[Date "sometimes in 1981"] [White "a much younger Aart Bik"] [Black "Chess Challenger 8 (Level 1)"] [Result "1-0"] 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. Nxe5 Qd4 6. Qh5 Qxe4+ 7. Kd1 Qxg2 8. Qxf7+ Kd8 9. Qxf8# 1-0As depicted on the corresponding photo, the Chess Challenger would admit its defeat by flashing all 64 red indicators.
The higher levels did not fall for this trick, but as Aart's chess skills improved, soon he was able to beat the highest level as well. In fact, the first time this happened, he thought he broke the computer, since the thinking indicator went off without a direct response. Only after a long delay did the computer make one of the last moves towards defeat.
Aart later also obtained the portable Mephisto Junior (shown to the left), with a manual exclusively in German (Die Bedienung des Gerätes), and the sensor-chessboard Excalibur Karpov 2294 (shown to the right).
Since those early days of playing the Chess Challenger, Aart has been fascinated by programming a computer to play chess, which eventually resulted in the development of his own UCI engine BikJump and the applications Chess for Android and Chess for Glass with full UCI and Winboard/XBoard support for third party engines.
