The artificial intelligence (AI) system named Double Agent has achieved a significant breakthrough by successfully solving a complex chess problem that had challenged experts for 58 years. Specifically, this AI discovered a unique chess position where there are 63 legal moves, and every single one of these moves results in a check. What makes this achievement even more remarkable is that Double Agent not only identified this specific position but also provided robust mathematical proof, demonstrating that it is impossible to find another chess position with a greater number of legal checking moves than 63. This groundbreaking accomplishment officially breaks the previous record, which had been established in 1968 and maintained its standing for nearly six decades. This serves as clear evidence of artificial intelligence's superior capability in analyzing and solving complex problems, opening new prospects in the field of computer chess.

Key points
* AI system Double Agent solved a 58-year-old chess problem.
* Found a chess position with 63 legal checking moves.
