While the Horvig bot is a powerful tool for learning and analysis, its use on competitive platforms like Chess.com or Lichess often violates if used during live games against human opponents.

Developing an engine requires a balance of speed and logic. For those interested in the architecture: High-performance C++ for the core engine. Claiming "3200" is oddly low for a cheat
