Event #92 Capture the flag

Condition: None

Whenever a piece is moved to a square on the 8th rank that piece receives a flag. If that piece manages to return to the 1st rank, then that player wins like if the opponent was checkmated. You may not leave your king in check when winning with the flag. When a piece is holding a flag, no other piece of the same color can get a flag. When a piece holding the flag gets captured, a new flag can get grabbed on the 8th rank again.

Note: For black, he needs to reach white's 1st rank to receive the flag; and white's 8th rank to win with the flag.
Note 2: You can still win by checkmating your opponent.
