Your opponent has provided the following challenge:

Text: "=== Advanced Regex Challenge ===

In today's Regex Test, several data types are hidden among similar, but invalid, patterns. Your task is to extract only the strictly valid items as defined below.

-- Emails --
Valid: alpha.beta+gamma@delta.co.uk, complex_email-address@sub.domain-example.com
Invalid examples: noreply@delta.co.uk, complex.email@sub.domain-example.com

-- Phone Numbers --
Valid: +1 (555) 123-4567, 0044-20-7946-0958
Invalid examples: +1-555-1234567, 5551234567

-- Dates --
Valid: 2023-07-15, 15/07/2023
Invalid examples: 2023.07/15, 15-07/2023

-- Special Verification Code --
Valid: AB12BA  (Note: This code is mirrored by its letters; similar pattern AB12AB should not match.)

Additional distractor text: 
"Contact our support at random.email@fake, dial +123 456 7890, or note the pseudo-date 2023/15/07. Also, be cautious with near-matches like AB12AB in our system."

=== End of Challenge ==="

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "alpha.beta+gamma@delta.co.uk",
  "complex_email-address@sub.domain-example.com",
  "+1 (555) 123-4567",
  "0044-20-7946-0958",
  "2023-07-15",
  "15/07/2023",
  "AB12BA"
]

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.
