{"content":"I'm creating an extremely difficult challenge that combines multiple complex pattern types requiring sophisticated regex techniques. This challenge includes:\n1. Mixed data formats (IPv6 addresses, credit card numbers with spaces/dashes, complex URLs)\n2. Ambiguous patterns with edge cases (almost-matching items that should be excluded)\n3. Context-sensitive matches (items that should only match in specific contexts)\n4. Variable formatting (multiple valid separators, optional components)\n5. Pattern overlaps requiring careful boundary detection and lookarounds\n6. Patterns requiring proper escaping of special regex characters\nThe target items require precise pattern matching to avoid false positives from similar-looking text.","function_call":{"name":"make_move","arguments":"{\"reasoning\": \"I'm creating an extremely difficult challenge that combines multiple complex pattern types requiring sophisticated regex techniques.
