The third version of my chess engine, Shallow Blue! Please try it out on TurboWarp for much stronger play: https://turbowarp.org/1193825236 Many thanks to the lovely people on the Game of Kings forum, they have been a major source of motivation and knowledge for this project: https://scratch.mit.edu/discuss/topic/248984/ Credit goes to the xiphos chess engine on github, I used its PSTs as basis for some of the PSTs in this project, heavily modified to suit my needs: https://github.com/milostatarevic/xiphos
