A Parallel AI Chess Game from Level 1 to Level 10 made with Java Swing

NOTE: Archived this repo, for latest code, check out the link below

https://github.com/GervinFung/LibGDX-Chess-Game

A simple 2 player chess AI that implemented minimax & alpha-beta pruning & move-ordering & pawn structure analysis to fully optimise the AI with a proper FEN file format

I screwed up my previous chess game with bad design and without planning ahead

I decided to make a chess game because my pc do not have one

Errors in test

Hello, I was looking the code and i saws that in the test folder, there is an error in every calss due to an import you put.

testing

Also, i would like to add a few other issues I saw while I was ruuning the code. First, when playing with the AI after i put it to level 2 and higher it takes forever to make a move (in a particular moment it took about 1.30 min ) and when i put it in level 6 it crushed after some time. (first screenshot)
Secondly , (2nd and 3rd screenshots) , i did the same moves (left and right) , so did the AI and it never ended (i had to manually end the game if i wanted to start a new one) . What i mean is that even though it is in a position that there is no way i (white) can get out , the game lets me do infinate loops of the same moves resulting in being stuck.
I hope this makes sesne
thank you
