Researchers have developed a method to recreate historical chess playing styles using policy-only fine-tuning of neural networks. By training five distinct models on game data from different eras (1850s, 1920s, 1960s, 1990s, and 2010s), the system aims to replicate the strategic approaches of past masters rather than simply optimizing for the best move. This approach, built upon the Maia-2 model, avoids complex search algorithms, focusing instead on predicting human-like moves and blunders. The fine-tuning process is remarkably efficient, requiring only minutes per era on a laptop, and the models are designed to lose in a manner consistent with their historical period. AI
