A "Chad move," as described in the hints, seems to involve
two identical (or nearly identical) flags, such as those of Chad and Romania.
These are each grouped together in sets of eight. Interpreting these as
binary gives us ASCII character codes. For example, the first group (choosing Romania as 0 and Chad as 1) gives us 01011001, which is "Y".
Continuing this pattern, we get:
01011001 01101111 01110101 00100000 01101000 01100001 01110110 01100101 00100000 01110011 01101111 01101100 01110110 01100101 01100100 00100000 01110100 01101000 01101001 01110011 00100000 01110000 01110101 01111010 01111010 01101100 01100101 00100001
or, in other words,
You have solved this puzzle!
Additionally, the title gives us
01010100 01000100, which translates as "TD", the two-letter country code for Chad. Truly a Chad move.
