This is a chess engine based on a Convolutional Neural Network

To run:

• Might need to pip install requirements.txt and erase the upcoming errors
• If you want to see it play against stockfish engine you need to download and make said
• Else run the game_manni.py file and type game_AI() in your IPython console

It is far from being a really good chess player, rather than it showing how one can utilize modern machine learning with only a few lines of code Problems with the algorithm are but are not limited to:

• Strategies cannot be palyed as a whole
• The CNN is trained on games of Pro players with a ELO rating higher than 2000 this causes the problem that it is rather confused with the enemy player making 'stupid' moves
• The endgame phase is hard to read for the machine since the informartions are very limited (having only ~6 pieces on the board)
• Looking into the future moves of the enemy only happens from the experience it learned from the training games rather than a search tree

The board and the corresponding training sets are encoded in a so called bitmap which means a boardlayout is represented in a matrix of the form 8x8x13 This 8x8x13 matrix holds the following information:

• Channel 1 [:,:,0]: The corresponding positions pawns belonging to the machine itself

• Channel 2 [:,:,1]: The corresponding positions bishops belonging to the machine itself

• Channel 3 [:,:,2]: The corresponding positions rooks belonging to the machine itself

• Channel 4 [:,:,3]: The corresponding positions knights belonging to the machine itself

• Channel 5 [:,:,4]: The corresponding positions queens belonging to the machine itself

• Channel 6 [:,:,5]: The corresponding positions king belonging to the machine itself

• Channel 7 [:,:,6]: In this channel the last three own moves are encoded in order to be able to have a bit of strategic understanding

• Channel 8[:,:,7]: The corresponding positions pawns belonging to the enemy player

• Channel 9 [:,:,8]: The corresponding positions bishops belonging to the enemy player

• Channel 10 [:,:,9]: The corresponding positions rooks belonging to the enemy player

• Channel 11 [:,:,10]: The corresponding positions knights belonging to the enemy player

• Channel 12 [:,:,11]: The corresponding positions queens belonging to the enemy player

• Channel 13 [:,:,12]: The corresponding positions king belonging to the enemy player
