Better arrows! I don’t remember where but there is one place where drawing arrows in a knights movement creates an L shaped arrow instead of just a normal arrow. I love this and so implemented it into my program. I also added aspiration windows. Aspiration windows work on the basis that moves don’t usually swing the score by a lot. This means that when going down paths we can set the lower and upper bounds to previous score ± window size. This helps prune more paths. If we find that the score is actually higher than we expect we search again but without the aspiration window. This helps remove lots of the obviously bad paths which makes the program much more efficient. Next I am going to add zobrist hashing so that I can use transposition tables.
