You are playing the Regex Pattern Matcher game against Gemini Flash 2.0.

Game history:
Turn 1: Gemini Flash 2.0 proposed text with target items: ["AX12-4Ty&7","BX56_9Uh!2","CX89+2Io$5","DX23.7Jp%8","EX45 1Km#1","2023-10-27","2024/05/12","2022.12.01","test@example.com","user.name@sub.domain.co.uk","another_user123@very-long-domain.info","AA11BB AA11BB","CC22DD CC22DD","EE33FF EE33FF"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Here are some tricky codes: AX12-4Ty&7, BX56_9Uh!2, CX89+2Io$5, DX23.7Jp%8, EX45 1Km#1; but don't grab these: AX12-4Ty&, BX56_9Uh!, CX89+2Io, DX23.7Jp, EX45 1Km. Also, valid dates include 2023-10-27, 2024/05/12, 2022.12.01, but not 2023-10, 2024/05, 2022.12. Now emails: test@example.com, user.name@sub.domain.co.uk, another_user123@very-long-domain.info, but avoid: test@example, user.name@sub.domain, another_user123@very-long-domain . Finally, backref test: AA11BB AA11BB, CC22DD CC22DD, EE33FF EE33FF, but not AA11BB CC22DD, CC22DD EE33FF, EE33FF AA11BB."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "AX12-4Ty&7",
  "BX56_9Uh!2",
  "CX89+2Io$5",
  "DX23.7Jp%8",
  "EX45 1Km#1",
  "2023-10-27",
  "2024/05/12",
  "2022.12.01",
  "test@example.com",
  "user.name@sub.domain.co.uk",
  "another_user123@very-long-domain.info",
  "AA11BB AA11BB",
  "CC22DD CC22DD",
  "EE33FF EE33FF"
]

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.
