An AI-powered passing strategy tool built for the 2026 NMJL card. Upload the prompt or copy/paste the prompt to Claude, Chat GPT or any AI tool. Then enter your tiles, and get a coached analysis of your hand with reasoning grounded in a structured framework covering anchor identification, full card scanning, defensive filtering, and marginal tile value.
The coach works interactively: it confirms correct passes, flags incorrect ones, asks you to reconsider without giving away the answer, and can deal random hands for practice. Built and programmed by Windy City Mahjong.
This product reflects one strong, principled approach to Charleston strategy. The Charleston is inherently subjective, and there are often multiple correct answers to any passing decision — the coach is a training tool, not a rulebook. The coach can be wrong – it is not perfect.
This product is best used as a practice tool - not for live games.
