The drawn game between Shredder and Jonny was the most interesting fight of the first round. After one hour of play the position was equal and so white attempted to increase the tension by sacrificing a pawn. The pressure, which resulted from the sacrifice gave white some play and hope for the future. Yet Jonny did not play materialistically but looked for dynamic opportunities. It found the best way to bring his strategic ideas into practice by returning the advantage of being a pawn up. With material at both sides equal, no side was able to take the initiative for a breakthrough or for penetrating the opponent’s position. The resultant draw was both sides acceptable.
The Junior team is well known for their creative programming skills. The current program excels in unexpected moves, marvelous variations and beautiful completions of games. In this round Junior played Hiarcs. And for the uninformed spectator it looked like a game were Hiarcs was dictating the position and possibilities. However on move 25 Junior played an unexpected sacrifice of the bishop. The compensation was a pawn and some dynamical play. For Hiarcs the situation was more difficult than expected. His position was full of weak squares that had to be protected. With a piece up it seemed not a very difficult task but Junior managed to pose time and again new problems to solve by Hiarcs. Although computers cannot be exhausted by continuous pressure Hiarcs must have been disappointed that it was unable to find a win. Still trying to find an opportunity it played 33. Qc3 whereas 33.c6 Rxc2 34. Dxc7 would have been a complex alternative. As the game went now Hiarcs could only hope for a draw but it did not realize that it should aim for a draw instead of a win. Hence it played 40.Qe4 and thereafter Junior took its chances and played well thought moves which brought Hiarcs into problems. In the end of the game we saw three black pawns moving forward, the a pawn, the f pawn and the h pawn. It forced Hiarcs to resign.
