Chess Mini is a simple but interesting chess playing app. It uses the world's smallest chess engine - Micro-Max, coded in less than 2000 characters and 133 lines of source code. The entire source code can be printed on a single A4 paper and has less words than a high-school assignment.

Despite its smallest size, Chess Mini has a solid understanding of chess and a very broad opening repertoire. It loves to play irregular openings and you will always be surprised in the first few moves of the game. It is also able to play chess variants such as Fischer-Random and Upside-Down.

The engine has a rating of Elo 2000 on the Computer Chess Rating Lists and is stronger than 70% of the human chess players.

Are you one of the 30%? Can you beat the smallest engine? Download and challenge yourself against the smallest.

This chess game

This is one of the best chess games I ever encountered!

Interesting and non conventional play but lacks basic features

For such an interesting engine some basic functionality of the GUI would go a long way to enhance this app:

* Please allow the GUI to remember player names.
* Please allow games/PGN files to be sent by email.
* It would be great if one could jump to the start or end of a game.

instructiv and amusing

Only app out there with lower Elo rating. I don't like to adjust chess engines capabilities (with higher elo ratings) to lower level. It's like forcing a Grand Master play like a novice player. So I think this app is very suitable as Second for the Tournaments B Catagory players. Also the Author replies all questions swift.
