Build & Test (NowChessSystems) TeamCity build finished
Quiescence tactical filter only flagged capture-promotions, so a quiet queening on an empty back-rank square was treated as non-tactical and skipped at the search horizon. A bot could therefore miss a winning promotion sitting exactly at the horizon and play another move. All bots (Classical/NNUE/Hybrid) share AlphaBetaSearch and were affected. Treat every promotion as tactical so quiescence always expands it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
