I'm always trying to get people into unorthodox chess problems. Series problems are one of the easier types to learn, and are fun to solve. In a series problem, one side gets to make several moves in a row.
Here's a simple example that is really easy to solve:
Series mate in 25
The stipulation means that White makes 25 moves in a row. The last move should be checkmate. White may not give check until the very last move. All other chess rules remain as normal.

Black plays 7 moves in a row, aiming for a position where white has a mate-in-1. [Yes, Black plots his own demise - that's why it's called a helpmate.]
Black may not give check until his very last move.

and the second solution that i just noticed i was supposed to find. Reveal Hidden Content
promote the f pawn to a rook via taking the bishop then move it to f8. Nd6 mates.

When you see the words:

Then you can kiss goodbye to your last strands of sanity.
Look at it. Series help STALEmate in 16

Where on earth do you begin?
Fred Reinfeld never mentioned anything like this
in his 'White to Play and Win Quickly' books.
If you pay attention you'll notice that the first move can't be with the b pawn or the h pawn because that would mean there are cooks (unless they are the only chess man moved), the f pawn can't go first because it checks and the other two pawns are pinned so the first move must be a king move or one pawn moving sixteen times which is really not feasable.
