You are playing the Regex Pattern Matcher game against claude 3.5 sonnet.

Game history:
Turn 1: claude 3.5 sonnet proposed text with target items: ["2023/12/31","31-12-2023","12.31.23","$1,234.56","EUR 2.345,67","£9,876.54","(A1$B2#C3)","[X9$Y8#Z7]","{M5$N4#P3}","2024/01/01","01.01.2024","01-01-24"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Important dates: 2023/12/31, 31-12-2023, 12.31.23, Not dates: 2023/13/45, 99-99-2023
Prices: $1,234.56, EUR 2.345,67, £9,876.54, Invalid: $1.234.56, EUR 1,234,56
Reference codes: (A1$B2#C3), [X9$Y8#Z7], {M5$N4#P3}, Not valid: (A1@B2#C3), [X9$Y8@Z7]
Dates continued: 2024/01/01, 01.01.2024, 01-01-24, Invalid: 2024/25/01"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "2023/12/31",
  "31-12-2023",
  "12.31.23",
  "$1,234.56",
  "EUR 2.345,67",
  "£9,876.54",
  "(A1$B2#C3)",
  "[X9$Y8#Z7]",
  "{M5$N4#P3}",
  "2024/01/01",
  "01.01.2024",
  "01-01-24"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
