'''Planner''',<br/>
[[Jonathan Schaeffer|Jonathan Schaeffer's]] first chess program. When Schaeffer started studying computer science at the [[University of Waterloo]] in 1979, he met [[Ron Hansen]], co-author of [[Ribbit]] and [[Treefrog]], who generously gave him a copy of his program, which Schaeffer used to learn how to write a chess program.
For his master's thesis, he translated the [[Fortran]] program into the Z programming language (similar to the well known [[C]] programming language), as a code base to implement own [[Knowledge|chess knowledge]] and [[Planning|long range planning]].

My time at Waterloo greatly benefited from the presence of Ron Hansen. He was author of Ribbit (later called Treefrog), one of the strongest chess programs around. He generously gave me a copy of his program, which I used to learn how to write a chess program... Hansen's program was written in a computer programming language called Fortran. For my master's thesis, I translated it into the Z programming language (similar to the well known C programming language).
Everything I read about chess programs convinced me that they were ignorant; they had little in the way of chess knowledge. Of course, since I knew a lot about chess, it would be a simple matter of translating my expertise into code and voilà, success! I spent a year working on the program, adding as much knowledge as I could to it. The new program, dubbed Planner, failed to live up to my performance expectations. Gradually my enthusiasm began to wave. The chess knowledge that I had added was simple because important concepts seemed hard to program. The machine required a precise specification but my chess knowledge was imprecise. Further, for every piece of knowledge that I added, there always seemed to be an endless stream of exceptions. This was going to be harder than I thought.
I finished my master's thesis, titled ''Long Range Planning in Computer Chess'', and graduated in 1980. <ref>[[Jonathan Schaeffer]] ('''1980'''). ''Long-Range Planning in Computer Chess''. Master's thesis, Department of Computer Science, [[University of Waterloo]]</ref>
