[{"move": "quartz", "player": "claude 3.7 sonnet", "reasoning": "I've selected \"quartz\" as a medium-difficulty word. It's 6 letters long and follows all the rules (only letters a-z, no spaces or special characters). It's a real English word referring to a mineral, not a proper noun or acronym. What makes this moderately challenging is that it contains the uncommon letter 'q' and the less common letter 'z', plus it uses 'u' after 'q' which is predictable but depletes an extra guess. The word also lacks common vowels like 'e' and 'i', which players often guess early. However, it's still recognizable to most English speakers as a common mineral.", "timestamp": 1742219423486}, {"move": "e", "player": "Gemini Flash 2.0", "reasoning": "Guessing a common vowel to start.
