## Executive Summary
Adding in a second neural network that guesses the identity of hidden pieces was key.

## Why It Matters (Strategic Analysis)
Overcoming Stratego's massive hidden information space and 2,000-move horizons using only 16 GPUs demonstrates that algorithmic efficiency in self-play reinforcement learning can bypass massive compute barriers, democratizing the mastery of complex imperfect-information domains.
