I am very much a ‘hobby’ programmer with limited experience but have had a longstanding ambition to write my own chess program. It has been a frustrating but very rewarding challenge and also great fun and after many months it is now at long last done!

I have  made my documented source code available to help other people who are keen to write their own program. You can find out about aspects of the program on this page by following the links. Numpty, is not the best written or most efficient program, but importantly it works!

I could never have developed Numpty on my own. You can find a list of the references I have used and the people who have kindly helped me here.
