Updated: Mar 15
3293 Elo !
Stronger and stronger this Pawn :)
The author of this engine, Mr Rui Coelho publishes Pawn under the GNU General Public License v3.0.
I have been closely following the development of this engine.
The author "fought" valiantly for every Elo point.
And although the road to the official version 1.0 was not strewn with roses (unstable operation on Windows), Mr. Rui Coelho did not give up. Eliminated the bugs and the result of his work is the latest Pawn, playing really strong chess.

Here's what we can find out about Pawn-1.0 from its creator:
The first official release of pawn, after over 1 year and a half in development.
The engine uses a hybrid evaluation function combining both handcrafted terms (such as material, mobility and king safety) and an efficiently updatable neural network for positional scores (derived from a set of trained PSQ tables in earlier versions).
All training data has been generated in self-play at low depth using the tools in the branch data_gen. The default network is embedded in the binary file with incbin.
I am pleased to announce that the official version of the Pawn-1.0 engine is bug-free and works properly on Windows, Linux and Mac.
Pawn is an advanced chess engine whose strength is on the level of Ethereal 13 and Komodo 12 engines.
Here is a sample of the tactical talent and power of the Pawn-1.0.
Its opponent Stash 34 plays with white, Pawn 1.0 has black.
The fortified position of the white King, with two Bishops and several pawns in defense.
Black's move. What to do to approach the enemy monarch ?

Brutally smash the white position !

At the price of Rook, the Pawn chess engine won this game in a spectacular by giving a mate to the white King in the 39th move.
To Mr. Rui Coelho, I congratulate him on the release of the first official version 1.0 and compliment him on his determination to successfully develop the chess engine.
