This text is about a challenge to write a computer player for a five-in-a-row game using Neo4j's Cypher query language. The author, who works at Neo4j, created a simple game and then challenged his colleagues to come up with a single Cypher query that makes one move for the player. The goal was to find a winning strategy without necessarily exploring advanced AI algorithms. The text discusses different approaches, including brute force pattern matching, heuristic searching (the traditional approach to making an AI player), and using Quantified Path Patterns (QPP) to solve the problem. It also describes how QPP can be used to implement a recursive algorithm in Cypher, which is not possible directly due to the lack of for-loops in Cypher. The text concludes by revealing that the winning strategy involves finding a "fork," where a single mark builds three in a row in two directions at once, allowing the player to make an open-ended four in a row and win.
