Here is a pair of chess problems to kick off the new year. Your task is to solve both problems and work out what they have in common.
Left: Both sides cooperate to reach the position shown after White’s tenth move (starting from the usual position)
Right: Both sides cooperate to checkmate Black in two moves. Black moves first.
EDIT: This is for an on-going competition. If you have a solution, please refrain from posting until after 31st December 2020 midnight (it is probably wise to wait an extra day to account for time-zone differences since the site does not mention the time-zone)
