We actually did that, helping us win two consecutive world championships later,вЂќ says Bushinsky. вЂњLater on, inspired us to actually develop a new model where we better understood this phenomenon. The problem with tactics and bugs, though, is once chess programmers know about them, they can be fixed or programmed against. вЂњThere was an issue with time-keeping, so at some points it would allow itself almost no time to think even when it had time on the clock,вЂќ he writes in an email, giving one example.

Simon Waters, a British chess enthusiast, found some programming errors in the popular free program GNU Chess. One commenter writes, вЂњgreat anti-computer chess!В just watch the junior's play after move 12В вЂ“ he accomplishes nothing and just moves around his pieces while piket builds up a crushing attack!вЂќДЄnd there were people who realised that chess programs werenвЂ™t always accurately coded in the first place. Take this example, in which Junior (playing as white) is beaten by a highly defensive strategy from grandmaster Jeroen Piket (playing as black). For this, he would play defensively behind a row of pawns, knowing that with more pieces on the board, the computer found it harder to calculate an advantage because of the large number of possible moves to consider.

Boris Alterman, an Israeli grandmaster who became recognised for a series of matches against computers in the 1990s and early 2000s nicknamed his similar strategy, вЂ The Alterman WallвЂ™. вЂњThen, at some point in the game my position would be so strong that I could crash through and crush it.вЂќД«ut anti-computer tactics did not become irrelevant after 1989, or even 1997. вЂњMy long-term goal was further ahead than it could see and what would inevitably happen is that the program would tie itself up in knots,вЂќ he says. Levy would bide his time and look for opportunities that might let him take the lead. In those days, computer chess programs could plan only a restricted number of moves ahead, perhaps five or six. The computer wouldnвЂ™t be able to understand what my long-term plan was.вЂќ вЂњWhat I did was I sort of sat there making moves that improved my position in tiny ways. вЂњI called it вЂdo nothing but do it wellвЂ™,вЂќ he recalls.

They wouldnвЂ™t necessarily provide any advantage against another human but could give a player the edge over a computer opponent. He had, during all his years of practice, developed a few вЂњanti-computer tacticsвЂќ that had helped get him to that point. The achievement was reported around the world.Д«ut even by 1989, computers were succeeding against chess grandmasters and Levy knew his unbeaten streak couldnвЂ™t last forever. Less than 10 years later in 1997, IBMвЂ™s supercomputer Deep Blue would become the first to beat a reigning world champion вЂ“ Garry Kasparov вЂ“ in a tournament style game. It wasnвЂ™t until 1989, during a match hosted by the British Computer Society in London, that Levy was finally toppled by a program called Deep Thought. From the moment of agreeing the original bet with McCarthy, he remained unbeaten by computers in exhibition matches for 21 years. If the computer won the final game they would at that point be tied, but Levy persevered вЂ“ and he won.ДЄnd Levy kept winning.

The first was a draw, but he won the second and third.

In 1978, Levy found himself in Toronto, playing a computer opponent in a match which stands out as a significant milestone in the history of chess programming.
