MadChess 2.0 Released

  By

I have released version 2 of my chess engine. I’ve rewritten the engine from scratch in a more procedural style code- as opposed to the sub-optimal (for chess engines at least) object-oriented style I used in MadChess 1.x.

The engine is about 115 – 160 Elo stronger than its predecessor, depending on time control. I estimate it is about 2350 Elo.

Source code and EXEs available on the Downloads page.

MadChess 2.0 Beta Build 127 (Limit-Strength)

  By

I have added parameters to limit the playing strength of MadChess 2.0 Beta.

The simplest way to limit the playing strength of MadChess 2.0 Beta is to set the LimitStrength and Elo parameters. The engine will automatically configure material scores and positional knowledge.

In addition, the engine will configure search speed (Nodes Per Second), move error, blunder error, and blunder percent based on the Elo value.
