In 2002 Christian Freeling put out a challenge that Havannah programs would not be able to beat him even once in a ten game match on a base-10 board, in the next ten years. Havannah is a pencil and paper game with rules that can be explained to an average 8 year old in less than a minute. The challenge remained unanswered for several years, until a new programming approach emerged, the Monte Carlo Tree Search method, that had shown some promising results in the game of Go. The programs that now won the match all use this method. They won 3 out of 10 so the winning programmers received a price of €1000 that came with the challenge.

Richard about the hardware:
"Most likely it will be a 4-core i7-2630QM CPU @ 2.00GHz, though I may get my hands on something with 2 more cores and around 2.7 GHz. But does it really matter? :)"

Timo about the hardware:
"I'm rather uncertain. Worst case it'll be an intel i2500k (4-core, 3.3ghz) box, but Marcin and I are working on some interesting ideas that may give one or both of us a nice boost."

Marcin about the hardware:
"As of today, I cannot tell you the hardware either. It may be a 6-core Intel Xeon X5650 (2.66 GHz) or something stronger (but twice more computing power definitely does not play two times better)."

Among the programs that declined the challenge in favor of stronger competitors were Ring von Fehler and Deep Fork.
