

I believe so too, but DeepBlue is worth mentioning, isn't it ?

Isn't this evolving too, with never versions, or is it a complete dead project now ?

At least it was the first beating the human chess wolrd champion, should be a little honoured IMHO.

Deep Blue was IBM’s pet project from the late 90’s and has never been available for public scrutiny. It’s estimated strength is about 2800 ELO. To put this in context, if the latest Stockfish, running on a iPhone, played 100 games against Deep Blue it would win at least 95.
