2. Mate in 6 (Halumbirek)
3. Mate in 2 (?)
4. Mate Black without taking a pawn (Brown)
5. Mate in 2 (Loyd)

1. Is there a move in chess that you make in two halves?
2. Seriously, if you can't solve this one, you should give up chess!
3. Yes, Black is about to make 8 new Queens! Try moving the Knight first.
4. A puzzle inspired by the Iron Cage of Tamerlane.
5. A puzzle called 'Organ Pipes': imagine it's Black to move?
